  • High CPU usage in my digitalocean droplet

    - by Ibrahim Azhar Armar
    I am experiencing high CPU usage here is the stats i got from server, the consumption after every restart in 15 minutes go upto 100%, what could go wrong? I have a wordpress copy installed on the server which does not have much traffic, here is the stats that i got from using top command in server. top - 11:46:02 up 12 min, 3 users, load average: 40.89, 16.03, 6.11 Tasks: 132 total, 41 running, 91 sleeping, 0 stopped, 0 zombie Cpu(s): 24.3%us, 61.5%sy, 0.0%ni, 0.0%id, 4.0%wa, 0.0%hi, 0.0%si, 10.2%st Mem: 2050896k total, 1988656k used, 62240k free, 284k buffers Swap: 0k total, 0k used, 0k free, 4712k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 31 root 20 0 0 0 0 R 39 0.0 1:35.53 kswapd0 899 root 20 0 15988 172 0 S 14 0.0 0:05.00 irqbalance 418 syslog 20 0 243m 600 0 S 13 0.0 0:06.85 rsyslogd 944 mysql 20 0 1320m 53m 0 S 12 2.7 0:21.15 mysqld 2357 root 20 0 17344 532 164 R 11 0.0 0:14.27 top 960 root 20 0 246m 3816 0 S 3 0.2 0:08.18 php5-fpm 2431 www-data 20 0 344m 64m 908 R 2 3.2 0:04.23 apache2 2435 www-data 20 0 304m 63m 836 R 2 3.2 0:03.43 apache2 2413 www-data 20 0 349m 63m 920 R 2 3.2 0:07.51 apache2 2465 www-data 20 0 349m 64m 944 R 2 3.2 0:05.04 apache2 2518 www-data 20 0 307m 41m 1204 R 2 2.1 0:01.37 apache2 2406 www-data 20 0 346m 56m 1144 R 2 2.8 0:03.76 apache2 2456 www-data 20 0 345m 55m 1184 R 2 2.8 0:02.67 apache2 2373 www-data 20 0 351m 63m 784 R 2 3.2 0:11.09 apache2 2439 www-data 20 0 306m 35m 916 R 2 1.8 0:02.51 apache2 2450 www-data 20 0 345m 55m 1088 R 2 2.8 0:02.96 apache2 2486 www-data 20 0 299m 10m 876 R 2 0.5 0:01.19 apache2 2523 www-data 20 0 300m 27m 796 R 2 1.4 0:00.99 apache2

  • Cisco 678 Will Not Work using PPPoE - Possibly Because I Configured it Incorrectly..?

    - by Brian Stinar
    I am attempting to configure a Cisco 678 because I am totally sick on my Actiontec. However, I am running into some problems. It seems as though the Cisco is able to train the line, but I am unable to ping out. I am all right at programming, but still learning a lot when it comes to being a system administrator. I apologize in advance if I did something ridiculous, or am attempting to configure this device to do something it was not designed to do. It is almost like I am not correctly configuring the device to grab it's IP using PPPoA (like my Actiontec.) The output from "show running" (below) makes me think this too. Below are the commands I ran in order to configure this: # en # set nvram erase # write # reboot # en # set nat enable # set dhcp server enable # set PPP wan0-0 ipcp 0.0.0.0 # set ppp wan0-0 dns 0.0.0.0 # set PPP wan0-0 login xxxxx // My actual login # set PPP wan0-0 password yyyyy // My actual password # set PPP restart enabled # set int wan0-0 close # set int wan0-0 vpi 0 # set int wan0-0 vci 32 # set int wan0-0 open # write # reboot Here is the output from a few commands I thought could provide some useful information: cbos#ping 74.125.224.113 Sending 1 8 byte ping(s) to 74.125.224.113 every 2 second(s) Request timed out cbos#show version Cisco Broadband Operating System CBOS (tm) 678 Software (C678-I-M), Version v2.4.9 - Release Software Copyright (c) 1986-2001 by cisco Systems, Inc.

  • NetBackup's bplist doesn't get user/group info for Windows files

    - by Gnustavo
    I'm trying to get information about storage consumption from NetBackup's bplist output. I'm running NBU 6.0MP5 on a RHEL 3 server. The server is backing up several Solaris, Linux, and Windows machines. When I use bplist to get information about files backed up on any UNIX machine I get something like this: # bplist -C unixclient -R 99 -l -s 01/28/2006 -e 01/29/2006 / drwxr-xr-x test ccase 0 Nov 16 09:28 /l/home2/test/ -rw------- test ccase 4737 Jan 06 17:54 /l/home2/test/.bash_history -rw-rw-r-- test ccase 104 Nov 11 2004 /l/home2/test/.bashrc However, when I use it to list files backed up on any Windows client I can't get the user and group information. They both always appear as 'root'. Like this: # bplist -C winclient -t 13 -R 99 -l -s 02/20/2006 / drwx------ root root 0 Feb 20 14:26 /C/temp/ -rwx------ root root 41 Feb 20 14:26 /C/temp/asdf.txt drwx------ root root 0 May 25 2004 /C/temp/CTRMNGR/ Does anyone know why bplist doesn't show the correct user/group for Windows files? If it can't, is there a way to get that information using another command? Thanks. Gustavo.

  • Adding custom service to nagiosgraph

    - by ravloony
    I have successfully added nagiosgraph to our nagios installation. I also added a memory checker plugin, from here : http://blog.vergiss-blackjack.de/2010/04/nagios-plugin-to-check-memory-consumption/. However I can't seem to get the graph of this service to be output by nagiosgraph. The plugin returns a single line like this: 31% (3785 of 11903 MB) used so i added a rule like this to the map file: /output:(\d+)% \((\d+) of (\d+) MB\) used/ and push @s, ['Mem', ['Percentage', 'GUAGE', $1], ['Used', 'GUAGE', $2], ['Total', 'GUAGE', $3] ]; I have also read this : http://www.mail-archive.com/[email protected]/msg36835.html and made sure that process_performance_data=1 in the nagios conf file. So far I have no graph for the Mem service on any host, and no rrd file either. I am unsure how to proceed to get this working. The documentation is rather difficult to follow and I haven't managed yet to understand it enough to do this. Can anyone point me to a tutorial, or some documentation which explains the steps needed to get a service noticed and graphed by nagiosgraph?

