I am trying to figure out a way to alert on say the % disk space available but only create the alert if it has changed by X percent over a specific time period
so say a server was sitting at 50% of its C:\ drive used and if over the last 24 hours it jumped up to 75% used i would want to know that a massive change occurred. however if the same server increased to 75% but it took a year to get there that's just normal utilization.
