We are running a HA env with 3 app servers behind the Apache.
We are using mod_jk and JKWorkerProperty to set up the load balancing in httpd.conf as provided in the Appian documentation.
Issue is, we notice that whenever one of the tomcat servers are down, requests are still routed to the instance. This doesn't happen when entire instance is down.
I assume Apache is doing a basic TCP to determine the health of the backend server.
I want to know if I can configure a tomcat health check GET url in my Apache config to determine the health of the instance from apache?

I think this we can do it but not sure whether it will work by this way or you can try creating web api for tomcat heat check than you can use that web api.
