We have a need to automatically failover traffic between PROD and DR Gemfire clusters.
We are planning to implement lightweight Spring Boot Gemfire client app which will be monitored by F5 load balancer. Say these apps expose a REST endpoint which say "UP" or "DOWN" depending on weather Gemfire cluster is actively serving requests. One way we are thinking of implementing "Health Check" app is to handle NoAvailableServersException. I believe this will only cover the scenario where all the servers are down. We wanted to know, list of failure scenarios to be handled in Gemfire client to determine whether cluster is running or not. We wanted to check with community if any one has implemented Health Check styled apps for Gemfire cluster and can share insights with us.
