Need help on shell script to monitor each user cpu use on a cluster over time

Shell Programming and Scripting
1

Hi,

I am relatively new to the cluster administration and shell scripting. I need help on a shell script which can help me determine how many cpu's over time, any particular ( or all registered users on a cluster ) are using. To generate data say over a period of week and list of users and their cpu usage.

I will appreciate your help.

Thank you !

Hi Anuj06,

Is process accounting turned on?

Check for the file /var/log/pacct as this should have some or all the information that you need in it. It can be extracted using the "dump-acct" utility.

Or you could check and see if the sa command is available - but this can generate huge volumes of data.

It seems, I don't have permission.

couldn't open file '/var/account/pacct': Permission denied

Will this help in turning process accounting on: Process Accounting Setup on Linux

I initially thought, that may be using a script that monitor "qstat" over time,and with some command tricks I can filter required information.

Thank you ,

Anuj
