title: Customize WebLogic's heartbeat message
body: <p>I'm currently developing a system to ensure high performance, availability and scalability; fail-over and crash recovery on a WebLogic integration scenario.</p>
  
  <p>Does anybody know if it is possible to customize WebLogic's native heartbeat messages, to add some additional information such as current CPU usage and/or network load?</p>
  
  <p>The purpose is to allow load-balancing algorithms that use that "custom" information, to avoid overloading a struggling server with more requests.</p>
