Project Notes

This plugin is written in Python (no 'special' modules needed, just optparse and sys) and parses the output of /proc/meminfo. Unlike some other plugins that check memory, this one also takes cached memory into consideration and adds that to the available FreeMem. This plugin doesn't take Swap memory into consideration. There are other plugins that do that and IMHO if the hosts starts to swap, there's already a problem. This plugin correctly reports Nagios plugin check results. For a quick description use the plugin from the commandline: ./check_mem.py --help

Works but got minor issues

by: raptor

if int(options.crit_threshold) >= int(options.warn_threshold):
print "UNKNOWN: Critical percentage can't be equal to or bigger than warning percentage."

Should it not be the opposite?
