I used high availability synchronous mode for db mirroring.I used one single box for doing db mirroring across three sql instances for principal,mirror and witness server.It worked fine,no issues.
When I went to check some of the counters on mirror instance from my perfmon it did not show any activity at all.Althogh the snapshot creataed against mirror db showed updated records but mirror counters such as Sql server:sql2k8:database mirroring log bytes received/sec and many mirror related counters,no activity was seen.what could be the problem?can anyone explain.
