The monitoring plugin adds chat archiving support to Openfire together with a neat dashboard and a list of reports.
Copy monitoring.jar into the plugins directory of your Openfire installation. The plugin will then be automatically deployed. To upgrade to a new version, copy the new monitoring.jar file over the existing file.
Make sure that the enterprise plugin is removed before installing this plugin. Otherwise the enterprise plugin will rename the fastpath.jar to fastpath.jar.old thus removing thus plugin. If this happens just stop the server, remove the enterprise.jar plugin and rename fastpath.jar.old to fastpath.jar and start the server again.
