Hi Scott, 1.) If optimizing and reclaiming overallocated resources, it will put it back into the capacity pool.  2.) Privileges in vSphere are required in order to perform optimization tasks:  Datastore > Browse datastore Datastore > Remove file Sessions > View and stop sessions Virtual machine > Configuration > Change CPU count Virtual machine > Configuration > Change resource Virtual machine > Configuration > Memory Virtual machine > Interaction > Power Off Virtual machine > Interaction > Power On Virtual machine > State > Remove Snapshot  3.) Out of the box, it will show the Peak Utilization over a 30/60/90 day period (30 days by default). It will not show exactly when that occurred, unless you graph it out beforehand, where you set the time frame to a longer period and look at the peak CPU/memory Utilization.  4.) It will make recommendations immediately. For fresh installations, we recommend waiting 30 days before implementing any recommendations. That is configurable to 30/60/90 days. It is in the Settings link. For an existing customer, you can implement immediately, since that data has been collecting all along.  Kevin