  • ESXi 5 Guests will not boot

    - by Adrian
    I have a problem with Guests not booting under VMWare ESXi 5.0 on my IBM x3550M3 server. Note: Investigation eventually determined that problem was with the VMware client on a Lenovo Edge laptop, the only Windows box available in a Linux IT shop. vSphere Client v4 and v5 duplicated behavior on the Lenovo Edge. As indicated in the comment to the accepted answer, replacing the workstation with one using different video was the "fix" for this particular issue. The ESXi host boots just fine. The Client connects just fine. Guests can be configured but do not successfully boot. The initial guest memory consumption jumps up to 560MB and drops down to 40MB after a few seconds. Initial CPU usage is 1 full CPU (3000Ghz per the chart) and immediately drops downm to 29Mhz. Guests do not display any output in the Console tab but show a state of 'Powered On'. No errors in the Events tab. Switching Guest from BIOS to EFI makes no difference. VMs are listed as Version 7 and the behavior is duplicated across all availabled Guest OS flavors. Problem also duplicated when server is booted up in Legacy Only mode. Logs do not contain anything particularly suspicious. Edit: No firewalls, routers, or VLANs in between the client and server. Edit 2: We have tried to Boot Guest into BIOS screen at Next Boot checkbox in the Guest Setting. Was not successful. Edit 3: 500GB datastore with 1 40GB VM on it. Plenty of space. Edit 4: Guests copied from my old ESXi 4 server DO NOT boot on the ESXi 5 system. Initially it complains about too little Video RAM being configured for the default 2500x1600, but it still doesn't work properly even after I bump the Video RAM settings or switch it to Auto-Detect.

  • TCP Server Memory management: #Connections Vs. #Requests

    - by Andrew
    Given that, there is no theoretical limit to number of concurrent TCP connections a Windows 2008 server can handle. Only thing will happen is, with each connection there will be memory consumption in server. Unfortunately, memory is not unlimited (and I want to utilize only physical memory). For example, lets say we've 2GB server memory. Now there are two extreme cases: Case 1: If we've allocated 64KB buffer for each connection (only to receive incoming request), then 32768 connections can consume all the 2GB of memory. This will not leave any memory to queue/process incoming requests from those connections. Case 2: On the other hand, lets say a single (or very few) connections continuously keeps sending request buffers (for example, video streaming from one connection to other) and server cannot process them within time, those buffers will get piled up in server and eventually will occupy most of the servers memory. And it will not leave any memory for new connection thereafter. This is the real dilemma in server design bugging me badly for last many days. If I can decide on max size of request buffer per connection and max number of requests to allow in queue per connection. Then, based on available server memory, it will then automatically set limit on max number of concurrent connections. How to decide on these limits to achieve best performance and throughput? I am just looking for perfect utilization of server resources. Are there any standard guidelines or empirical data available with someone who can share with me please.

  • Why are USB 2.0 devices crashing my system?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic baby-ATX motherboard with no identifying markings. CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. There's one stamp on the motherboard that says "Rev.B". On board it has 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. It has an 80Gb Western Digital hard drive freshly formatted and built with Windows XP Professional with Service Pack 3 and all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 crashes the machine as soon as it starts up). It's got a Daytek MV150 15" touch screen running through the VGA and COM1 with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem If I hook any USB 2.0 devices to this machine, it hangs the whole machine and I have to hard boot it to get it back up. Workarounds found I can plug the same devices into the on board USB 1.0 connectors and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions I've tried disabling all the on board devices that I'm not using - such as the on board LAN, the second COM port, the AGP connector etc. through the BIOS in an (perhaps misguided or futile) attempt to reduce the power consumption... I don't think it had any effect but it didn't do any harm. I was wondering if the PSU wattage just isn't enough to drive the USB 2.0 devices; I've seen this suggested but haven't found any confirmation that this could really be an issue - nor have I found a way to work around this issue - if indeed it is one. Any ideas? The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference. I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself. Other thoughts Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

  • What is the difference between these Pentium Extreme Edition CPUs?

    - by Giffyguy
    The CPU in question is the Pentium Extreme Edition 955. Intel's website shows four "versions", but for the most part they all look identical. They even share the same set of ordering codes. But one of them has a substantially lower TDP, which is seemingly unexplainable - since everything else is the same. Two of them say "LGA775, Tray" and I have no idea what "Tray" means either. Also, two of them have a different SPEC code. What I need to know is: What does "LGA775, Tray" mean? Why does the one CPU have a lower TDP? And what does that mean for me? Does that mean lower maximum power consumption? Does it mean the CPU may be more stable/endurant, because of a lower heat output? Why do two of them have a different SPEC code, and what does this mean? Finally, what does PLGA775 (as opposed to LGA775) mean, and do I need to be worried about that? Information from Intel's wbsite: Intel® Pentium® Processor Extreme Edition 955 (4M Cache, 3.46 GHz, 1066 MHz FSB) with SPEC Code 1 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 95 Watts BX80553955 SL94N 2 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL94N 3 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 130 Watts BX80553955 SL8WM 4 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL8WM

  • College network - can I point non-domain student computers to our SUS server?

    - by Joel Coel
    Since I started here 3 months ago, one of the things that's really bothered me about the way this network is setup is something that shows up on the daily bandwidth consumption report. I get a list of top-visited sites by hits and by size, and invariably the top site (to the point that it's bigger than all the other top sites combined) is au.download.windowsupdate.com. We're pulling in ~30GB/day in windows updates. This is every day, not just after a patch Tuesday. After a patch day, it jumps closer to 40GB for a couple days. The key here is that almost none if it is by machines that I'm responsible for. My machines are for the most part fully patched, and when they're not they'll pull from a SUS server, so new updates are downloaded only once. It used to be closer to 50GB/day because most of the machines in our computer labs use DeepFreeze and weren't applying updates correctly, but that's fixed now. So the problem is definitely student-owned machines in the dorms, some of which are re-downloading the same updates in background each day, over and over. I'd love to have these machines start pulling from our SUS server. Then, if they don't ever actually install them at least they're not leeching bandwidth from our public internet connection. Any ideas on how to resolve the situation?

  • 100% CPU load on Ubuntu 10.04.3 LTS 64bit

    - by deadtired
    I have 2 days since I am trying to fix this issue, with no success. The server is a mysql database server. Hardware: DELL Poweredge 1950, 2x Intel Xeon Quad Core E5345 @ 2.33GHz, 16 Gb mem, 2x 146Gb SAS (software RAID1) Software: Ubuntu 10.04.3 LTS, MySQL 5.1.41 Issue: while mysql is not used and runs with no database, everything seems alright. As soon as I install a database, it has the reason to bring all 8 cores in 100% with low memory consumption. So, you can imagine the load average goes high (I saw 212 load average for the first time). The server doesn't become unresponsive, but you can see it's slow while browsing the project installed. Additional info: the database used is not more than 24MB and it was moved from a server with less resources and a lot more larger databases. So it's not the database/project. my.cnf is not a reason also, as I used both default one and the one I use on the same distribution on another server.What is interesting is that mysql doesn't close any process and runs to the limit of the max_connections. Logs are quiet. Nothing there. I switched to this Ubuntu version after I suspected some problems in the newly Ubuntu 11.10 server. This one worked alright for an hour after I made a kernel upgrade to 3.0.1 (it was using the memory also) I tested disk speed and seems alright. Some more output on the running server: dstat -cndymlp -N total -D total 3: htop command: Idea? Did anyone meet the same problem? Any fix you can think of?

  • What seems to be plaguing my hard drives?

