We are using the Nagios plugin check_total_procs to check the total number of processes on our servers. The default settings for this that are installed are:
command[check_total_procs]=/usr/lib/nagios/plugins/check_procs -w 150 -c 200
With these settings almost all of our servers are in either a warning (over 150 processes) or critical state (over 200 processes). The servers are all Debian based and are primarily web and database servers.
My question is are those default values a good baseline? Should I worry that most of my servers appear to have over 200 running processes, or for a machine running standard LAMP stack is that pretty normal?
