I have a wmi component, let it be "Queue Length" with 3 min poll interval.
And I have a threshold for it "Length>500". So every time it cross a threshold line, I get an email.
I want to make other alert to see a dynamic/trend of the queue length.
It must be like "if current queue length is bigger than 3 minutes ago - send an email".
Is it possible to compare current component value with previous?
