2. Planning for Ambari Alerts and Metrics in Ambari 2.0

As part of Ambari 2.0, Ambari includes built-in systems for alerting and metrics collection. Therefore, when upgrading to Ambari 2.0, the legacy Nagios and Ganglia services must be removed and replaced with the new systems.


We highly recommended that you perform and validate this procedure in a test environment prior to attempting the Ambari upgrade on production systems.
