• Monitoring over Time with Nagios: How?

  - by David

  Nagios in its standard usage monitors with point-in-time checks: either something is - or is not - true. Other tools like SGI's PCP, HP's MeasureWare, and SEC provide monitoring over time - monitoring things like average disk access time over the last five minutes, or other similar items. Is there anything like this for Nagios? I'm already running NDOUtils, which seems like a natural source for such data. I'd like to have something that would monitor and fire off alarms based on a time-based check using historical data. Is there anything like this for Nagios?

• Windows 7 trying to turn off UAC every time Windows starts

  - by Mehper C. Palavuzlar

  I have strange problem on my HP laptop. This began to happen recently. Whenever I start my machine, Windows 7 Action Center displays the following warning: You need to restart your computer for UAC to be turned off. I never disable UAC, but obviously some process or virus (I'm not sure, only guessing) causes this. As soon as I get this warning, I head for the UAC settings, and re-enable UAC to dismiss this warning. This is a bothersome situation as I really don't know what causes the problem. I have run a full scan on the computer for any probable virus activity, but TrendMicro OfficeScan said that no viruses have been found. There are no other strange incidents on the machine. Everthing works fine except this bizarre incident. How can I learn what process is trying to turn off UAC? What way should I follow to overcome this problem?

• How to verify if a clean windows 7 install was done or an upgrade over vista was what the tech did?

  - by Melody

  I'd like to know if the install was truly done as a clean Windows 7 or If the windows 7 was installed over the vista as an upgrade - 32 bit and ultimate verstion? I noticed hp game stuff (wild tanget or something ) during an virus scan and it was not suppose to be in a clean install...so now I'm wondering how to verify what kind of install Really happened/ Any help? I'd appreaciate knowing how to know the difference, if I was led to believe something that was not true...I paid for a clean install. Did I get that or not is my concern Thank you so much Melody

• My Tablet PC has a jog dial (typically used for scrolling up and down) but it does not work by defau

  - by techtechmo

  I have an HP Compaq TC4400 and I recently was able to make most of the Tablet PC functions work in Ubuntu 9.10. (The step-by-step guide can be found in my blog.) Unfortunately I have yet to make the jog dial work. This would be particularly useful for scrolling up and down websites and documents when the TC4400 is in slate mode (with no access to the keyboard). I would be much obliged if anybody could tell me: How to find out the input button/key assignment that Ubuntu 9.10 has for jog-up and jog-down; How to assign jog-up to scroll up (D-pad key UP, or PAGE UP) and jog-down to scroll down (D-Pad key DOWN, or PAGE DOWN). I am using xbindkeys to assign different shortcuts to the quick launch buttons, perhaps I could use the same program for the jog dial? I would have done that, except I do not know how to find the proper button/key assignment for xbindkeys to use. Thanks in advance!

• Increase performance of Samsung 830 256GB SSD

  - by Robert Koritnik

  I have a Samsung 830 SSD in my notebook connected to a SATA interface. This is a rather old HP notebook nc8430 which means SATA is SATA I and not II or even III that disk supports. But SATA I still supports speeds up to 150MB/s so I expected at least double values as per image below. CrystalDiskMark shows rather slow performance: I've been using this SSD for over a year now and I would like to know what to do to make it blazingly fast as other reports say it should be? Edit As suggested I'm adding AS SSD screenshot of the test. And Samsung Magician's benchmark which is likely biased...

• How to get pen input to draw?

  - by Cameron J

  I just got a crappy little Hyundai pen input module To use on a normal Windows 7 HP laptop, it works quite well with the Hyundai software, but that's in Chinese, and the input only stays on the screen for a second. When I try to use it in Paint, it just draws a dot, and switches back to an unclicked state, similarly, it's impossible to move a window. Is there ant way I can keep the click held down when the pen is touching the pad in order to draw, or is there any third party software anyone knows of that can do this?

• Seasgate GoFlex NAS + Horrible Speed = Bad Experience

  - by Jon H

  I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up? Motherboard = M3970AM-HP (Angelica) Processor = AMD FX 6100 Ram = 10GB PC3-10600 MB/sec Hard Drive (1) = 1.5TB SATA 3.0GB 5400RPM Hard Drive (2) = 120GB SATA SSD NAS = Seagate 3TB Go Flex Home Connection (1) = 1000 Base T Connection (2) = Wireless N

• About the External Graphics Card and CPU usage

  - by Balaji

  Hi, We are Rendering 16 live Streams at our client machine through one of our applications and the resolution of the video streams are as 4CIF/MPEG4/25FPS/4000Kbits. The configuration fo the client machine is below. HP Desktop Machine: Microsoft Windows XP Intel (R) Core2 Duo CPU E8400 @ 3.00 GHz 2.99 GHz, 1.94 GB of RAM Intel (R) Q45/Q43 Series Express Chipset (Inbuild) The CPU usage of the machine peaks 99% for 16 straems. After some discussion, we had decided to install external graphics card to reduce the CPU usage. So that, we have tried following graphics cards. NVIDIA Quadro NVS 440 - 128 MB Radeon HD 4350 - 512 MB GDDR2 Redeon HD 4350 - 1GB DDR2 ASUS EAH 4350 Silent 1GB DDR2 But the performance wise no difference, even worst. So, what is the pupuse of these external graphics cards? Really it will reduce the CPU usage? What parameters have to check, if we want to reduce the CPU usage? Please do the needful as soon as possible. Regards Balaji

