Jaimin D Jetly updated AMBARI-16139:
------------------------------------
Description:
Graphs on Cluster dashboard page keeps making API calls irrespective of the
previous APIs call have completed or not. Thus on a cluster where AMS is
misbehaving there are multiple same API calls in pending state and results into
ambari-server unresponsive.
For Graph widgets, ajax calls should be made from the complete callback
function of the same ajax call. so until an ajax call is not finished, the same
ajax is not triggered again
we do this in correct way for enhanced service dashboard on service summary
