How to Capture System Performance Logs on IGEL OS and View in Excel

Written by David Seeber, IGEL Community INSIDER

Recently, IGEL Community INSIDER, David Seeber shared a post inside the Community on Slack detailing how to capture system performance logs from IGEL OS and allow you to view them in Microsoft Excel.

"Just a quick one that I'm throwing out here.

See attached:

  • nmon is a standalone binary that will dump system performance into .nmon file

  • xlsm file is used to open and convert the nmon log to an Excel file with automatically generated charts

How to use:

  • Copy nmon file into IGEL OS, e.g. /wfs/ directory – ensure to append this path to the beginning of the command each time you run it, e.g. /wfs/nmon

  • Execute /wfs/nmon -f for the duration you require, e.g. nmon -f -s 5 -c 200 will run every 5 seconds and capture 200 entries (=1000s total capture time) (or run nmon -f -x to record 1 day's worth or nmon -f -X for 1 hour's worth of captures) N.B: For detailed usage see nmon Command - IBM Documentation.

  • Retrieve the xxxxxx.nmon dump file from IGEL client (will be in the working directory where you were when you ran the command)

  • Open the nmon analyser v66.xlsm and import the xxxxxxxx.nmon dump file (ensure that Editing and Macros are both allowed inside Excel)

  • The macros will ask you to save as a new Excel file and this will contain all the data. For any chart you can scroll up to find the raw data used."
