Subject Re: Graphs and HeatMaps are Not Visible on Ambari Web-UI
Date Mon, 23 Jun 2014 15:16:34 GMT
Hi Meghavi,

Based on this message, GangliaPropertyProvider:456 - Ganglia server
component is not live

It seems the amabri agent is not running on the Ganglia server host.
This message indicates the status of the Ganglia host is HEARTBEAT_LOST.

-Sid
