It is possible that host components, such as HBASE_REGIONSERVER, DATANODE are not able to push metrics to Ganglia.
Can you check if /var/lib/ganglia/data on the Ganglia metad Server host to see if metrics files are being created? You can also check /var/log/messages on the machines where host components are running. ________________________________ From: Dimitris Bouras <[email protected]> Sent: Friday, March 13, 2015 6:21 AM To: [email protected] Subject: Ganglia metrics on HDP2 Setup with Ambari 1.7. Hi, I have successfully set-up HDP 2.2 using Ambari 1.7 on Centos 6.5. I have done this using ec2 instances. However when I select the GangliaUI I only see the option to select the node Ganglia is installed on. All other machine are running gmond. My gmetad file hase the following datasourses registered by default data_source "HDPSlaves" ip-10-200-0-101.ec2.internal:8660 data_source "HDPNodeManager" ip-10-200-0-101.ec2.internal:8657 data_source "HDPNimbus" ip-10-200-0-101.ec2.internal:8649 data_source "HDPResourceManager" ip-10-200-0-101.ec2.internal:8664 data_source "HDPKafka" ip-10-200-0-101.ec2.internal:8671 data_source "HDPHBaseRegionServer" ip-10-200-0-101.ec2.internal:8656 data_source "HDPDataNode" ip-10-200-0-101.ec2.internal:8659 data_source "HDPNameNode" ip-10-200-0-101.ec2.internal:8661 data_source "HDPHBaseMaster" ip-10-200-0-101.ec2.internal:8663 data_source "HDPSupervisor" ip-10-200-0-101.ec2.internal:8650 data_source "HDPHistoryServer" ip-10-200-0-101.ec2.internal:8666 Am i missing some configuration in order to enable other nodes in my cluster? Thanks
