Let me start with the list: General: Install most current updates/service packs. Verify drivers, look for conflicts, upgrade to newer ones. Use Process Explorer to see a bit more details about what's being run Use Process Monitor(combined filemon and regmon) to see details about particular process Check the services - (services.msc from command prompt). ...

Here are a few suggestions. Is your ILO connected and configured? It will tell your exactly what's happening with the system. Please review the ILO4 log. View the system's IML log (available via ILO or vSphere "hardware" tab) Are there any indicators or error messages on the screen during crash or at POST? Are you using the HP-specific install of ESXi ...

The packet loss is not necessary an indication of a problem. Remember those are attempts to communicate with that particular network node directly. Usually those in-between router nodes are only responsible for passing traffik through to another location. They are not required to chat with you directly at all, and one that drops most of your chat should not ...

Execute sp_who2 Look at the ProgramName column and you will see something like SQL Server Profiler - 362b6154-2d69-4ce0-987b-2573bed3ce45. From that query you can define a user name and HostName...

The simplest way is at a command line do: systeminfo You will get a section that looks like: Total Physical Memory: 16,383 MB Available Physical Memory: 926 MB Page File: Max Size: 19,868 MB Page File: Available: 4,562 MB Page File: In Use: 15,306 MB That is taken directly from one of my machines. That info is near the top.

Belarc Advisor Running the advisor on a PC will generate a report to a web browser. Details cover both hardware and software of the machine with a very useful amount of detail (such as license keys for some software). From that point you could have them print the page to PDF if they have something such as Adobe Acrobat or a 3rd party pdf printer ...

You can check /var/log/messages for hints, analyze sar -A output, take a look at vmstat, iotop, dstat For really bad lockups, you also have the Magic SysRq key to squeeze some info from the system. Other places to look is the CMDB, see if there are any previous problems logged with the server and if there is an accepted workaround and or planned ...

Take a look at mtr. It's traceroute and ping consolidated into one tool and continuously monitors the path between two hosts. You get output like that below. It's available as package mtr-tiny for Ubuntu and mtr for CentOS. My traceroute [v0.75] somehost.lan (0.0.0.0) Thu Aug 18 20:52:49 2011 ...

iirc, telnet isn't installed by default on centos 6 machines anymore. if you don't have tools like telnet or nc available you can always talk to a network socket using python. (not sure if this fits your "convenient" requirement though... ) to simply test if the connection can be established: [gryphius@ut ~]$ python Python 2.6.6 (r266:84292, Feb 22 2013, ...

FYI - for any VMWare guest, if you want to get a memory dump, you can take a snapshot, then use vmss2core.exe to extract the memory to a traditional windows memory dump file that can be read using windbg, and therefore MS support or other qualified people. Converting a snapshot file to memory dump using the vmss2core tool (2003941) ...

It depends on the information you need. If you need only those policies applied to the user, run as unprivileged user, but if you also need those policies applied to the computer, you must run it with administrator privileges. You can also get applied policies to a different account using the /USER modifier running the gpresult command as administrator.

A quick google reveals inotify api in the Linux kernel. Inotify (inode notify) is a Linux kernel subsystem that acts to extend filesystems to notice changes to the filesystem, and report those changes to applications I can't find any applications that allow you to watch a file directly with inotify. However there is the inotify-tools package which ...

I think you can use audit for specific file/directory or you can write custom rule based on your requirement auditctl -w <path to the file you need to monitor> -p war -k test Where -w is for specifying file path -p is for permission access (read,write,execute and attribute change) -k key name,you can give name you can ...

If you don't want to spend any money, download a Linux livecd (my favorite http://www.sysresccd.org/), and run badblocks. Non destructive read and write test, badblocks -c 2048 -sn /dev/sdi this will re-write every block. Destructive read and write test badblocks -c 2048 -sw /dev/sde Read only test badblocks -c 2048 -s /dev/sde The -c option tells it ...

Ultimate boot cd would be the first thing I would use.

The ps command shows the running processing with their parameters. So, -k start should be the parameters passed to httpd process. You can check the listening state of apache using: $ sudo netstat -lnp | grep 80 Also, check the apache log files.

Check your memory! The most frequent cause of random segfaults like this is bad memory. Grab a memory checker (such as memtest86+) and test it.

Please try sxconsole. "sxconsole is a tool used to extract various report types and then analyze those extracted reports with plug-ins. The tool also provides an archiving structure so that all the compressed and extracted reports are saved to a directory. This tool was developed for sysreport/sosreports but has been expanded to include any report that has ...

Yes, you have some prefailure warnings, get them swapped out ASAP.

It is because you are running the program as a SERVICE. By default Cobian installs as a SERVICE. Re-install the program as a APPLICATION and the problem will go away. NOTE: If you have created a few tasks make sure you Save/export them from the file menu before you uninstall Cobian so you can re-import them after the uninstall re-install.

If memtest crashes, there is a high chance that your memory is bad. Try to replace memory from non-crashing servers and re-running memtest. Most likely the memory is the culprit. You can also reduce the memory to half (system permitting; minimum memory requirements) and try running memtest. Once passes, try replacing memory with other half and see.

Re: restart the server as a first measure...Another wonderful example of "It Depends" :-) If this is a system that is a MUST BE UP server, I don't think I'd reboot it first. I'd go through logs, maybe have a tail -f on the apache log to see what is hitting it in realtime. I'd also probably open another window and check if there's anything suspicious via ...

The Ultimate Boot CD has some Hard Drive tools on it that should detect any errors on the drive. Just make sure that you back up all your data FIRST. Doing intense testing on a bad drive may lead to worse failure and data lost.

Hmmm... hadn't heard of Smokeping. I use something pretty similar to it (almost identical), though looks like MTR has more field categories for Packet delivery and Jitter statistics.

Memtest would be the first point of call although if you can, ask the center to plug in a console next time it crashes. If the kernel is going, it should output something to screen.

I had a similar problem in the past, and it turned out to be heat related. Improving the circulation and adding a fan or two helped big-time. Also, make sure you've got SMART enabled on your disks and have a look to see if maybe one of them is on its last legs. You might want to install munin to monitor them all and see what's going on.
