Hi threre,

Monitoing a JavaEE app server takes lots of steps which depends on application architecture.

For example, you should monitor worker threads for each Tomcat Connector you are using. If all
threads are in use (no iddle thread in pool) user response time will suffer.

Another example, if a deployed application uses datasources, you should monitor availabe connection
in the datasource connection pool, same was as connector thread pool.
