False alarms monitoring disks
« on: October 19, 2018, 03:29:37 pm »
I am monitoring a numebr of disk on Windows file servers.  I have set a low disk space threshold of < 5% free space (for last 10 polls) and a no disk space threshhold of <1% (for last 10 polls).  Occasionally I will get an alarm that disk space is low (it will give a value of 1000% or more).  When I check the actual values for the last couple of days they are all above 9%.  After these events I do not get a deactivation event occuring (even though the value is greater than the threshold) so I have to terminate the alarm manually.    Anyone got an idea what may be causing this?

I am monitoring the FileSystem.FreePerc DCI metric.

Misconfiguration on my part. Inother DCI was using the same event.
