Hi,
I am wondering if it was possible to create an alert that will trigger if the volume (hard disk) utilisation increases by X percent over Y time? E.g. 20% over 2 hours.
I have created the following custom alert in the advanced alert manager. It should trigger when the utilisation changes by 5% in less than a 2 hour window but it does not. I tested this by monitoring a local volume, then copying files on the disk to increase the utilisation percentage (43% to 60%). Running the query against the database returns the volume that I am testing against but still no alert (action is to send an npm event and write to a local log file).
(I also believe the alert will trigger if the utilisation DROPS over time as well but that's something to sort out if I can get this step working...)
Does anyone have any experience with a volume delta alert or can see where my SQL alert is incorrect?
(Alert is enabled, set to check every 1 minute, reset when no longer true, trigger all times of day)
Thanks
