I want to create an alert that will fire when a VMs disk usage grows rapidly (i.e. 1tb over 24 hours).
I have created a view with this data by creating an expression over 24 hours. It calculates disk usage now minus 24hrs ago.
How would I do the same but to fire an alert when this reaches a certain threshold? I was thinking to create a super metric for disk usage 24 hours ago and alert when the difference is x greater than the current value, but I dont know how to do a time shift for the super metric, or if that is even possible.
