HealthCheck for Reference

TIBCO API Exchange Gateway provides HealthCheck for Reference functionality to monitor the availability of the target operations in a target operations group.

The Load Balancing Router component of the TIBCO API Exchange Gateway uses the HealthCheck for Reference functionality when it routes an operation request to a target operation group.

TIBCO API Exchange Gateway supports the HealthCheck for Reference functionality for the following types of target operation group:

  • RoundRobinWithFailover
  • WeightedRoundRobinWithFailover

When a facade operation request is routed to a target operation group of the RoundRobinWithFailover or WeightedRoundRobinWithFailover type, the Load Balancer Router of the gateway uses HealthCheck for Reference to check the health of the target operations configured in the target operations group. If the selected target operation is not available or running, the gateway forwards the request to an alternate target operation that is running.

Using the HealthCheck for Reference functionality, the router component of the gateway intelligently picks the available target operation. This increases the throughput and reduces the latency of the request processing at runtime.

Note: The HealthCheck for Reference functionality is available to the Gateway Load balancer Router component to monitor the health of target operations in a target operations group with failover routing algorithms only (RoundRobinWithFailover or WeightedRoundRobinWithFailover).
