The Unix server has no issues.

I m not looking to resolve any issue. All i want is to setup a non third part monitoring mechanism to monitor Tomcat Hung state. Unfortunately, all the suggestions be it mine or others is not helpful to print and debug Tomcat v8 hung state.

If anyone knows ... please suggest.
