It would be great if ArcGIS Monitor allowed us to configure planned maintenance hours (service windows) when no alerts should be sent.
E.g. we know that our database is backed up every evening at 7 p.m. Database CPU usage will grow to more than 85% and trigger an alert email. This notification is not necessary as we know that the DB is under heavy load every evening at 7 p.m. The notification potentially distracts us from real problems.
