Aggregate data over different time ranges

I end up cloning modules all the time, and yeah it definitely feels like overkill when you have to create a whole new module to do a little thing haha.

Alternatively, on the resource/group level, have you considered either (a) creating a few scheduled, repeating SDTs that will suppress alerts during the times of day you know the disks will be busy? or (b) modifying the "Alert trigger interval" so it'll only alert you if the problem sticks around for more than x polls? or lastly, (c) maybe create a few new alert thresholds that only apply during certain times of the day? 

Without knowing the exact situation, I'd likely look at going one of those directions:)
