Since the last update on this topic was posted in 2006 I thought I’d bump this to see if 5.8 has a solution for this.
I’m trying to figure out if I can put some type of alert on the recovery DB where if it exceeds a given count of messages in the DB an alert is triggered. Please note, I do not want an alert for each thread but instead just want one for the whole recovery DB which would indicate that our whole engine is slowing down. (or extreamly busy)