• Is a ext3 Linux filesystem byte order independent

  - by Lothar

  I have a good old HP-C3700 Workstation with PA-RISC CPU here that I would like to use as a subversion server for a very large repository. I just worry what happens if the workstation dies (everybody who knows this computer knows that it is running like an Abrams tank and unlikely to happen in the next decade). I'm using Debian Linux on this system. If the mainboard dies can I just plug the SCSI drive into a PC and read the files from a normal Intel Linux PC? Which software RAID levels would be safe?

• Scripted printer configuration changes

  - by David Steven

  I've got about a dozen Windows XP machines that I need to make a couple specific printer configuration changes to. The printer is "virtual" printer for an electronic delivery service. I'd like to not have to visit each machine individually. I already have the means to execute commands remotely on the machines, I just can't seem to find away to adjust these settings via command line or script. Specifically I need to be able to make the following changes: 1) As an admin user: - Device Settings - Font Substitution Table/Courier New - Change to "Courier" 2) As a specific* user: - Printer Preferences - Paper/Quality - Advanced - Change Graphic/Print Quality to "600 x 600" - Change Document Options/Printer Features/Graphics Mode to "HP-GL/2" *This change is a per user configuration, unless there's some way to make it once. In this situation I only really need it for a specific (different) user on each machine.

• Help with proposed iSCSI SAN VMware implementation.

  - by obsidian

  We have four (with plans to grow to four more) Dell servers with 6 NICs. They are running VMware ESXi 4.1. We would like to connect all of them to an Openfiler iSCSI SAN via HP ProCurve 1810G switches. Based on the design below, is there anything I should be concerned about or anything unusual that I should look out for when making the iSCSI network configurations on the servers, switches and OpenFiler? Should I bond the connections on the servers or simply setup them up for failover? The primary goal is to maximize IOPS. Thanks in advance.

• Wake computer from sleep/standby without BIOS support for WOL?

  - by jjeaton

  Just bought a new home server and the nice folks at HP disabled the Wake-On-Lan feature in my motherboard. Are there any other options for waking the computer from Sleep/Standby mode? I'd like to take advantage of power savings wherever I can. I realize that I won't be able to wake it from shutdown, short of putting together some Rube Goldberg machine. EDIT: I'd like to be able to wake the machine on demand, remotely. So I can then RDP into it, or access files, etc.

• Map mouse xbuttons to keypress?

  - by Will

  Hi, the utilities that come with my HP vector mouse are fairly basic. My old logitech G9, the best mouse ever made (except when it gets senile and starts having 'gaps') had a utility to map each of the buttons to a keypress, which I use in games, such as xbutton1 and 2 for run, etc. is there a utility, or a way, that I can map the 2 xbuttons on my new mouse so that they generate/simulate a keypress? I'm wondering if there are built in mappings in Windows that do this already, and its just a case of finding out what the keypresses are? thanks, Will

• RGB to DVI adapter not working for Projector-to-PC

  - by user897052

  We have a wall-mounted projector (dell 4320) with VGA In and the other end of the cable is RGB. We have an RGB to DVI-I adapter (w/ DIP switches) inorder to plug the cable into a PC (video card has 1 VGA and 1 DVI-I port). We had no problems until recently, when the PCs hard drive crashed. After re-imaging the PC, the computer no longer "sees" the projector (the computer doesn't detect the projector as a second monitor anymore). The PC is an older Dell with an after-market video card and runs win XP. I also tried it on a new HP box (win 7), but had to add a DVI-I to DVI-D adapter. Any ideas?

• How to dispose of old rack-mount servers?

  - by Nic

  I have two old rack-mount servers lying around that I want to get rid of. One is a HP DL380 G2, the other is an IBM from the same era. Both machines boot up, but I don't have any harddrives for them, or any use for them. Worse yet, both machines appear to have been dropped at some point and the rail kits are bent out of shape and can't be removed, making them unusuable in a rack environment. I'd like to recycle them or dispose of them in some kind of safe manner, but don't really know what my options are. I'm in western Canada. Any suggestions? Update: If you found this question interesting, please consider visiting StackExchange Area 51 to support the proposal for a dedicated Recycling Q&A site.

• Optimal Configuration for five 300 GB 15K SAS Drives

  - by Bob

  I recently acquired an HP Z800 workstation that has five 300 GB 15K SAS Drives. This system will be dedicated to running multiple virtual machines under VMware Workstation (Note: I'm not using ESXi because I do plan to use the system for other purposes.). For the host OS, I plan to install RHEL 5. My number one concern is guest performance. For example, should I create a RAID 10 array for the OS and virtual machine storage with four of the drives and reserve the 5th? Or, is there a solution that will provide better performance?

