A failed ping is a ping to the primary database that failed or took longer than the
time specified by the ObserverPingInterval property. You must set
both the ObserverPingRetry and
ObserverPingInterval properties to achieve lower detection
times for primary database failures. The minimum value of
ObserverPingRetry is 10. Therefore, the detection time can be
reduced to nearly 1 second.
The FastStartFailoverThreshold property is ignored when
the ObserverPingRetry and ObserverPingInterval
properties are set.
