What do you do when you get 5 error notification messages in your email? Do you really read them, or do you delete them and then go to the Events By Date, collapse all, then expand the errors?
If the latter, like me, then it's a strong indication that the individual email notification messages aren't really important, they are effectively just a single vague "hey, look over here" message repeated 5 times.
What I want is a way to answer the question: "Oh, I got 5 error messages, should I concerned?" even before I look in OpenLog.
The best solution I can come up with is a digest option on the notification that will consolidate all related log entries into a single email, subtotaled by database, agent, and error.
