NAME¶

psauxlog - log the process list with timestamp

SYNOPSIS¶

psauxlog [ logfile ]

DESCRIPTION¶

psauxlog logs the process list with timestamp. Basically the script puts the output of "date +%F %T" in front of each line for the output of "ps aux". If more data is needed, pidstat could be the right choice.

EXAMPLES¶

* Run psauxlog every 10 minutes. The crontab entry could look like this:

-04-59/10 * * * * root /usr/sbin/psauxlog /var/log/psaux.log

* Rotate and compress log from time to time. The logrotate entry could look like this:

/var/log/psaux.log {
compress
dateext
maxage 365
rotate 99
size +4M
notifempty
missingok
copytruncate
}

* Show processes waiting on IO. Use default logfile:

# awk '$10~/D/' /var/log/psaux.log

* Show zombie processes. Use default logfile:

# awk '$10~/Z/' /var/log/psaux.log

* Show processes existing at a certain time, e.g. 2021-09-27 07:01. Use default logfile:

# awk '$1~/2021-09-27/&&$2~/^07:01:/' /var/log/psaux.log

* Show when a certain process did exist, e.g sapstartsrv. Use default logfile:

# awk '$13~/sapstartsrv/' /var/log/psaux.log

* Show processes using more than a certain CPU percentage, e.g. 100%. Use default and all compressed logfiles:

# less /var/log/psaux.log* | awk '$5>100'

* Show processes of a certain user using more than a certain CPU percentage. E.g. SAP <sid>adm of SID HA1 using more than 50%. Use default and all compressed logfiles:

# less /var/log/psaux.log* | awk '$3="ha1adm"&&$5>50'