    - by Craig
    In a little bit of a tech nightmare here. I know oodles about software, not so much more than the above average user about hardware. I recently had to toss an old desktop of mine. It was gradually getting slower and slower, and after shutting the desktop down for long periods of time, it would choke up upon startup. Sometimes it'd give a disk read error, sometimes say no OS was found, etc. Restarting it about 5-15 times would eventually boot properly. Weird. I also noticed that startup programs were going missing, Dropbox was reindexing my entire folder, and Backblaze was backing up less than the number of files that it should. This lead me to believe it was probably a hard drive issue. I began to wonder why I'd have hard drive issues, and came to closure when I assumed it was because of recent power surges and outages. I'm sure that does a number on the drive. I bought a new desktop recently. It's not a beast or anything, but it's enough for what I do. It's an eMachines (I know, I know) Ultra-Slim (http://www.amazon.com/eMachines-Ultra-Slim-ER1401-57-Desktop-PC/dp/B00475OG9U). This is ideal for me because it's small and portable. It comes with an AC adapter and battery, like a laptop. Just to be safe, I bought an uninterruptable power supply on top of that. It's basically protected completely from any outages that might scramble the drive. I set this up a few days ago and for the past few days I've been perfecting settings, downloading the usual applications, etc. Two days ago, I noticed Dropbox was reindexing my entire Dropbox folder. I installed both Dropbox and Backblaze on this system, but it is very much more lightweight than the other. Only about 15 third-party applications installed. I thought that maybe Dropbox and Backblaze were stressing my system, so I turned off Backblaze. Still, Dropbox runs and comes across this infinite reindex issue. I noticed that upon a reboot recently, two applications did not start on startup either. Also, much like my old desktop, every 3rd or 4th reboot, I'll be forced into a chkdsk. This makes me incredibly nervous. What could possibly be going wrong with my old, years-old desktop that is immediately causing the same issues to my new one? I've considered all of the basics. I'm in a very air conditioned room. I take run routine virus scans. I'd like to think I take care of my systems very well. What is this issue that is haunting me? There's always the possibility that this new desktop has a junk hard drive, but it just seems way too coincidental.

  • Do hard drive enclosures fail/is it the HDD or enclosure?

    - by x0a
    I'm having a whole host of problems with an external hard drive that was working just fine a couple of hours ago. I've had this problem before once, and that was about 3 months ago, here's what I documented: So a couple of hours ago I turned off all my computers and shut off the power to all my devices in my room, then went and turned the power off at the main switch so I could change an outlet. A couple hours later, after I've already slowly turned everything back on, I go to my xbox to try and watch a movie and it can't seem to list any of the movies I've got. So I go to my desktop to find that my external hard drive isn't there.. even though it's on and connected. It's also stationary and hidden behind something so there's not a whole lot of tampering/physical wear to that external. I plug it into my laptop to try and see what's going on. It starts making this endless loud screeching noise. None of that clicking that's usually associated with hd damage. It's not listed in my computers, and it shows up in Disk Management as "uninitialized" asking me to choose between two different partition types. After carefully disconnecting it and connecting it back, it asks me to format it, which I cancel. I start googling about my issue, starting to accept the situation, torn as hell and helpless and just about ready to toss the thing. Suddenly the screeching stops, after almost 45 minutes of it going, and Disk Management lists the drive as "Online" and "Healthy". Explorer pops up with all my files! I'm still being really careful with it and weary and treating it as though it's in fragile shape. I've downloaded some S.M.A.R.T. software to read the values and everything is listed as "OK" . No reallocated sectors, no read errors, no seek errors. I also ran a quick self-test, which completed without error. Everything seems fine. It looks to be a perfectly healthy external hard drive. So what the hell was that about? Was it doing some sort of maintenance or self-test? How am I supposed to tell the difference? I would've undoubtedly killed the drive for sure if had it gone on a bit longer. I've got the same problem now, with one exception: it doesn't magically reappear after the screeching stops. Occasionally I manage to get some S.M.A.R.T. diagnostics information, which basically reads everything as fine. The only problem is that my HD isn't initializing (so I can't access anything in it). I'm able to successfully run a quick smart test but not an extended one (I've only tried it once but got conflicting indications as to whether it was actually making any progress or not (was stuck on Random read test). So, final question (if all else fails): Could the hard drive enclosure be failing rather than the HDD? Is this a likely possibility at all? How would I know?

  • Looking to get a small server – need web, PHP, PostgreSQL.

    - by Javawag
    Hi all! I'm looking to get a cheap (low end) server to serve web pages (xHTML/PHP), but I also need to be able to set up PostGreSQL on the system too. Ideally the server would have low power consumption, run Linux (I prefer Mac OS X but a Mac Mini, although the size I'm looking for, is too much money!) and be around £100 (~$160US). EDIT: Just to make it clearer, I'm looking to purchase the server hardware myself – but I want something about Mac Mini sized. I don't want to pay for hosting! Also, quick question – if it's to serve web pages from my home (standard ISP connection, no static IP!), what do I need in place to get this working. I'm guessing I would sign up with some service like no-ip, and register a domain to point to my no-ip address (then install the no-ip software on the server to update that with the current IP). I know the idea of running a server behind a normal ISP connection isn't very elegant, but I'd prefer to have the server where I can see it then pay over the odds for a hosting service where I have little to no control over what happens. Also, I could write my own server software for apps/etc to connect to as well. Anyways I'm rambling! What do you guys think?! Javawag

  • Vista 64-bit, DISK BOOT FAILURE

    - by weka
    So I have this Acer Aspire AX3200-U3600A with Windows Vista (64-bit). Every night I turn it off and turn it back on in the morning. Around three weeks ago, I did a fresh factory reimage. Good as new. Then around two days ago, when I turned it on, I noticed it was running extremly slow. As in, it would often freeze up while I had multiple applications open when it usually never froze up. So I decided to restart my computer. Big mistake. My computer froze right after I clicked shut-down. I waited a while. Nothing. Waited some minutes. Nope. I decided to shut it down by pressing the power button. Here is where the problems begin. When I turned it back on, I saw the Windows logo and loading bar and then it loaded to black. I turned it off again forcefully by power button and then once more... then I got: AMD Data Change... Update New Data to DMI! then later the screen clears and I get: AHCI Option ROM BIOS Revision: 01.05.92 Date: 02-19-2008 Copyright (c) 2006-2008 Phoenix Technologies, LTD Port 01: Reset Port Error!! Port 02: then the screen clears again but this time, this loads from the bottom: Nvidia Boot Agent 249.0542 (copyright stuff... blah blah) PXE-E61: Media test failure, check cable. PXE-M0F: Exiting Nvidia Boot Agent DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. So I try to go into Safe Mode. Well, first of all it doesn't load as fast. After it loads disk.sys from windows/drivers, it will wait a while (2-3 mins) THEN load. However it loads the Acer eRecovery Management Tool. I have three options: Reset computer to factory default, Restore computer from user's backup, or Exit. However, the top two options are gray and disabled where as the Exit is in blue and definitely clickable. So obviously safe mode is not there... A strong thing to note: In the beginning when all of this started, I did a Boot Windows Normal from pressing f8 and I got to my desktop! It logged me in. I could see the icons on my files. However my desktop was extremely slow as in when I clicked on the Start menu, it would wait a while, then load up the menu with JUST the gradient, no text or icons... so as you can see... it saw my HDD? Also, before anyone says, I have NO USB plugged in. My mouse and keyboard are not USB inputs, I assure you. And this came without a recovery CD AND when I went in BIOS, to change the BOOT ORDER, I did NOT see a CD-ROM option. And when I tried pressing ALT+F10 to get into Acer eRecovery Management, the top two options were disabled as well. But sometimes on start-up, I get: Windows has encountered a problem communicating with a device connected to your computer. This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removeable storage is properly connected and then restart your computer. If you continue to receive this error message, contact the hardware manufacturer. Status: 0xc00000e9 Info: An unexpected I/O error has occured. Then I tried Last Known Good Configuration Settings, that gives me a BSOD. What should I do/

