Nagios Support Forum

I am running the 60day VM edition of nagiosxi with about 6 windows hosts and about 40 monitored services. On two of my servers I have frives that are constantly being used that run about 96-99% full so of course they always show critical. Is there a way to set it up so that I can be warned when the free disk space goes below 3GB of space available?
Thanks

This sounds like a good use for some of the advanced threshold options that you can define in your commands, or your service definitions for warning and critical thresholds. You would change these through Configure > CCM > Services > "Service Name":

You would want to be looking at Table 4 from the above link.
