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 this? I am looking forward to hearing from you soon and Best wishes for you！ Sincerely, Feng Song [cid:[email protected]] Ganglia did like this [cid:[email protected]] -- ____________________________ Mobile Communication Lab, Information Theory and Technology Center, School of Information and Communication Engineering, Beijing University of Posts and Telecommunications, Tel:13141376497 Email: [email protected]<mailto:[email protected]> Feng Song ?
