updateNodeHealth

 DiskHealthInfo diskHealthInfo)

clusterChanged

public void clusterChanged(ClusterChangedEvent event)

Description copied from interface: ClusterStateListener

Called when cluster state changes.

Cluster states are applied one-by-one which means they can be a performance bottleneck. Implementations of this method should therefore be fast, so please consider forking work into the background rather than doing everything inline.

Specified by:

clusterChanged in interface ClusterStateListener

getHealthInfo

public HealthInfo getHealthInfo()

This returns all the health info stored in this cache

Returns:

A HealthInfo object wrapping all health data in the cache
