Can anyone provide any suggestions on how I could monitor for a significant change in disk space (free mb) over a 5 Minute period
for example if a server has used 3gb of space within the last 5 Minutes I would want an alert.
I have an idea of using powershell and just repeating the same wmi command with a sleep in the middle then writing an event based on the result of the comparison of the 2 values to be monitored for, yet this just seems like i'm overengineering the situation , any suggestion ?
