Dear Siddharth Wagle,
       Sorry to take your time to answer my question.
       Would you please tell me how to add a host metrics widget at the marked space of the
following picture? As you know, If some problems occurred in the cluster, I need to figure
out the causes quickly, so I need to see some information such as the disk_io, If the host
has a component RegionServer,   I may want to see the the RS_rpcScanRequestCount widget  just
as the Ganglia did. If the host has a component DataNode, I may want to see some important
widget related to the DataNode at the marked space of the following picture. How can I do
       I am looking forward to hearing from you soon and Best wishes for you!
      Feng Song
