Nmon Analyser User Guide For V3.4

NMON_Analyser User Guide for V3.4

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 andwith other tools that produce data in “NMON” format. It is written in VBA for Excel and will work with Excel 2003 or later.

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.

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.

Collecting data using NMON

Please make sure you have the latest versions of both NMON and NMON_Analyser before starting a new engagement. If you want automatic notification of a new release of the Analyser send a note to steve_atkins@uk.ibm.com and I’ll add you to my distribution list. Nigel maintains a similar list for NMON.
