Class NetworkHealthCheck

java.lang.Object

org.apache.activemq.artemis.core.server.ActiveMQScheduledComponent

org.apache.activemq.artemis.core.server.NetworkHealthCheck

All Implemented Interfaces:

Runnable, ActiveMQComponent

public class NetworkHealthCheck
extends ActiveMQScheduledComponent

This will use InetAddress.isReachable(int) to determine if the network is alive. It will have a set of addresses, and if any address is reached the network will be considered alive.
