An MBean section for Federated repositories is available whose attributes are identical to the metrics specified in Federated Repository Metrics. The attributes include:
MaximumLagInMs
NumberOfDisabledFederationMembers
NumberOfReposExceedingLagThreshold
This metric requires the use of the Get Federation Mirror Lag Time API to limit the results to those repositories that exceed a defined threshold.
