> *NOTE: Replace HDFS,HBASE, YARN in the above call with the names of all
> installed services in the cluster. This API call is implemented in the
> backend and is currently working on the current trunk bits.
> NOTE: This task needs to be implemented for GAUGE, NUMBER and GRAPH widget
> type. Achieving this for TEMPLATE widget type will be achieved in a seperate
> task
