Effective Disk Monitoring


Is it possible to create a disk threshold that aggregates multiple conditions before sending an alert?  The scenario I have in mind, is where a disk might be 90% full, which would ordinarily trigger an alert, but due to the size of the disk (say 1TB), there is 100GB remaining.  I would like to be able to build a threshold that allows us to check if a disk is over 90% and has less than 5GB free space remaining, then alert.

Has anyone had any success in doing something similar?

Many Thanks,

Hey Nick,

You should be able to do this with a Complex Datapoint and Datapoint Expressions: https://www.logicmonitor.com/support/datasources/creating-managing-datasources/datapoint-expressions/

Something like:

if( and( gt(StorageUsed, 90), lt(StorageSize, 5) ), 1, 0)

Then just set an alert threshold if that Complex Datapoint returns 1.
