SAR to the rescue

You can get activity reports with this linux command. I especially like this article showing different usages:

Or, per user, you can use sa:

http://www.gnu.org/software/acct/manual/html_chapter/accounting_6.html#SEC20

$ sa --user-summary
                                       23       0.13re       0.01cp         0avio      3163k
root                                    9       0.13re       0.01cp         0avio      3588k
ssperandeo                              3       0.00re       0.00cp         0avio      1467k

All time. It saves it to a file. – Homer6 Nov 20 '12 at 18:02
A lot of thanx! – Nov 20 '12 at 18:18
Have a problem.From man: sa summarizes information about previously executed commands as recorded in the acct file. But what about execute now program? For example, nodes? How can I view information about not complete process? – Devoll Nov 22 '12 at 14:51
