====== Scripts to collect perf ======

===== NMON example =====

NMON is natively integrated to AIX OS, so you can also use it to collect perf evey 30 seconds and count of 2880, so for 24 hours. When finish, you can use the .nmon file and analyse it with NMON analyser (excel)
<cli prompt='>'>
root@prod /var/nmon> crontab -l
01 0 * * * /usr/bin/nmon -fTNWLAd^ -m /var/nmon -s30 -c2880 > /dev/null 2>&1
</cli>

===== ps, pb memory per process example =====

<cli prompt='>'>
root@prod /var/nmon> crontab -l
