Is it possible to schedule the maintenance (Index rebuilt) at a specific date/time (e.g. during the night)?
Enhancement request CR 235321 has been submitted to Development for consideration in future release of Performance Analysis for SQL Server.
If the site runs maintenance on all their databases and therefore does not need the maintenance routine to be run in PA (Agent Admin -> Performance Repository -> Maintenance tab), then the PASS maintenance routine should be disabled.
Rather than disabling the maintenance by un-checking options on the maintenance tab (Index Rebuild and Daily Maintenance), the suggestion is to run the following sql against the repository database...set the IS_SELF_CONTAINED flag to 1 in the QUEST_REP_VERSION table:
SET IS_SELF_CONTAINED = 1
which will prevent PASS maintenance from running and the user will be responsible for maintaining the repository db.
