AIX 5.2 - nmon CPU% lies

[MoshiachNow]

Hi,

Looks like the numbers nmon displays are unrealistic - the total is often more then 100%.
Anything that can be done about it ?

perhaps it depends on number of proc you have ?

Thanks,possibly.
But what I'd expect is to get the global CPU consumption by a certain process.
A certain CPU consumption display does not really reflect on this program total load.

How much over 100% are we talking? I know sar often displays totals which taken together add to more than 100%, probably because of rounding.

What I mean that If sum up the CPU percentage - I'll be way over 100%.ex:

Top Processes Procs=135 mode=3 (1=Basic, 2=CPU 3=Perf 4=Size 5=I/O w=wait-procs)
PID %CPU Size Res Res Res Char RAM Paging Command
