SQL 2012 Always On Redo Rate

by May 15, 2014

We are monitoring SQL 2012 Always On instances and found that lower utilized databases report the Redo Rate in the range less than 100 KB/sec for the Secondary replica. This is causing an alert in Idera DM. We believe the alert has value, however, we believe if it were to take into account the Primary’s send rate it be more valuable. That would reduce the false positives.
