Summary
Tomcat MBeans are quite useful for monitoring. Normally, they are found under the Catalina sub-tree, but that is not true for Confluence.
This is related to the Engine name set by default on the server.xml file:
1
<Engine name="Standalone" defaultHost="localhost" debug="0">Solution
When looking for those MBeans in the Confluence JMX interface, just expand the Standalone subtree as shown below:
While it should be possible to edit the server.xml file and set a different name, we would not recommend that. This is because other files might reference the engine name, and it also creates another customization to reapply after every upgrade.
