I have a several different Jobs that fail periodically, once in a while is not a big problem but when they continue to fail over a period of time it does become a problem and I need to know. Likewise when I have an AG is slow to sync in the middle of the night when it is rebuilding all of the indexes of a 1.2TB database and syncing across to locations in 2 states I don't want to be paged, but if it is persistent through the day I do.
