UNIX for Dummies Questions & Answers

As a beginning UNIX administrator, I am looking for the command to display the processor usage in percentage. I am using a Sun Solaris 7.

I have tried to use the command ps -aux, but this does not give any CPU usage.

Can someone please advise me?

Thanks you.

Kind regards,

Myriam

ps -aux should be from /usr/ucb. The output should look like:

USER PID %CPU %MEM SZ RSS TT S START TIME COMMAND
root 1832 1.9 2.3 3048 2736 pts/6 O 10:48:56 0:00 /usr/ucb/ps -aux

You should be able to read the man page using
% man -s1b ps
which give you a different description of the ps command since this one is the Berkeley version of the ps command.

If you need cpu usage it gives the percentage of the cpu being used by a process and the time on the cpu (both user and system time) for the process.

You can look into the sar command if you are looking for cpu utilization (not by processes).

If you are just looking for a utility to monitor, look for top on the Internet.

You might also look into /usr/dt/bin/sdtprocess (check the man page - set /usr/dt/man in your man path)

try using vmstat...
man vmstat
