We have a 3 hr window overnight where we don't want to send any alerts or show any downtime for a bunch (>100) of https monitors we have attached to a fake node. I've set up the Unmanage Scheduling Utility to unmanage this node, and then remanage it at the end of the maintenance window. So far, that piece of it seems to be working fine. The problem is that when it remanages the monitors, I get an alert for each saying that they are now "up". Now, I could just configure the alert to not send any "up" alerts for a period after the window expires. The problem is that the remanage process takes 30 minutes to bring everything back up into a green state, and that window is a little longer than I would like.
Is there something I can tune to make it bring things back online a little faster?
Is there a way to stop up alerts being sent when something is remanaged, but to send them for any other case of something transitioning to an up state?
Is there a better way of doing this, or is the Unmanage Scheduling Utility the only way?
