      Description

      I have created a simple event recorder that can be used for understanding what happens at the OSGi level at startup or when updating/restarting bundles components.

      The recorder displays a timeline of OSGi events using a console plugin at http://localhost:8888/system/console/OSGiEventsRecorder, which can be useful for profiling system startup at the OSGi level.

      I'll commit the first version to contrib/extensions/event-recorder, feedback and comments are welcome.

        In case someone stumbles on this and wonders why that module is not in Sling's code repository anymore, we moved it to the org.apache.felix.webconsole.plugins.event bundle at http://svn.apache.org/repos/asf/felix/trunk/webconsole-plugins/event/

        I just wrote a blog post at http://grep.codeconsult.ch/2013/10/18/simple-startup-profiling-of-osgi-applications/ about how to use it for startup timing profiling.