• Cannot enter BIOS due to broken screen

  - by gamer

  Lately my laptop(hp g42 247sb) screen is damaged, so I hook it up with a external monitor(LG something) and it works fine now. But the only annoying thing is I cannot navigate the BIOS menu for some tweaking because the BIOS not shown on the external monitor,instead, it only shown on the broken laptop screen, and it only output to my external monitor when windwos/os is loged-on. So, is there anyway I can force output during BIOS/BOOT/POST to my external monitor? Things I have done and didn't work: (1)Set my LG monitor as primary display on both window properties and Intel Graphics panel (2)Enter the bios (F10 key) and press the fn+F4 key(change display output). (3)Disable and uninstall my internal screen(broken laptop screen) using device manager and restart, but windows(bios?) install it back on log-on. Please help me!

• perfmon reporting higher IOPs than possible?

  - by BlueToast

  We created a monitoring report for IOPs on performance counters using Disk reads/sec and Disk writes/sec on four servers (physical boxes, no virtualization) that have 4x 15k 146GB SAS drives in RAID10 per server, set to check and record data every 1 second, and logged for 24 hours before stopping reports. These are the results we got: Server1 Maximum disk reads/sec: 4249.437 Maximum disk writes/sec: 4178.946 Server2 Maximum disk reads/sec: 2550.140 Maximum disk writes/sec: 5177.821 Server3 Maximum disk reads/sec: 1903.300 Maximum disk writes/sec: 5299.036 Server4 Maximum disk reads/sec: 8453.572 Maximum disk writes/sec: 11584.653 The average disk reads and writes per second were generally low. I.e. for one particular server it was like average 33 writes/sec, but when monitoring in real-time it would often spike up to several hundreds and also sometimes into the thousands. Could someone explain to me why these numbers are significantly higher than theoretical calculations assuming each drive can do 180 IOPs? Additional details (RAID card): HP Smart Array P410i, Total cache size of 1GB, Write cache is disabled, Array accelerator cache ratio is 25% read and 75% write

• Modifying the initrd.img to run additional binaries in a PXE booted RHEL 6

  - by Charles Long

  I am trying to add additional automation to our existing RHEL 6 (or Oralce's implementation thereof) PXE install process by running a script in the %pre section of my kickstart config that call hpacucli, HP's raid device configuration binary. My approach has been to modify the PXE served initrd.img. I've unpacked the initrd.img and copied in the required libraries, binaries, and scripts but when the system boots using the modified initrd.img, the modified /lib (and /lib_64) are moved aside to /lib_old and /lib is linked to the /mnt/runtime/lib. How can I change this configuration so that the /lib is not moved (unlikely) or required libraries are available in the runtime /mnt/runtime/lib? To test and confirm this I've been able to get the install process to move to the 6th virtual console, which allows me to see errors, and then open a shell (a useful debugging mechanism). %pre exec /dev/tty6 2 /dev/tty6 chvt 6 /bin/sh

• What's required to enable communication between two IP ranges located behind one switch?

  - by Eric3

  Within our co-located networking closet, we have control over two ranges of 254 addresses, e.g. 64.123.45.0/24 and 65.234.56.0/24. The problem is, if a host has only one IP address, or a block of addresses in only one range, it can't contact any of the addresses in the other subnet. All of our hosts use our hosting provider's respective gateway, e.g. 64.123.45.1 or 65.234.56.1 A host on the 64.123.45.0/24 range can contact the 65.234.56.1 gateway and vice-versa Everything in our closet is connected to an HP ProCurve 2810 (a Layer 2-only switch), which connects through a Juniper NetScreen-25 firewall to the outside world What can I do to enable communication between the two ranges? Is there some settings I can change, or do I need better networking equipment?

• Compaq Q2009 monitor display Issues

  - by jasonco

  I have this compaq q2009 monitor 20' inches and I am having display issues. When I turn on the computer the image is displayed fine for a fraction of a second and then the display goes black. If I turn off the monitor and turn it on again the the same thing happens: the image is displayed for a fraction of a second and then goes black. This is odd. I've looked all over the web and I haven't found anything useful (not even in the HP website). So there is no "out of range" or "recommended resolution" message. It just displays and then goes black. I think the resolution is fine because it was working OK until recently and I haven't changed anything in that regard. Any help would be appreciated. Thanks.

• High fan speed after return from suspend (on Ubuntu)

  - by Bolo

  Hi, I've got a HP ProBook 5310m laptop with Ubuntu 10.04 (32 bit). When I return from suspend, the fan speed is usually very high: FDTZ sensor reports "90 °C". Yes, the units are wrong, since FDTZ does not report temperature, but fan speed – that's probably just a small bug in reporting. Interestingly, when I plug or unplug the power cable for a moment, the fan speed returns back to normal. My questions: Where can I report this problem? Is it about ACPI support in the kernel? What is the address of the relevant bug tracker? As a workaround for now, how can I programmatically trigger a behavior equivalent to (un)plugging the power cable. More generally, how can I force ACPI to recalculate fan speed? Ideally, I'm looking for something like echo foo > /proc/bar. Thanks in advance!
