AIX nmon Recipe

1. Start nmon with a 60 second interval:

   nohup nmon -fT -s 60 -c 1000000 -o diag_nmon_$(hostname)_$(date +"%Y%m%d_%H%M%S").nmon

2. Reproduce the problem.
3. Stop nmon:

   ps -ef | grep diag_nmon | grep -v grep | awk '{print $2}' | xargs kill -USR2

4. Upload *.nmon and nohup.out

Notes:

• NMONVisualizer is a common tool to analyze nmon files. Note that AIX nmon defaults to the local timezone (unless -G is used for UTC), so the local time zone should be selected when loading in NMONVisualizer.

For background, see AIX nmon.
