It would be great to be able to set exclusion times such as the "maintenance windows" when index maintenance activities take place such as every day between 12pm-2am in our case. During these times disk queue length will be predictably high due to the maintenance activities taking place.
When viewing graph analysis for a 28 day period for disk queue length you see peaks which are from the maintenance activities and these events end up skewing the overview of BAU activity.
It would be great to be able to define an "exclusion time window" in the analysis report window to exclude any graph data of those periods and provide an trend line based on that. I've attached 2 images, one showing what currently shows over a large timespan, and the second showing an improvised graph whereby the regular peaks (out of hours) are omitted showing a more reflective business hours behaviour.
