Debugging
HTTP session debugging
For HTTP session related issues, check:
- The contents of the sessions
- When the sessions are created
- What attributes are added/removed
SessionDebugger class to assist with this process. The SessionDebugger class is both a javax.servlet.Filter and an HttpSessionListener. To enable the filter, register it in Magnolia's filter chain. To enable the session event listener, add the following to your web.xml:
<listener> <listener-class>info.magnolia.debug.SessionDebugger</listener-class> </listener>
Warning
This listener logs a large quantity of data in WARN mode. Be sure to disable this process when the debugging session is over.
JCR session monitoring
Magnolia CMS includes a simple JMX Mbean which allows you monitor currently opened JCR sessions. Connect to your container (for instance using JConsole) and locate theMagnolia JCRStats MBean. It will show you how many JCR sessions are currently open. See Monitoring for more.