  • Pushing Windows Store apps silently

    - by seagull
    As part of a requirement I have been issued, I seek the ability to push apps from the Windows Store (.appx) to remote users. The framework surrounding the data transmission is sorted; What I need to know is if there is a script that can be sent out along with a URI or the package proper to facilitate installation on the user-side of the Windows Store app. I am well aware that numerous guides exist from Microsoft on pushing out Line-of-Business (LOB) (AKA Enterprise) applications -- that is, apps that have been developed in-house and are not for the consumption of the Windows store. This is inappropriate for my requirement, however; the customer wants their clients to receive apps that appear currently on the Windows Store, and for them to be installed in a silent manner. I've seen this guide; http://blogs.technet.com/b/keithmayer/archive/2013/02/25/step-by-step-deploying-windows-8-apps-with-system-center-2012-service-pack-1.aspx, which details doing exactly this, but it is only applicable to machines that are administered by a system running Windows Server 2012 R2 with the 'System Center 2012' bundle installed. The systems I target are considerably more decentralised than this, making this guide inappropriate. I have a hunch that Microsoft have deliberately designed the Windows Store to be this way, but I figured I ought to ask around before I resign myself to the requirement. Much obliged

  • windows 2008 r2 iis worker proccess memory usage increase

    - by nLL
    I have this web site written in c#. around 400-500 users online at any time. it was on windows 2008 32 bit machine before and never ever locked/slowed down due to increased memory consumption up until i upgraded it's server to win 2008 r2 64 bit. Old server had only 4 gig ram and quad core cpu at 2ghz. site was working just fine. since i've upgraded the server i noticed (2 times with in 10 days) it started to eat ram. last night it went up to 4 gb ram. with ram increase response slows down quite a lot. recycling app pool doesn't help. I have to restart it's worker process to recover. i've noticed this usually happens if there are continuous errors. as i didn't change anything in the code am i safe to assume it is not related to memory leak in the code? did anyone came across something like that? same thing happens if i create continuous errors with classic asp. thanks

  • How can I read PDFs with e-reader on a Lenovo tablet?

    - by Jack M
    This is my first time using a tablet and I'm totally lost - this must be what computers look like to old people. This is a Lenovo Thinkpad tablet. I don't see a specific model number on it (it was passed down to me second hand). What I'd like to do is read a PDF. I'm fairly certain I successfully transferred the PDF onto the tablet via an SD card, and I noticed this thing has an app called "eReader" on it, so I started that up. All I see are empty bookshelves, and no obvious buttons or settings anywhere. I saw in multiple places that you have to, as one site puts it: ...copy and paste the relevant files into the eBooks folder and they will appear on the eReader shelf for your consumption... But I have no idea how to: Access the file system. Locate the eBooks folder. Copy and paste files. Will I need a file explorer app? If so, how can I install that given that my only method of getting data onto this tablet is an SD card (no wireless internet).

  • What I should know about memory management?

  • Why is piping dd through gzip so much faster than a direct copy?

    - by Foo Bar
    I wanted to backup a path from a computer in my network to another computer in the same network over a 100MBit/s line. For this I did dd if=/local/path of=/remote/path/in/local/network/backup.img which gave me a very low network transfer speed of something about 50 to 100 kB/s, which would have taken forever. So I stopped it and decided to try gzipping it on the fly to make it much smaller so that the amount to transfer is less. So I did dd if=/local/folder | gzip > /remote/path/in/local/network/backup.img.gz But now I get something like 1 MB/s network transfer speed, so a factor of 10 to 20 faster. After noticing this, I tested this on several paths and files and it was always the same. Why does piping dd through gzip also increase the transfer rates by a large factor instead of only reducing the bytelength of the stream by a large factor? I'd expected even a small decrease in transfer rates instead, due to the higher CPU consumption while compressing, but now I get a double plus. Not that I'm not happy, but just wondering. ;)

  • How does the Cloud compare to Colocation? And development too

    - by David
    Currently I/we run a SaaS web application where each subscriber has their own physical instance of the application in addition to their own database. The setup has each web application instance deployed on two different IIS boxes both for load-balancing and redundancy (the machines have their Windows Update install times 12 hours apart, for example). Databases are mirrored on two different SQL Server 2012 machines with AlwaysOn for uptime. I don't make use of SQL Server clustering (as it doesn't provide storage-level failover: we don't have a shared storage box). Because it's a Windows setup it means there are two Domain Controllers (we cheat: they're both Mac Minis, 17W each, which keeps our colo power costs low). Finally there's also an Exchange server (Mailbox, Hub Transport and Client Access). One of the SQL Servers also doubles-up as an Exchange Hub Transport. Running costs are about $700 a month for our quarter-rack colocation (which includes power and peering/transfer), then there's about $150 a month for SPLA licensing, so $850 a month in total. Then there's the hard-to-quantify cost of administration, but I reckon I spend a couple of hours a week checking-in on the servers: reviewing event logs, etc. I keep getting bombarded by ads and manufactured news stories about how great "the cloud" is. Back in 2008 when the cloud was taking off I was reading up about the proper "cloud" services like Google AppEngine, where you write in Python against Google's API and that's how they scale your application across servers and also use their database provider for scaling storage. Simple enough to understand. Then came along Amazon, and I understand how Amazon Storage works, but I'm not sure how Amazon Compute works: web application pages don't take much CPU time to compute, how do you even quantify usage anyway? Finally, RackSpace gets in the act and now I'm really confused. RackSpace advertise "Cloud" SQL Server 2012 available for about "$0.70 per hour", going by how they advertise it I thought the "hour" meant the sum of CPU time, IO blocking time, maybe time spent transferring data, so for a low-intensity application that works out pretty cheap then? Nope. I went on to a Sales Chat window and spoke to one of their advisors. They told me the $0.70/hour was actually for every hour the SQL Server is running... but who wants a SQL Server for only a few hours? You're going to need it available 24 hours a day for months on end. $0.70 * 24 * 31 works out at $520 a month, which is rediculously expensive for SQL Server. An SPLA license for SQL Server is only $50 a month or so. That $520 a month does not include "fanatical support", and you also need to stack on top the costs of the host Windows server instance too. From what I can tell, Rackspace's "Cloud" products seem like like an cynical rebranding of an overpriced VPS service, but priced by the hour. I have the same confusion about Windows Azure which uses similar terms to describe the products available, but I think that's because Azure offers both traditional shared webhosting in addition to their own APIs you can target for scalable applications.

