> 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
> behaving 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
> page
