Class HealthMonitor

java.lang.Object

org.jclouds.rackspace.cloudloadbalancers.v1.domain.HealthMonitor

public class HealthMonitor
extends Object

The load balancing service includes a health monitoring operation which periodically checks your back-end nodes to ensure they are responding correctly. If a node is not responding, it is removed from rotation until the health monitor determines that the node is functional. In addition to being performed periodically, the health check also is performed against every node that is added to ensure that the node is operating properly before allowing it to service traffic. Only one health monitor is allowed to be enabled on a load balancer at a time.

As part of your strategy for monitoring connections, you should consider defining secondary nodes that provide failover for effectively routing traffic in case the primary node fails. This is an additional feature that will ensure you remain up in case your primary node fails.
