I have to get report Down Time Summary per month for selected monitors...(Admin>Enable Reports>Down Time Summary Reports)

Please see the below pictures..

Please do not make quick decisions, if you write query i think its will be work..

Firstly create query for these report (all of monitors and monthly) than filter for "like windows" "ISDATE" and i will edit manually reason and its will be affects here..

A really down servers and planned (scheduled) down servers reports times are separate times.. Right ?
