• XXClone as a tool for migrating Windows XP Home from PATA to SATA HD

  - by raw_noob

  Has anybody had any experience using XXClone as a tool for cloning an existing installation of Windows in order to move it from an old PATA drive to a new, larger SATA without having to reinstall everything? Did you have any problems? Or can you recommend an alternative (free) software tool that you know - preferably from repeated experience - is reliable? I'm looking to move Windows XP Home SP3 to a new disk: same file system, same partition size. Thanks for looking.

• Using Java to retrieve the CPU Usage for Window's Processes

  - by stjowa

  Hello all, I am looking for a Java solution to finding the CPU usage for a running process in Windows. After looking around the web, there seems to be little information on a solution in Java. Keep in mind, I am not looking to find the CPU usage for the JVM, but any process running in Windows at the time. I am able to retrieve the memory usage in Java by using the exec("tasklist.exe ... ") to retrieve and parse process information. Although there is an aggregate CPU cycle timer for each process, I do not see a CPU usage column. Any help would be greatly appreciated. Also, if possible, I would like to stay away from C libraries; however, if there is no other alternative, a solution by that means would be appropriate. Thanks a lot, Steve

• ASP.NET retrieve Average CPU Usage

  - by Sam

  Last night I did a load test on a site. I found that one of my shared caches is a bottleneck. I'm using a ReaderWriterLockSlim to control the updates of the data. Unfortunately at one point there are ~200 requests trying to update the data at approximately the same time. This also coincided with CPU usage spikes. The data being updated is in the ASP.NET Cache. What I'd like to do is if the CPU usage is around 75%, I'd like to just skip the cache and hit the database on another machine. My problem is that I don't know how expensive it is to create a new performance counter to check the cpu usage. Also, if I would probably like the average cpu usage over the last 2 or 3 seconds. However, I can't sit there and calculate the cpu time as that would take longer than it's taking to update the cache currently. Is there an easy way to get the average CPU usage? Are there any drawbacks to this? I'm also considering totaling the wait count for the lock and then at a certain threshold switch over to the database. The concern I had with this approach would be that changing hardware might allow more locks with less of a strain on the system. And also finding the right balance for the threshold would be cumbersome and it doesn't take into account any other load on the machine. But it's a simple approach, and simple is 99% of the time better.

• Cannot get Windows snipping tool to auto run with AutoHotKey

  - by jasondavis

  I am trying to get Windows 7 sniping tool to run when I hit my PRINTSCREEN keyboard button with AUTOHOTKEY. I have been unsuccessful so far though. Here is what I have for the AutoHotKey script. I have tried this PRINTSCREEN::Run, c:\windows\system32\SnippingTool.exe and this PRINTSCREEN::Run, SnippingTool.exe and this PRINTSCREEN::Run, SnippingTool And all those give me this error when I hit the PRINTSCREEN button... It basicly says it cannot find the file, however the file path seems to be correct, I can copy paste it into a window and it opens the snipping tool, any ideas why it will not work? Here is the full code to my AHK file... ; ; AutoHotkey Version: 1.x ; Language: English ; Platform: Win7 ; Author: Jason Davis <friendproject@> ; ; Script Function: ; Template script (you can customize this template by editing "ShellNew\Template.ahk" in your Windows folder) ; #NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases. SendMode Input ; Recommended for new scripts due to its superior speed and reliability. SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory. /* PRINTSCREEN = Will run Windows 7 snipping tool */ PRINTSCREEN::Run, c:\windows\system32\SnippingTool.exe return

• Best grep-like tool

  - by e-satis

  I do in file search a lot, and used to love grep. Then I learn the existence of egrep, so I switched to benefit from the advanced regexp. Then I discovered the Eclipse search tool. Much easier to use that grep. Then I found ack : fast, easy, powerful. And now I use grin, which is smooth for pythonistas. I know there is also a couple of this kind of tools with a GUI. So what tool do you use, and why do you think it's the best. Practical features generally are : fast to fire and use; speedy processing; automatically ignore useless files; colored output; output lines, filename, context; allow complex regexp; allow a custom filtering and ouput; GUI + command line intergation; let you open an editor from the result set. There are some related posts on SO : http://stackoverflow.com/questions/87350/what-are-good-grep-tool-for-windows http://stackoverflow.com/questions/981601/colorized-grep-viewing-the-entire-file-with-highlighting http://stackoverflow.com/questions/1028107/is-there-some-unix-util-that-will-allow-me-to-grep-multiple-files-with-little-type http://stackoverflow.com/questions/1027906/unix-find-grep-syntax-vs-awk

