#3 TOP info missing for NMON on LINUX

v1.0 (example)

We have been using NMON for years with AIX. Now we have an application that is being converted to Redhat Linux on intel.

(1) When executing the Analyzer there is a message appearing –

       Replace existing definition of x86?

It appears 8 times. There are no difference in the results if you reply yes or no to the question.

(2) There is a message from Microsoft Visual Basic – Run-time error ‘9’ Subscript out of range.
It is possible to hit end and continue to produce the charts.

(3) Numerous charts do appear including memory/IO etc. However some tabs are missing such as sys-summary, TOP and UARG. The TOP is the most important. It is documented as available. It does appear online.

The Realtime NMON display seems to be ok. However when we run the Analyzer with the NMON datafile we see that various tabs are missing from the report.

We are missing the first tab(System Summary), TOP, UARG and more. The TOP tab is the most valuable info that we want to get from NMON for Linux .

The TOP info does display in the online realtime display. We have tried using -t and -T. However, before debugging any Analyzer issues we notice that the NMON data file from the collector seems to be missing various lines.

For example there are no lines in the data that start with TOP! We are using RHEL 5.8 linux servers and version 14i for NMON.

The first question is whether it is possible with NMON on Linux to get the TOP information output to the file to go to the Analyzer?

If it's possible then the second question is what might cause the loss of TOP and info for other analyzer tabs to be excluded from the collector output file?

Any suggestions will be greatly appreciated as we are depending on getting the NMON TOP info for our Linux servers.

    Hi, Looks like you have tried all the obvious and you are using up to date version so full marked there. Can you state what version of Excel/Microsoft Office you are running and I will take a look. The attached nmon file does not have any TOP data. Could we have one?
    Note the memory stats of AIX and Linux are very different and some information is simply not available. RHEL5.8 is getting on a bit :-) I am using mostly RHEL 7 now.

    Just loaded this file in to excel 2003 - I got the x86 warning but otherwise OK. I assume you are running a higher level that has problems - thanks Mr Gates for not being backward compatible with yourself. There are lots of comments on that and some hints on fixing it.

    I checked your nmon parameters - Oh dear. The docs clearly say -f or -F have to be the first parameter as that pre-sets loads of flags then you can add others.
    nmon -s 60 -c 3600 -XT -F /var/log/nmonlog/vssapptst01_022814_000101.nmon
    should be
    nmon -F /var/log/nmonlog/vssapptst01_022814_000101.nmon -s 60 -c 3600 -XT

    Cheers Nigel Griffiths
