Tools or script to monitor load average on server
Hi All,
We have a server that is running RHEL4 that occasionally spikes in load average above 10 and we have no idea what is causing it. We would like to know if there are any free tools or a script that when the load average hits a certain point it will trigger the system to start logging the processes to see what is happening. Usually by the time we get logged into the system the load average is on its way down. If someone has a better idea please let me know. Thanks you, Nazs |

top vmstat iostat .... and see if you can find anything useful. Have you tried these commands btw ? |
Thanks for your response. I have tried TOP. But load average was already coming down and I did not see a process that would be causing any trouble. I will give the other command a try. Would still like to know if there was a way to log when it gets above a certain number.

Put this script in background and see if you get something useful. Code:
#!/bin/bash and run it background. Code:
bash vikas.sh & Hope this helps. |
You could try (in a script) top in batch mode, every eg 2 mins, and if it finds a high load, start other monitoring cmds.