• Application usage report on XenApp 6

  - by Garrett

  We just deployed the latest Citrix XenApp 6 onto Server 2008 R2, and we'd like to run an application usage report. I've googled around, but all the how-to's seem to be aimed at XenApp 5 and lower, when apparently it was much easier. I came across this Citrix expert thread: http://forums.citrix.com/thread.jspa?threadID=265554 Which gives a powershell command, Get-XAApplicationReport, but when I run that on our Citrix Server in PS2 it says it's not recognized. Do I need to register the Citrix commands in PS some how? Is there a better way to generate the application usage report?

• Load balanced asp.net websites and required memory usage

  - by Matt

  Each of my servers has 8Gb RAM and the memory usage hovers around 7Gb. I have a load balancer available to me but at the moment I'm worried that putting my sites through it will cause the platform to fall over. The load balancer would be configured with a sticky round-robin where a new connection is round robin but subsequent connections for the same source ip will remain on the same server (until a limit is reached). Thats all standard stuff. How do I know what memory usage my sites will need across the platform when I put them through the load balancer? Rather than knowing that a site is using 150mb on a particular server I could face a situation where the 150mb is taken up on each of the servers. I know that with only 1 gb free I could have a serious problem on my hands. If I free up some memory then how can I work out what I need to have free to prevent this from happening? Thanks Matt

• display internet usage agreement before users can use internet

  - by Force Flow

  I was looking for a way to display a usage agreement page in browsers that users must agree to before they are allowed to access the internet. This would be for users on public computers and public/open wifi. I'm using a sonicwall firewall which does support this feature, however, there is a rediculously low character limit which makes it impractical to use. I thought about setting the browser's homepage to a usage agreement page, but that can easily be bypassed by navigating to somewhere else. Are there any other approaches that may be worth considering? There is currently no server in place on the public network, though I can set one up if need be.

• Correlating %RDY in esxtop to CPU Usage in Guest

  - by Joe

  We recently upgrade a number of our VmWare hosts from 4.1 to 5.5 and noticed many of the VMs saw a step-wise jump in CPU usage as shown by the guest VM. We have not yet upgraded vmwaretools on any of the guests, but after investigating a bit more we saw many of these guests with a high %RDY value (50%) when viewed under esxtop. Unfortunately Linux (the guest) just shows "high CPU usage" without any insight into what portion of that is coming from %RDY (VmWare saying, "your guest is waiting on CPU from the host"). Are there any tools, /proc entries, etc. that can shed light on that information?

• CentOS 7: PHP high CPU usage

  - by HTF

  I've migrated Observium monitoring platform from CentOS 6.5 to CentOS 7 and I've noticed high CPU usage mostly caused by PHP, the CPU load increase when pooling script is running (poller-wrapper.py). Both VMs are running on the same physical host (KVM hypervisor) with exactly the same spec. I also tested this with a simple PHP benchmark script and CentOS 7 is slower - is it strictly related to PHP version (5.4.30 vs 5.4.16)? CentOS 6.5 [root@centos6:~]# php -f bench.php -------------------------------------- | PHP BENCHMARK SCRIPT | -------------------------------------- Start : 2014-08-19 22:26:34 PHP version : 5.4.30 Platform : Linux -------------------------------------- test_math : 1.610 sec. test_stringmanipulation : 1.416 sec. test_loops : 0.822 sec. test_ifelse : 0.729 sec. -------------------------------------- Total time: : 4.577 sec.

• Best suited multi-function printer for Linux usage from a few choices

  - by Nakedible

  I want a cheap multi-function printer for Linux usage. I'm looking for rock solid scanning and printing that works with big images. I'd prefer drivers that are available in Debian, or other drivers that are open source, but will settle for proprietary drivers if they are well contained and clean. Some choices I have are: Samsung SCX-4300 HP LaserJet M1120 MFP Samsung SCX-4500 Canon i-SENSYS MF4010 Brother DCP-7040 I am also interested in opinions what printer communication language is best for Linux usage for cheap printers. PostScript is nice, of course, but low-end PostScript printers often have problems when printing complex (large) PostScript files. It seems Samsung printers use SPL for communication, HP uses XQX and ZJS, then there's ofcourse PCL.

