Monitoring Service @ Openfire 3.6.4 and Active Directory

I am getting the following lines in console

Missing database schema for monitoring. Attempting to install…
monitoring - Database update failed. Please manually upgrade your database.
Starting Monitoring Plugin

It seems the plugin is logging the count of messeges but not the content of messeges, as on searching no result is found
