I'm trying to write some scripts that'll monitor parts of Nmon output on a daily/weekly basis. For reasons I'm not at liberty to go into, I can't use the nmon analyzer tool for these -- only for the monthly reports. So I'm trying to duplicate the nmon analyzer logic in my scripts.
What formulas does nmon_analyzer use to calculate CPU_SUMM?
(I tried looking at the source code, but what I know about VisualBasic I could write on my thumbnail and have space left over. I quickly got confused.)

Re: Formula for CPU_SUMM in nmon analyzer2012-10-16T20:39:05ZThis is the accepted answer. This is the accepted answer.It is simply the average of the numbers on the related CPU TABs that get moved to the far right. CPU01 is um CPU number 1!!
Also the Weighted Averages - see the analyser documentation for how that is calculated.
I think you should consider Ganglia and lpar2rrd to do all the stats collecting and maths for you. and present the data online so you don't have to write reports.

In re your Ganglia suggestion: it's an excellent one. I'll have to look into it.
