NMON_Analyser User Guide for V6.0
Preface
NMON_Analyser is designed to complement NMON (Nigel’s Monitor) in analysing and
reporting performance problems; it produces graphs for virtually all sections of output created
using the “spreadsheet output” mode of NMON as well as doing some additional analyses for
ESS, EMC and FAStT subsystems. It will also work with files produced by topasout and with
other tools that produce data in “NMON” format.
For Windows users: It is written using Excel 2016 and shoud work with Excel 2007 or later. It
may work also on Excel 2003 with the required Microsoft updates to support .xlsx files
https://support.microsoft.com/kb/924074?wa=wsignin1.0
For Mac users: It is tested using Excel for Mac 2016. It should work with earlier versions such
as Excel 2011 but has not been recently tested.
Note #1: Recent Microsoft Excel for Mac updates (released in Jan 2019) have broken nmon
Analyzer (prior versions) and users will receive overflow errors. This version is intended to
work around these issues. As a result, some graphs may appear at the top of the sheet instead of
the bottom.
Note #2: If you wish to collect very large nmon files (10+ MB) and attempt to use the NMON
Analyser against them, then you should install 64-bit Microsoft Excel 2013 or 2016. Installing
64-bit Excel is critical or you will likely run out of memory and it will fail. You also need to
have 8 GB RAM and preferably more.
NMON was originally written by Nigel Griffiths (nag@uk.ibm.com) and is now (since AIX 5.3
TL09 and AIX 6.1 TL02) part of topas. NMON_Analyser was originally written by Stephen
Atkins with contributions from many people – including Ralf Schmidt-Dannert and Markus
Fehling, both of IBM. Currently nmon Analyzer is maintained by Ron McCargar
(mccargar@us.ibm.com.)
Support for NMON_Analyser is provided on a best efforts basis. Please direct questions to the
User Forum (see below) rather than contact the author direct.

• Work around added for overflow error on Mac OS when trying to chart graphs on several
sheet like DISK_SUMM. Appears to be a bug with Excel on Mac OS only.
• On Mac OS the graphs were drawn too wide, made a change so by default they are drawn to
consume a more reasonable amount of space similar to how it is done on Windows.
• Fixed graph titles/descriptions for DISKAVGRIO, DISKAVGWIO: they were wrong per AIX
documentation here:

New in V5.5
• Fixed an issue where the DISK_SUMM metrics were wrong if more than 150 disks existed in
the data.
New in V5.4
• When running on MAC, showing progress during the run is much faster now. The
SHOWMACPROGRESS option now defaults to YES. Note: Using SHOWMACPROGRESS =
YES will slow execution somewhat (maybe 30-50% slower) but the benefit is you will clearly know
that the process is not "hung".
• On MACs, fixed batch processing of multiple files related to use of : instead / for subdirectories.
• On Macs, fixed issues relating to merging of multiple files because of usage of : instead of /
New in V5.2.2
• When using the merge function its possible the filename generated may incorrectly contain a :
colon causing the analyzer to fail.
New in V5.2.1
• Tested on Excel 2016: Please note you may experience the following issue “texttocolumns
method of range class failed” a possible work around:
“I installed Excel 2016 on my mac. I open excel , enable macros run the latest analyzer. It fails with
“texttocolumns method of range class failed”. Then i see in the background that the Sheet2 has no data
in column A, i.e. data didn't get copied into Excel from the .nmon file. I put in a 1 into first cell of column
A (could add any data really to avoid the error) and hit the button to continue. Then it fails like it should
saying "no valid nmon data".
I shut down Excel and I came back in again later rerun the analyzer and I did not get the problem it
seemed like a 1 time thing, it ran through it successfully. Tested it a few more times, it doesn’t happen
anymore. Uncertain what caused this to fail the 1
st
time but FYI“
New in V5.2
• Add Merge support when running on a Mac.
New in V5.12
• Fixed problems if running on Mac Excel 2016
