System event on AIX

Hi,
on AIX 6,
are the system events historicized ? I want to know how was the performance on 18th of march. Is there any way ?

thanks and regards.

Check the man page for the command errpt . You can specify time ranges etc.

you can use the sar command to view some basic system performance stats from recent dates.

Being able to review this information in any real meaningful way requires planning. Set up a cacti server or set up nmon statistic gathering or use some other tool.
