Problems Excluding downtime from checks & notifications

Has nobody else really not experienced this issue?

Please provide some insight. This is quite frustrating, when we have downtimes excluded from our service monitoring rules, but are still receiving warning notifications for events that occur during those down times.

I am starting to receive negative feedback from both management and the team members who are the recipients of these messages because I am unable to prevent them…when we know the events are the direct result of unavailable services during the server reboot process.

I would really appreciate any guidance that anybody can give as to how to prevent warnings from registering, or at least avoid receiving notifications for those events when they do occur.

Thank you in advance for any assistance you might provide.
