Hi Ming, NN sends metrics to gmond running on the *Ganglia server* host.
Ambari, configures the /etc/ganglia/hdp/<packages> automatically, can you restart Ganglia service and check if there are errors in the agent log. Check, ps aux | grep gmond, on ganglia host, also check the debug log after restarting hdp-gmond service. -Sid On Mon, Oct 20, 2014 at 11:00 PM, Mingjiang Shi <[email protected]> wrote: > Hi Siddharth, > Thanks for your reply. > > I checked the namenode machine, it doesn't have HDPNamenode related > gmond.
