We need to be able to display information like database connection pool size (and number of used connections), general database availability, mailserver-availability, database latency, and so on.

We should have this information in the system information page (and provide some explanations) but also provide a JMX interface for easy monitoring.

The documentation for this feature can be found at http://confluence.atlassian.com/display/DOC/Live+Monitoring+Using+the+JMX+Interface
