The #CPUs (y-axis) show the values twice on the System Summary worksheet. My nmon data collection command is "/opt/nmon/nmon12e_aix537 -tdf -s 900 -c 96 -m /opt/nmon_data". I cannot figure out why this is happening.

I've attached a sample of what it looks like.

Hi,

Though NMON utility is widely used to analyse the resource utilisation on AIX servers, IBM does not officially support the same. It seems that NMON doesn't work with Multi-Pathing recognisation thereby doubling the count of actual no of CPUs. Hope I have addressed your query.

Regards,
Viral

Do you mean that MPIO is causing this problem?

Viral,
I think you are wrong in many ways.

1) The problem is Excel - you need to get it to display more digits after the decimal place on that access.
I guess the lower 0.1 is actually 0.05 rounded up as its been told to display just on digit after the decimal point and can't.

2) nmon does support Multi-Pathing and this is nothing to do with the problem.
I think you might mean Multi-threading which nmon supports too!

3) IBM does support nmon - from AIX 5.3 TL09 and AIX 6.1 TL02 onwards as the function is now inside topas but can be run with the nmon command that comes with AIX default install.
And what was wrong with the support I provided for the past 12 years?

Thanks Nigel

Nigel,

You were correct. This was a problem with Excel. The LPARs that I was having this problem with had very small PhysicalCPU values. This caused Excel to display the values in this manner.

Thanks for you help.
