I leveraged hadoop metrics2 system to inject hadoop metrics in ganglia and these metrics were shown properly in host page. And then, I created a new view and added some default metrics (e.g. cpu_idle) in it. These default metrics were shown properly too in the custom view. However, I met "No matching metrics detected" issue after I added hadoop metrics in custom view. These metrics are something like dfs.datanode.BlocksReportedNumOps which is stored as dfs.datanode.BlocksReportedNumOps.rrd file in disk.
