The default filesystem discovery has a basic warning for filesystems that is 20% or less free space, produces a warning. I'd like to create individual triggers for some filesystems that have different thresholds (based on the mountpoint), and send alerts to different email addresses depending. Can anyone give me the basics of how I might go about that? I can see how to change the 20% number in the template, but I need to differentiate them more than that. Thanks in advance for any tips!
