Heartbeat Check

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.
