HealthMonitoring

@@ -1 @@
-The Metrics library(http://metrics.codahale.com/) by Yammer has excellent support for monitoring the performance and health of a system.  It provides a consistent API for developers to register some vital statistics of an application.  For example in Geonetwork we might want to have a monitor system (like nagios or statd) check the health of the system which would include checking the database connection, ability to open files, check the index, etc...  In addition we might want to attach a Metrics appended to the logging to track the number of errors being logged and the monitor system would be able to warn of a potentially unstable system based on the number of errors being logged.

 Metrics has 2 Apis, one for configuring the health checks and another for performing the configured health checks.  The 'out' Apis include JMX, JSON as well as HTML pages that could be integrated into the admin user interface.
