This project is a community driven fork of Lambda Probe. You just download it from and deploy it to Tomcat.

In order to access this application you have to edit tomcat-users.xml file

<?xml version='1.0' encoding='utf-8'?>
  <role rolename="manager"/>
  <role rolename="tomcat"/>
  <role rolename="admin"/>
  <role rolename="role1"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="admin" password="admin" roles="admin,manager"/>
  <user username="role1" password="tomcat" roles="role1"/>

Then you can see:

  • Active Sessions
  • Running Threads
  • Memory Utilization (if you add the jmx options to java_opts you can see detail memory graphs)

and much more
