I create a new openfire plugin, called ServerInfo.
ServerInfo provides session information (total users, online users, incoming servers sessions) and you can use this data to create graphs in MRTG or to create alarms in zabbix, nagios, centreon, etc… New resources will be available in future releases.
I invite all of you to download and test the plugin.
You can find the release note here: http://www.mundoopensource.com.br/novo-plugin-para-openfire-serverinfo/ (portuguese only).
