Hi Rui Gao,

Ambari no longer support Ganglia in version 2.1.0. Instead Ambari Metrics Service provides
better capability to scale with regards to growing cluster size as well as customized dashboard
based visualizations using Grafana.

Regarding you question regarding the ports: Is the NN configured to listen on different ports
for clients and datanodes?

hdfs-site :: dfs.namenode.servicerpc-address

Again these settings that you have below:

rpcdetailed.rpcdetailed.client.CompleteAvgTime and rpcdetailed.rpcdetailed.datanode.CompleteAvgTime

are verified to work with AMS backend in 2.2.2 and not Ganglia.

Subject: About Ganglia configuration in

Hello everyone,

Nice to meet you all. I'm Gao, an engineer working in Japan.

I'm using Ambari to deploy Hadoop clusters, and using ganglia to monitor clusters.
In a cluster using Ambari Version, thanks to, we could
got following configurations in of namenodes:

#Namenode rpc ports customization

These configurations help us to monitor the ports respectively in Ambari WebUI as two groups:
 rpcdetailed.rpcdetailed.client.CompleteAvgTime and rpcdetailed.rpcdetailed.datanode.CompleteAvgTime

I want to monitor these ports separately in ganglia, so we add

#Namenode rpc ports customization

#Namenode rpc ports customization(ganglia)

in the testing cluster, which using Ambari Version, but we still can only get the
metrics of one port. And can only get rpcdetailed.rpcdetailed.CompleteAvgTime, not "rpcdetailed.rpcdetailed.client.CompleteAvgTime
and rpcdetailed.rpcdetailed.datanode.CompleteAvgTime" respectively.

I wonder to ask that is there anyone knows how to get separated ports metrics for ganglia
by editing ambari file?
And,  is separated port monitoring can only be possible in Ambari Version and newer
versions, not supported in Ambari Version Or, just I made mistakes about the configuration?

Looking forward to your reply! Thank you very much!

Best regards,
