I'm newbie to ambari,so I'm reading some articles about it
in one of these articles it's said that :
ambari dashboard is used to give information issued from Ganglia and Nagios
so I wonder if ambari use, or based on Nagios to monitor it's services, if not does it possible to use nagios to monitor ambari (and it's services ) ?
Nagios and Ganglia were used as standalone services, to provide info for Ambari 1.7.0 and less. Since version 2.0, Ambari moved to use his own monitoring service Ambari Metrics and Ambari Alerts. Support of Nagios with Ganglia was dropped.
