Subj:   Re: Monitoring System CPU

  Can anyone advise on the best way to monitor CPU usage throughout the day? (E.g. one thing >we would like to do is identify 'Highs and Lows' during the day - so that we can move some of our scheduled jobs which require more resources to run at quieter times on the box).  


You can run the macro dbc.resCPUbyNode, which will report CPU utilization at whatever interval you have resUsage logging set to. Exec dbc.resCPUbyNode('FromDate', 'ToDate', 'FromTime', 'ToTime', 'FromNode', 'ToN ode') -> exec dbc.resCPUByNode('2004-08-04','2004-08- 04','00:00:00','23:59:59','000-00','999-99') for example. There are also other resCPU macros.byAMP, byGROUP etc.

NCR also probably has sar set up writing to a file every 20 minutes during the day / 1 hr at night as well. Look in /var/adm/sa. Sar -f sa<date> to view.
