Heartbeat Check

The Heartbeat Check checks to make sure that the platform is still running. It's accomplished by visiting a URL which gets processed by Tomcat. (The URL is very lightweight, does not require a login, and still gets processed by Tomcat.)

https://<yourdomain>/networking/rest

If Tomcat is running, you will get an http return code of 200.

Note: If Tomcat runs out of memory is not responding for some other reason, you won't be able to tell by monitoring the port or the process. The Heartbeat Check is the only way to know.
