Modify the service metrics dashboard
Useto scan metrics data for services that display metrics.
Depending on the service, the Metrics tab includes widgets populated by default with important service metrics information to monitor:
If you have Ambari Metrics service (AMS) installed and are using Apache HDFS, Apache Hive, Apache HBase, or Apache YARN, you can view a Metrics dashboard for that service. You can add and remove widgets from the Metrics dashboard, and you can create new widgets and delete widgets. Widgets can be private to you and your dashboard, or they can be shared in a Widget Browser library. You must have AMS installed to view Metrics for AMS service.
