Hi all, I have configured some Mirroring alerts based on Micosoft's documents. & i went through Satya's slideshow on Mirroring. If you can help me in setting some of the "Thresholds" for the Mirroiring alerts. That will be helpful, because i didnt see anywhere about the actual threshold limits setting for alerts ( In Production). Any approx. also OK. At Principal: (a) Unsent Log = ------ KB (b) Oldest Unsent Transaction = ---- Minutes At Mirror: (c) Unrestored Log = ---- KB. (d) Mirror Commit Overhead = --- MilliSeconds Thanks again.
