For example i have a rule that verifies the size of the swap, but I need to see if the growth was gradualy or if it was in the last 15 minutes. I have a series of applications that use a lot of swap space, but to be a problem for me it will be determined by if this growth of the used swap was in the timeframe of the last 15 minutes.
In Appmon I don't know about option of monitoring size of change in time, not whole value. I think you will have to create dashboard and check charts from time to time. Even business transaction will not help here.
