Alert Rule to monitor when storage usage drops

Hello Everyone,

I am trying to create an alert to notify me when a servers storage usage drops more then say 10%. For example, say I have a volume that is 70% full and suddenly it drops to 45% full. I would like to get an email alert about that.

Yes, this actually happened but it was intentional.

We don’t track previous values so can’t do this.

We probably should though…
