find out how much a user is using resources

[IThead]

Hi,
Recently our server at some point is very low on resources, if the swap free is below 100M, system start having problem.
Is there a utility to check on how much a user is using the resources?
We are on Sun Solaris8.
Thanks

You can try the command "w" or "whodo"... Run a man page on each to see if it gives the information you are looking for.

bfitzmal,
How can I list memory/cpu useage by users?

 

[Mike042]

Not that easily, as far as I know. But a start point would be /usr/ucb/ps aux which lists the % of CPU and the % of Memory that each process is using. The command sorts the processes into order of highest CPU usage, so piping the command through a head is quite useful.

I hope that helps.

Look into prstat that is similar to the top command, it is only available on Solaris 8 and higher though.

As coffeysm says use prstat
prstat -a

gives each users resources
NPROC USERNAME SIZE RSS MEMORY TIME CPU
15 oracle 2669M 2003M 13% 1:17:11 0.9%
198 root 696M 348M 1.8% 1:54:33 0.4%
10 user2 390M 340M 2.1% 1:02:01 0.3%
2 user1 6736K 6144K 0.0% 0:00:00 0.0%