  • Can a VM perform better when only two cores instead of four cores are presented to it?

    - by arcain
    We had a VMWare VM at work with two cores allocated to it that ran a pretty heinous process in IIS. Under load the process was maxing out the CPU usage on both cores, so we asked our system engineers to present the other two cores of the physical processor to the VM. The engineer immediately said that this would not improve performance at all, but would make the VM perform worse. That statement didn't make much sense to me, and I'm wondering how what the engineer said could be true. Are there actually cases where four cores presented to a VM would cause worse performance than two cores on the same physical hardware? Let's assume an ideal situation where there's only one VM on the host server, so nothing is being shared with other OS instances. I believe the physical server had a single quad core processor, and was most likely hosting multiple VMs. I don't really know what version of ESX was running on the host, nor do I know with certainty what the physical processor config was, but from within the VM I had access to, I saw two 3.33 GHz AMD processors. In the end, I never got to test the engineer's assertion out because (while we were trying to get the VM upgraded) we were able to optimize the process and reduce it's CPU consumption, and 2) we ended up migrating to a different VM on another ESX server which had four cores presented to it.

  • Monitor randomly shutting down, computer accepting no input, need to restart to get working

    - by Sebastian Lamerichs
    First off, spec list: OS: Windows 7 Ultimate 64-bit SP1 CPU: i7-4820k @ 3.7GHz (stock) GPU: Two 3GB Radeon HD 7970s @ 1.05GHz Mobo: AsRock X79 Extreme6 HDD: 2TB Seagate Barracuda 7200rpm RAM: 16GB quad-channel Kingston 1600MHz PSU: Antec HCG 900W Monitors: Acer S220HQL 1920x1080 + ViewSonic VA2251 1920x1080. Plugged into different GPUs. My problem is that, on a daily-ish basis, my monitors will turn off and not turn back on. My computer will still be running, GPU/CPU/case fans all still going, but the monitors will not turn back on. Additionally, it seems to cease all network activity. It doesn't seem to log any errors at all. I've verified that this is not a monitor issue, as when I press the num/caps/scroll lock buttons on my keyboard, the lights don't change, so the computer is clearly not accepting input. I have noticed a few other people on the internet with this problem, and some have claimed that it was solved by disabling PCI-Express Link State Power Management, but the issue still occurs for me after this. Whilst my CPU and GPUs both run at 100% 24/7, the temperatures are certainly not at dangerous levels, with the CPU averaging 65°C and the GPUs at 70°C and 78°C average. All components are brand new. I have tried forcing MSI Afterburner to start when Windows starts and to force a constant voltage, as this fixed the issue for a few days for another user, but he reported back saying that it had stopped working properly again, so I'm not putting too much faith in this working. Many people have said to adjust display sleep mode settings, but this will clearly not work, as the keyboard lights would still work if the monitors were the issue. The closest I can get to a log file for this issue is the following Folding@Home logs: 14:45:21:WU01:FS00:0x17:Completed 1120000 out of 2000000 steps (56%) 14:46:43:WU00:FS01:0x17:Completed 480000 out of 2000000 steps (24%) 14:46:49:WU01:FS00:0x17:Completed 1140000 out of 2000000 steps (57%) 14:48:30:WU01:FS00:0x17:Completed 1160000 out of 2000000 steps (58%) 14:49:55:WU01:FS00:0x17:Completed 1180000 out of 2000000 steps (59%) As you can see, the second GPU (FS01) stops computation approximately three and a half minutes before the issue occurs (it should be completing 1% every 80-120 seconds), and the first GPU (FS00) continues for a few minutes more before the logs just end. As far as I can tell, the computer has a network failure at the time the first GPU stops working, the latest IRC message I received from this time was at 14:47:58. That being said, there could have just not been any messages between then and 14:50:00, so I'm going to be connecting a laptop to the same bouncer to double-check if it happens again. The GPUs functioned perfectly well in another computer for a significant period of time, so I'm fairly confident that they aren't the issue, which means that this is being caused by either software or the motherboard, or possibly RAM. I really hope it's software. I heard from a forum board that there was a patch from Microsoft that fixed this problem, but "I've forgot which KB it was or the google search terms I used to find the patch, LOL.", so that's not much help. Haven't seen it mentioned by anyone else on about a dozen threads about this issue either. The computer is plugged in via a surge-protected power board, and I've run several other computers and pieces of hardware through it with no issues, so that is not the cause. I have just set the hard disk to never turn off, although I don't believe that that will solve the issue. Strangely, this has only happened when I'm not at the computer (which is actually a minority of the time). Until today it had only happened when I had not been actively using the computer for 6 hours, but today it happened within 10-30 minutes of me last using the computer actively. I have enabled file logging from MSI Afterburner, so hopefully this will shed some light on the issue, but I'm not too optimistic. I've heard that it could be a motherboard problem, but I figured I should ask around before RMAing it. Any help?

  • 1 PC, 2 consoles (as in 2 monitors, keyboards and mice)

    - by ciuly
    I have this desire to "kill 2 birds with one shot". Currently, I have 1 server running round the clock, 1 laptop that runs about 8 hours a day, 7 days a week, and a desktop that runs about the same length of time. All 3 are ... old, to say the least. So there is a great need to upgrade (well, the server might handle its job for another year or so, but that only depends on how much time I have to put it to "work"). Now, I'm "dreaming" of only one PC. I'm thinking vmware's ESX. So there will be a VM for the server, a VM for the "laptop" and one for the "desktop". And obviously I'll have to somehow "link" a set of monitor/keyboard/mouse with one of the laptop/desktop VMs. The server doesn't need such things, obviously (it doesn't have them at this moment either). Is something like this possible? ESX is not a requirement, it's just something I found that answers part of my problems, but there still remains the 2 KVM set that needs connecting and "linking" to appropriate VM. Why I would want to do this? well, first of all, it's much cheaper to upgrade one PC than 3. Then, the power consumption is obviously lower. Plus the extra space.Plus it allows me to better separate networks and services. Thanks.

