[Nagiosplug-help] [Nagios-users] plugns

[Israel Brewster]

Actually, the behavior as noted is correct- the plugin checks for the  
percentage of free space remaining, not the amount used. So to use  
your example, you would want the command to be /usr/libexec/nagios/ 
check_disk -w 15% -c 5% -p /dev/hda1 since you want a warning when  
only 15% of the drive capacity is avalable, and critical when 5% of  
the drive is free.
