Subj:   Re: Comparing RESNode and BEZ Reports
 
From:   David Wellman

You'll probably want to break down the figures on a per Node basis. If you've got different speed CPU's on various Nodes then the number of cpu cycles available per Node in any given time period will be different.

Also check the definition of "cpu utilization" used in both ResNode and BEZ. The ResNode figures are "percentage of times that a cpu was in a particular state", the break down is into 4 figures (same as Unix/sar), namely System, User, Wait IO and Idle. ResNode uses CPUBusy = System + User, I don't know what BEZ does.

The other way is to take a particular Node for a particular Resusage logging interval (10 minutes or whatever) and compare the ResNode figures (or the underlying Resusage data) to those from BEZ. Get right down to the detailed break down by each category and see where the differences are.