  • Part 2&ndash;Load Testing In The Cloud

    - by Tarun Arora
    Welcome to Part 2, In Part 1 we discussed the advantages of creating a Test Rig in the cloud, the Azure edge and the Test Rig Topology we want to get to. In Part 2, Let’s start by understanding the components of Azure we’ll be making use of followed by manually putting them together to create the test rig, so… let’s get down dirty start setting up the Test Rig.  What Components of Azure will I be using for building the Test Rig in the Cloud? To run the Test Agents we’ll make use of Windows Azure Compute and to enable communication between Test Controller and Test Agents we’ll make use of Windows Azure Connect.  Azure Connect The Test Controller is on premise and the Test Agents are in the cloud (How will they talk?). To enable communication between the two, we’ll make use of Windows Azure Connect. With Windows Azure Connect, you can use a simple user interface to configure IPsec protected connections between computers or virtual machines (VMs) in your organization’s network, and roles running in Windows Azure. With this you can now join Windows Azure role instances to your domain, so that you can use your existing methods for domain authentication, name resolution, or other domain-wide maintenance actions. For more details refer to an overview of Windows Azure connect. A very useful video explaining everything you wanted to know about Windows Azure connect.  Azure Compute Windows Azure compute provides developers a platform to host and manage applications in Microsoft’s data centres across the globe. A Windows Azure application is built from one or more components called ‘roles.’ Roles come in three different types: Web role, Worker role, and Virtual Machine (VM) role, we’ll be using the Worker role to set up the Test Agents. A very nice blog post discussing the difference between the 3 role types. Developers are free to use the .NET framework or other software that runs on Windows with the Worker role or Web role. Developers can also create applications using languages such as PHP and Java. More on Windows Azure Compute. Each Windows Azure compute instance represents a virtual server... Virtual Machine Size CPU Cores Memory Cost Per Hour Extra Small Shared 768 MB $0.04 Small 1 1.75 GB $0.12 Medium 2 3.50 GB $0.24 Large 4 7.00 GB $0.48 Extra Large 8 14.00 GB $0.96   You might want to review the Windows Azure Pricing FAQ. Let’s Get Started building the Test Rig… Configuration Machine Role Comments VM – 1 Domain Controller for Playpit.com On Premise VM – 2 TFS, Test Controller On Premise VM – 3 Test Agent Cloud   In this blog post I would assume that you have the domain, Team Foundation Server and Test Controller Installed and set up already. If not, please refer to the TFS 2010 Installation Guide and this walkthrough on MSDN to set up your Test Controller. You can also download a preconfigured TFS 2010 VM from Brian Keller's blog, Brian also has some great hands on Labs on TFS 2010 that you may want to explore. I. Lets start building VM – 3: The Test Agent Download the Windows Azure SDK and Tools Open Visual Studio and create a new Windows Azure Project using the Cloud Template                   Choose the Worker Role for reasons explained in the earlier post         The WorkerRole.cs implements the Run() and OnStart() methods, no code changes required. You should be able to compile the project and run it in the compute emulator (The compute emulator should have been installed as part of the Windows Azure Toolkit) on your local machine.                   We will only be making changes to WindowsAzureProject, open ServiceDefinition.csdef. Ensure that the vmsize is small (remember the cost chart above). Import the “Connect” module. I am importing the Connect module because I need to join the Worker role VM to the Playpit domain. <?xml version="1.0" encoding="utf-8"?> <ServiceDefinition name="WindowsAzureProject2" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> <WorkerRole name="WorkerRole1" vmsize="Small"> <Imports> <Import moduleName="Diagnostics" /> <Import moduleName="Connect"/> </Imports> </WorkerRole> </ServiceDefinition> Go to the ServiceConfiguration.Cloud.cscfg and note that settings with key ‘Microsoft.WindowsAzure.Plugins.Connect.%%%%’ have been added to the configuration file. This is because you decided to import the connect module. See the config below. <?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="WindowsAzureProject2" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="1" osVersion="*"> <Role name="WorkerRole1"> <Instances count="1" /> <ConfigurationSettings> <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.ActivationToken" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Refresh" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.WaitForConnectivity" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Upgrade" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.EnableDomainJoin" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainFQDN" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainControllerFQDN" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainAccountName" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainPassword" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainOU" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Administrators" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainSiteName" value="" /> </ConfigurationSettings> </Role> </ServiceConfiguration>             Let’s go step by step and understand all the highlighted parameters and where you can find the values for them.       osFamily – By default this is set to 1 (Windows Server 2008 SP2). Change this to 2 if you want the Windows Server 2008 R2 operating system. The Advantage of using osFamily = “2” is that you get Powershell 2.0 rather than Powershell 1.0. In Powershell 2.0 you could simply use “powershell -ExecutionPolicy Unrestricted ./myscript.ps1” and it will work while in Powershell 1.0 you will have to change the registry key by including the following in your command file “reg add HKLM\Software\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell /v ExecutionPolicy /d Unrestricted /f” before you can execute any power shell. The other reason you might want to move to os2 is if you wanted IIS 7.5.       Activation Token – To enable communication between the on premise machine and the Windows Azure Worker role VM both need to have the same token. Log on to Windows Azure Management Portal, click on Connect, click on Get Activation Token, this should give you the activation token, copy the activation token to the clipboard and paste it in the configuration file. Note – Later in the blog I’ll be showing you how to install connect on the on premise machine.                       EnableDomainJoin – Set the value to true, ofcourse we want to join the on windows azure worker role VM to the domain.       DomainFQDN, DomainControllerFQDN, DomainAccountName, DomainPassword, DomainOU, Administrators – This information is specific to your domain. I have extracted this information from the ‘service manager’ and ‘Active Directory Users and Computers’. Also, i created a new Domain-OU namely ‘CloudInstances’ so all my cloud instances joined to my domain show up here, this is optional. You can encrypt the DomainPassword – refer to the instructions here. Or hold fire, I’ll be covering that when i come to certificates and encryption in the coming section.       Now once you have filled all this information up, the configuration file should look something like below, <?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="WindowsAzureProject2" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="2" osVersion="*"> <Role name="WorkerRole1"> <Instances count="1" /> <ConfigurationSettings> <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.ActivationToken" value="45f55fea-f194-4fbc-b36e-25604faac784" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Refresh" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.WaitForConnectivity" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Upgrade" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.EnableDomainJoin" value="true" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainFQDN" value="play.pit.com" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainControllerFQDN" value="WIN-KUDQMQFGQOL.play.pit.com" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainAccountName" value="playpit\Administrator" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainPassword" value="************************" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainOU" value="OU=CloudInstances, DC=Play, DC=Pit, DC=com" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Administrators" value="Playpit\Administrator" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainSiteName" value="" /> </ConfigurationSettings> </Role> </ServiceConfiguration> Next we will be enabling the Remote Desktop module in to the ServiceDefinition.csdef, we could make changes manually or allow a beautiful wizard to help us make changes. I prefer the second option. So right click on the Windows Azure project and choose Publish       Now once you get the publish wizard, if you haven’t already you would be asked to import your Windows Azure subscription, this is simply the Msdn subscription activation key xml. Once you have done click Next to go to the Settings page and check ‘Enable Remote Desktop for all roles’.       