* 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.
