Class LocalHealthMonitor

java.lang.Object

org.elasticsearch.health.node.LocalHealthMonitor

All Implemented Interfaces:

ClusterStateListener

public class LocalHealthMonitor
extends Object
implements ClusterStateListener

This class monitors the local health of the node, such as the load and any errors that can be specific to a node (as opposed to errors that are cluster-wide). It informs the health node about the local health upon change, or when a new node is detected, or when the master node changed.

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.