As soon as you do that you get another pop up asking you the details for the user that you would be logging in with (make sure you enter a reasonable expiry date, you do not want the user account to expire today). Notice the more information tag at the bottom, click that to get access to the certificate section. See screen shot below.       From the drop down select the option to create a new certificate        In the pop up window enter the friendly name for your certificate. In my case I entered ‘WAC – Test Rig’ and click ok. This will create a new certificate for you. Click on the view button to see the certificate details. Do you see the Thumbprint, this is the value that will go in the config file (very important). Now click on the Copy to File button to copy the certificate, we will need to import the certificate to the windows Azure Management portal later. So, make sure you save it a safe location.                                Click Finish and enter details of the user you would like to create with permissions for remote desktop access, once you have entered the details on the ‘Remote desktop configuration’ screen click on Ok. From the Publish Windows Azure Wizard screen press Cancel. Cancel because we don’t want to publish the role just yet and Yes because we want to save all the changes in the config file.       Now if you go to the ServiceDefinition.csdef file you will see that the RemoteAccess and RemoteForwarder roles have been imported for you. <?xml version="1.0" encoding="utf-8"?> <ServiceDefinition name="WindowsAzureProject2" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> <WorkerRole name="WorkerRole1" vmsize="Small"> <Imports> <Import moduleName="Diagnostics" /> <Import moduleName="Connect" /> <Import moduleName="RemoteAccess" /> <Import moduleName="RemoteForwarder" /> </Imports> </WorkerRole> </ServiceDefinition> Now go to the ServiceConfiguration.Cloud.cscfg file and you see a whole bunch for setting “Microsoft.WindowsAzure.Plugins.RemoteAccess.%%%” values added for you. <?xml version="1.0" encoding="utf-8"?> <ServiceConfiguration serviceName="WindowsAzureProject2" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="2" osVersion="*"> <Role name="WorkerRole1"> <Instances count="1" /> <ConfigurationSettings> <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.ActivationToken" value="45f55fea-f194-4fbc-b36e-25604faac784" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Refresh" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.WaitForConnectivity" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Upgrade" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.EnableDomainJoin" value="true" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainFQDN" value="play.pit.com" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainControllerFQDN" value="WIN-KUDQMQFGQOL.play.pit.com" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainAccountName" value="playpit\Administrator" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainPassword" value="************************" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainOU" value="OU=CloudInstances, DC=Play, DC=Pit, DC=com" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.Administrators" value="Playpit\Administrator" /> <Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainSiteName" value="" /> <Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.Enabled" value="true" /> <Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountUsername" value="Administrator" /> <Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountEncryptedPassword" value="MIIBnQYJKoZIhvcNAQcDoIIBjjCCAYoCAQAxggFOMIIBSgIBADAyMB4xHDAaBgNVBAMME1dpbmRvd 3MgQXp1cmUgVG9vbHMCEGa+B46voeO5T305N7TSG9QwDQYJKoZIhvcNAQEBBQAEggEABg4ol5Xol66Ip6QKLbAPWdmD4ae ADZ7aKj6fg4D+ATr0DXBllZHG5Umwf+84Sj2nsPeCyrg3ZDQuxrfhSbdnJwuChKV6ukXdGjX0hlowJu/4dfH4jTJC7sBWS AKaEFU7CxvqYEAL1Hf9VPL5fW6HZVmq1z+qmm4ecGKSTOJ20Fptb463wcXgR8CWGa+1w9xqJ7UmmfGeGeCHQ4QGW0IDSBU6ccg vzF2ug8/FY60K1vrWaCYOhKkxD3YBs8U9X/kOB0yQm2Git0d5tFlIPCBT2AC57bgsAYncXfHvPesI0qs7VZyghk8LVa9g5IqaM Cp6cQ7rmY/dLsKBMkDcdBHuCTAzBgkqhkiG9w0BBwEwFAYIKoZIhvcNAwcECDRVifSXbA43gBApNrp40L1VTVZ1iGag+3O1" /> <Setting name="Microsoft.WindowsAzure.Plugins.RemoteAccess.AccountExpiration" value="2012-11-27T23:59:59.0000000+00:00" /> <Setting name="Microsoft.WindowsAzure.Plugins.RemoteForwarder.Enabled" value="true" /> </ConfigurationSettings> <Certificates> <Certificate name="Microsoft.WindowsAzure.Plugins.RemoteAccess.PasswordEncryption" thumbprint="AA23016CF0BDFC344400B5B82706B608B92E4217" thumbprintAlgorithm="sha1" /> </Certificates> </Role> </ServiceConfiguration>          Okay let’s look at them one at a time,       Enabled - Yes, we would like to enable Remote Access.       AccountUserName – This is the user name you entered while you were on the publish windows azure role screen, as detailed above.       AccountEncrytedPassword – Try and decode that, the certificate is used to encrypt the password you specified for the user account. Remember earlier i said, either use the instructions or wait and i’ll be showing you encryption, now the user account i am using for rdp has the same password as my domain password, so i can simply copy the value of the AccountEncryptedPassword to the DomainPassword as well.       AccountExpiration – This is the expiration as you specified in the wizard earlier, make sure your account does not expire today.       Remote Forwarder – Check out the documentation, below is how I understand it, -- One role in an application that implements a remote desktop connection must import the RemoteForwarder module. The two modules work together to enable the remote desktop connections to role instances. -- If you have multiple roles defined in the service model, it does not matter which role you add the RemoteForwarder module to, but you must add it to only one of the role definitions.       Certificate – Remember the certificate thumbprint from the wizard, the on premise machine and windows azure role machine that need to speak to each other must have the same thumbprint. More on that when we install Windows Azure connect Endpoints on the on premise machine. As i said earlier, in this blog post, I’ll be showing you the manual process so i won’t be scripting any star up tasks to install the test agent or register the test agent with the TFS Server. I’ll be showing you all this cool stuff in the next blog post, that’s because it’s important to understand the manual side of it, it becomes easier for you to troubleshoot in case something fails. Having said that, the changes we have made are sufficient to spin up the Windows Azure Worker Role aka Test Agent VM, have it connected with the play.pit.com domain and have remote access enabled on it. Before we deploy the Test Agent VM we need to set up Windows Azure Connect on the TFS Server. II. Windows Azure Connect: Setting up Connect on VM – 2 i.e. TFS & Test Controller Glad you made it so far, now to enable communication between the on premise TFS/Test Controller and Azure-ed Test Agent we need to enable communication. We have set up the Azure connect module in the Test Agent configuration, now the connect end points need to be enabled on the on premise machines, let’s have a look at how we can do this. Log on to VM – 2 running the TFS Server and Test Controller Log on to the Windows Azure Management Portal and click on Virtual Network Click on Virtual Network, if you already have a subscription you should see the below screen shot, if not, you would be asked to complete the subscription first        Click on Install Local Endpoints from the top left on the panel and you get a url appended with a token id in it, remember the token i showed you earlier, in theory the token you get here should match the token you added to the Test Agent config file.        Copy the url to the clip board and paste it in IE explorer (important, the installation at present only works out of IE and you need to have cookies enabled in order to complete the installation). As stated in the pop up, you can NOT download and run the software later, you need to run it as is, since it contains a token. Once the installation completes you should see the Windows Azure connect icon in the system tray.                         