Properties

IsAutoFailover	Gets a value indicating whether the failover mode of the availability group is is Automatic Failover. Accessing this property may result in an exception, so we initialize it seperately. Specifically, if the primary replica is not currently visible, we throw an exception indicating this. This only occurs when accessing this property from a secondary replica that cannot communicate with the cluster store.
IsOnline	Gets a value indicating whether the Availability Group is up. This is true if a functioning primary replica exists for the Availability Group.
NumberOfDisconnectedReplicas	Gets the nubmer of replicas that are not in a "Connected" state
NumberOfNotSynchronizedReplicas	Gets the number of replicas that are not in a "Synchronized" state. Since only synchronous replicas can be in a "synchronized" state, this does not apply to asynchronous replicas
NumberOfNotSynchronizingReplicas	Gets the nubmer of replicas in a "Not Synchronizing" state.
NumberOfReplicasWithUnhealthyRole	Gets the number of replicas that are neither a primary or a secondary in the Availability Group.
NumberOfSynchronizedSecondaryReplicas	Gets the number of synchronous secondary replicas with Automatic Failover mode and Synchronized state.
