Class HealthMonitor

Active health monitoring is a technique that uses synthetic transactions executed at periodic intervals to determine the condition of a node. One of the advantages of active health monitoring is that it does not require active transactions to be processed by the load balancer to determine whether or not a node is suitable for handling traffic. Active health monitoring is not applied by default and must be enabled per load balancer.

The active health monitor can use one of three types of probes:

connect
HTTP
HTTPS

These probes are executed at configured intervals; in the event of a failure, the node status changes to OFFLINE and the node will not receive traffic. If, after running a subsequent test, the probe detects that the node has recovered, then the node's status is changed to ONLINE and it is capable of servicing requests.