Right click the Azure Connect icon, choose Diagnostics and refer to this link for diagnostic detail terminology. NOTE – Unfortunately I could not see the Windows Azure connect icon in the system tray, a bit of binging with Google revealed that the azure connect icon is only shown when the ‘Windows Azure Connect Endpoint’ Service is started. So go to services.msc and make sure that the service is started, if not start it, unfortunately again, the service did not start for me on a manual start and i realised that one of the dependant services was disabled, you can look at the service dependencies and start them and then start windows azure connect. Bottom line, you need to start Windows Azure connect service before you can proceed. Please refer here on MSDN for more on Troubleshooting Windows Azure connect. (Follow the next step as well)   Now go back to the Windows Azure Management Portal and from Groups and Roles create a new group, lets call it ‘Test Rig’. Make sure you add the VM – 2 (the TFS Server VM where you just installed the endpoint).       Now if you go back to the Azure Connect icon in the system tray and click ‘Refresh Policy’ you will notice that the disconnected status of the icon should change to ready for connection. III. Importing Certificate in to Windows Azure Management Portal But before that you need to import the certificate you created in Step I in to the Windows Azure Management Portal. Log on to the Windows Azure Management Portal and click on ‘Hosted Services, Storage Accounts & CDN’ and then ‘Management Certificates’ followed by Add Certificates as shown in the screen shot below        Browse to the location where you saved the certificate earlier, remember… Refer to Step I in case you forgot.        Now you should be able to see the imported certificate here, make sure the thumbprint of the certificate matches the one you inserted in the config files        IV. Publish Windows Azure Worker Role aka Test Agent Having completed I, II and III, you are ready to publish the Test Agent VM – 3 to the cloud. Go to Visual Studio and right click the Windows Azure project and select Publish. Verify the infomration in the wizard, from the advanced settings tab, you can also enabled capture of intellitrace or profiling information.         Click Next and Click Publish! From the view menu bar select the Windows Azure Activity Log window.       Now you should be able to see the deployment progress in real time.             In the Windows Azure Management Portal, you should also be able to see the progress of creation of a new Worker Role.       Once the deployment is complete you should be able to RDP (go to run prompt type mstsc and in the pop up the machine name) in to the Test Agent Worker Role VM from the Playpit network using the domain admin user account. In case you are unable to log in to the Test Agent using the domain admin user account it means the process of joining the Test Agent to the domain has failed! But the good news is, because you imported the connect module, you can connect to the Test Agent machine using Windows Azure Management Portal and troubleshoot the reason for failure, you will be able to log in with the user name and password you specified in the config file for the keys ‘RemoteAccess.AccountUsername, RemoteAccess.EncryptedPassword (just that enter the password unencrypted)’, fix it or manually join the machine to the domain. Once you have managed to Join the Test Agent VM to the Domain move to the next step.      So, log in to the Test Agent Worker Role VM with the Playpit Domain Administrator and verify that you can log in, the machine is connected to the domain and the connect service is successfully running. If yes, give your self a pat on the back, you are 80% mission accomplished!         Go to the Windows Azure Management Portal and click on Virtual Network, click on Groups and Roles and click on Test Rig, click Edit Group, the edit the Test Rig group you created earlier. In the Connect to section, click on Add to select the worker role you have just deployed. Also, check the ‘Allow connections between endpoints in the group’ with this you will enable to communication between test controller and test agents and test agents/test agents. Click Save.      Now, you are ready to deploy the Test Agent software on the Worker Role Test Agent VM and configure it to work with the Test Controller. V. Configuring VM – 3: Installing Test Agent and Associating Test Agent to Controller Log in to the Worker Role Test Agent VM that you have just successfully deployed, make sure you log in with the domain administrator account. Download the All Agents software from MSDN, ‘en_visual_studio_agents_2010_x86_x64_dvd_509679.iso’, extract the iso and navigate to where you have extracted the iso. In my case, i have extracted the iso to “C:\Resources\Temp\VsAgentSetup”. Open the Test Agent folder and double click on setup.exe. Once you have installed the Test Agent you should reach the configuration window. If you face any issues installing TFS Test Agent on the VM, refer to the walkthrough on MSDN.       Once you have successfully installed the Test Agent software you will need to configure the test agent. Right click the test agent configuration tool and run as a different user. i.e. an Administrator. This is really to run the configuration wizard with elevated privileges (you might have UAC block something's otherwise).        In the run options, you can select ‘service’ you do not need to run the agent as interactive un less you are running coded UI tests. I have specified the domain administrator to connect to the TFS Test Controller. In real life, i would never do that, i would create a separate test user service account for this purpose. But for the blog post, we are using the most powerful user so that any policies or restrictions don’t block you.        Click the Apply Settings button and you should be all green! If not, the summary usually gives helpful error messages that you can resolve and proceed. As per my experience, you may run in to either a permission or a firewall blocking communication issue.        And now the moment of truth! Go to VM –2 open up Visual Studio and from the Test Menu select Manage Test Controller       Mission Accomplished! You should be able to see the Test Agent that you have just configured here,         VI. Creating and Running Load Tests on your brand new Azure-ed Test Rig I have various blog posts on Performance Testing with Visual Studio Ultimate, you can follow the links and videos below, Blog Posts: - Part 1 – Performance Testing using Visual Studio 2010 Ultimate - Part 2 – Performance Testing using Visual Studio 2010 Ultimate - Part 3 – Performance Testing using Visual Studio 2010 Ultimate Videos: - Test Tools Configuration & Settings in Visual Studio - Why & How to Record Web Performance Tests in Visual Studio Ultimate - Goal Driven Load Testing using Visual Studio Ultimate Now that you have created your load tests, there is one last change you need to make before you can run the tests on your Azure Test Rig, create a new Test settings file, and change the Test Execution method to ‘Remote Execution’ and select the test controller you have configured the Worker Role Test Agent against in our case VM – 2 So, go on, fire off a test run and see the results of the test being executed on the Azur-ed Test Rig. Review and What’s next? A quick recap of the benefits of running the Test Rig in the cloud and what i will be covering in the next blog post AND I would love to hear your feedback! Advantages Utilizing the power of Azure compute to run a heavy virtual user load. Benefiting from the Azure flexibility, destroy Test Agents when not in use, takes < 25 minutes to spin up a new Test Agent. Most important test Network Latency, (network latency and speed of connection are two different things – usually network latency is very hard to test), by placing the Test Agents in Microsoft Data centres around the globe, one can actually test the lag in transferring the bytes not because of a slow connection but because the page has been requested from the other side of the globe. Next Steps The process of spinning up the Test Agents in windows Azure is not 100% automated. I am working on the Worker process and power shell scripts to make the role deployment, unattended install of test agent software and registration of the test agent to the test controller automated. In the next blog post I will show you how to make the complete process unattended and automated. Remember to subscribe to http://feeds.feedburner.com/TarunArora. Hope you enjoyed this post, I would love to hear your feedback! If you have any recommendations on things that I should consider or any questions or feedback, feel free to leave a comment.