• Plesk on Windows Server 2008 memory usage

  - by Thomas

  I have a server running IIS and Plesk. There is a problem every day now in which the memory usage of PleskControlPanel.exe and w3wp.exe slowly increases. And at some point all of the sites hosted on the server go down. Restarting Plesk through its panel will reset its memory usage for a while, and restarting IIS will make it last even longer, but there is still the constant memory climbing problem. I cannot see anything by looking through the event viewer. Has anyone ever seen anything like this with Plesk on Windows? Thanks for any help.

• SharePoint Web Analytics not tracking usage for main application

  - by Chris W

  My SP 2010 setup is two separate applications - one for the main portal and one for MySite. Whilst WebAnalytics is tracking usage of MySite it's not showing any stats for the main Portal. The only thing it lists is the number of site collections but no page views etc. The WA service is clearly running to pick up data for MySite. In Configure web analytics and health data collection everything is ticked. I can't find any obvious settings that are different between the two applications. Where should I look to get usage tracking correctly?

• Why does my iTunes use so much CPU time?

  - by bikesandcode

  I have a roughly 2 year old Macbook (10.5). I have iTunes 10. When iTunes is playing MP3s, I see CPU usage of the iTunes process in the system monitor ranging from 65%-75%. When I pause the music, I see CPU usage of about 65%-75%. I do not have any visualisations going, to my knowledge I have not turned on any CPU destroying features, my music library isn't tiny, but it's hardly huge (3GB). This is mildly annoying when I'm plugged into the wall as I only have slightly longer compile times, but if I am out and about, this is a major drain on the battery. Using VLC I see CPU loads of ~= 10% at the most when listening to music and generally lower. What the heck is iTunes doing?

• Am I using too much memory? (Rails on EC2 with Resque)

  - by Stpn

  I am looking at the memory usage of the Rails application (it uses background processes via Resque) and since the common answer to the question, "how many workers is too many" was "test and see", I ran some memory commands and wonder if someone can help figuring if the memory usage is high enough already, or I can still add some extra workers.. so (this is all under the maximum load): $ free -t -m total used free shared buffers cached Mem: 1756 1532 223 0 12 229 -/+ buffers/cache: 1291 464 Swap: 895 10 885 Total: 2652 1543 1108 $ vmstat procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 10588 156172 13400 326476 1 6 4 0 5 4 1 0 99 0 If there is any extra info I can provide to help answer this, I would be happy to do so. If the question is strange in some way, please let me know I'd be glad to fix etc..

• Free / Cached / Available memory on Linux

  - by pkoraca

  I have read that linux uses free memory for caching, to make system faster. However, both Nagios and Paessler PRTG monitoring system show me that my memory usage is critical. I could change Nagios mem_usage script to sum free and cached memory, but would that be correct information? I doubt that they misunderstood Linux memory usage. Lets say I have 8 GB RAM. 5 GB are used, 2 GB is cached, and I have 1 GB of free memory. Real available memory should be free+cached (3 GB)? If some new application would need additional 3 GB RAM, could it take everything from cache and free without using swap, or is there a minimum that should be in cache? Real example: $ cat /proc/meminfo MemTotal: 5984256 kB MemFree: 137052 kB Buffers: 140484 kB Cached: 3439616 kB SwapCached: 244 kB Active: 3148824 kB Inactive: 2341768 kB ... My monitoring tools show that I have 137 MB free RAM, however I have ~3,5 GB in Cache. Thanks!

• SQL Server suddenly using only a small portion of CPU.

