All Implemented Interfaces:

RoutingDataRepository.RoutingDataChangedListener

public class AggPartitionHealthStats
extends AbstractVeniceAggStats<PartitionHealthStats>
implements RoutingDataRepository.RoutingDataChangedListener

Monitor the change of Helix's external view and warn in case that any partition is unhealthy. E.g. if the number of replicas in a partition is smaller than the required replication factor, we would log a warn message and record to our metrics.
