The Pubsub Server Info plugin provides a way for Openfire to report statistics about itself in a well-known pub-sub node: 'serverinfo'. The data format is defined in XEP-xxxx: PubSub Server Info.
Note: at the time of writing, the protocol as implemented by this plugin has not yet been accepted for consideration or approved in any official manner by the XMPP Standards Foundation, and this document is not yet an XMPP Extension Protocol (XEP). This plugin should be considered experimental.
Copy pubsubserverinfo.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 pubsubserverinfo.jar file over the existing file.