  - by hermiod

  We've got a Windows 2008 R2 server running SQL Server 2008. All of a sudden, the SQLServer process is refusing to go above 20% CPU usage. As of last week, when running a heavy query against the db it would rise to 100% usage as I would expect. We've had this server for a while and it seems strange that it would just suddenly have this limit. This limit is causing our queries to take a lot longer than they normally would. No one has (knowingly at least) made any changes to the server configuration. After a bit of investigation, I discovered the sys.dm_os_sys_memory view. This shows 'available physical memory is high' bu at the same time the available physical memory is 339552kb where as the total is 4193848kb. It is worth noting that this is a virtual server running on vmware. Is there a setting somewhere with in SQL Server that sets the maximum CPU usage? I've found the settings in resource governor, although this is currently off as it always has been. We have recently started using Spotlight for SQL Server by Quest Software. It's playback database was located on this server for a short time this morning, I first noticed the problem shortly afterwards, although I hadn't been doing any queries prior to this so I don't know if this is the point at which the problem began, however the database was working as expected on Friday afternoon. The Windows log shows that the following settings were applied to the SpotlightPlaybackDatabase when it was created. 02/21/2011 08:45:02,spid60,Unknown,Setting database option TORN_PAGE_DETECTION to ON for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option MULTI_USER to ON for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option READ_WRITE to ON for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option AUTO_UPDATE_STATISTICS to ON for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option AUTO_CREATE_STATISTICS to ON for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option ANSI_WARNINGS to OFF for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option CONCAT_NULL_YIELDS_NULL to ON for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option RECOVERY to SIMPLE for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option QUOTED_IDENTIFIER to OFF for database SpotlightPlaybackDatabase. 02/21/2011 08:45:02,spid60,Unknown,Setting database option AUTO_CLOSE to OFF for database SpotlightPlaybackDatabase. Could any of these settings changes modified the settings applied to the whole server?

• Cherokee high virtual memory usage even after disabling I/O Cache

  - by nidheeshdas

  I've Ubuntu 10.04LTS 64-bit running on a openvz container and Cherokee 1.0.8 compiled from source. The virtual memory usage of cherokee-worker is around 430 MB even after disabling I/O cache from Advanced - I/O Cache - NOT enabled. Is this issue particular to openvz? Because many people reported to have successfully reduced virt memory usage by disabling io cache. htop output: http://imgur.com/z5JEL.jpg (newbies not allowed to post image.) thanks in advance. nidheeshdas

• innodb memory usage mysql

  - by Tiddo

  I have a small vps, with only 256mb of ram, with maximum burst up to 512mb. When I configure my vps without innodb, it only uses 130 mb of ram, so that is no problem for me. But when I turn on innodb, The memory usage grows to about 300-400 mb. Is it possible to run innodb such that I won't exceed the 256mb? preferably I don't want to use more than 100mb for innodb. I already came across some sites which said I could limit the memory usage, but if I limit it to only 100mb will the db run well enough? (compared to for example the MyISAM storage engine) If 100mb is to little memory for innodb, can you recommend me any other storage engine which supports transactions?

• Tool to track bandwidth by domain name?

  - by Grant Limberg

  I'm running an Ubuntu 10.04 server that hosts several domain names. All domains point to the same IP address and use the same network interface. I'm really only concerned with the main domain name such as my-domain1.com and my-domain2.com. It should include subdomains such as www.my-domain1.com with the totals for my-domain1.com. Is there a tool out there that is configurable to track bandwidth usage on a per-domain name basis? Edit: I'm not looking for only web usage. I'm looking for all traffic.

• Tools for tracking disk usage

  - by Carey

  I manage a number of linux fileservers. These all run applications written from 0-10 years ago. As sometimes happens, a machine will come close to, or run out of disk space. Reasons include applications not rotating log files, a machine with 500GB of disk producing 150GB of new files every month that were not written to tape, databases gradually increasing in size, people doing silly things...generally a bit of chaos. Anyway, when a machine unexpectedly goes from 50% to 100% full in a couple of hours, I figure out what broke (lots of "du") and delete files or contact someone. I also can look at cacti graphs to figure out what the machine's normal disk usage is (e.g. for /home). Does anyone know of any tools that will give finer grained information on historial usage than a cacti/RRD graph? Like "/home/abc/xyz increased 50GB in the last day".

• Windows 7 unreasonable ram usage

  - by Deus Deceit

  I have a fresh install of windows 7, and my ram in normal startup goes up to 2.5 GB. I looked at task manager, and there's at least 1.5 GB missing from there and in resource monitor as well. No indication of what's using that ram. Can someone tell me how I can find out what's consuming my memory? I believe it's a virus but none of the free antivirus programs tracked it down. EDIT I added the pictures bellow. If this is normal usage of windows 7 as some answers imply... then I don't get this at all. P.S My windows 8 Installation was running bellow 2.5 gb actually it was 1. something, until recently that I transferred some files from another computer which had the same problem that mine has now. I deleted windows 8 and installed 7, since i would do that anyway. And now I'm getting high memory usage in windows 7 as well.
