In Windows Server 2012 Release Candidate, Hyper-V administrators can monitor the ‘health’ of the replicating VMs using the Replication Health attribute. This property allows administrators to answer common questions such as:
When did the primary and replica VMs last synchronize?
What is the average size of the replica file?
Were there any errors encountered during replication which requires your attention? etc.
The two-part FAQ post explains the concept of Replication Health and provides guidance on how to interpret the attribute values.
