Jetty version
9.4.30

Description
While the HttpChannel.Listener is very powerful, it doesn't have visibility into Servlet/WebApp specific concepts to aide in tracking performance behavior within specific Servlet/WebApp components.

Introduce a Listener (or two) that will :

  • expose startup timing. (overall WebApp timing, and ServletContext specific init timing)
  • expose individual component init timing (for Servlet / Filter / Listener inits)
  • expose WebApp configuration timing (for Configuration steps that can often take a long time to process. eg: annotation/bytecode scanning, jndi/datasource setup, etc)
  • expose tracking of Enter/Exit for Filter.doChain() and Servlet.service() call events.
