Subject [jira] [Created] (AMBARI-6400) Extra gmond processes
Date Mon, 07 Jul 2014 15:06:34 GMT
Dmitry Lysnichenko created AMBARI-6400:
------------------------------------------

             Summary: Extra gmond processes
                 Key: AMBARI-6400
                 URL: https://issues.apache.org/jira/browse/AMBARI-6400
             Project: Ambari
          Issue Type: Task
          Components: controller
    Affects Versions: 1.6.1
            Reporter: Dmitry Lysnichenko
            Assignee: Dmitry Lysnichenko
             Fix For: 1.7.0


Ambari starts gmond processes associated with various host components on the host they are
running even if the host is not a ganglia server host.

For example, on the host that has HBase RS and Yarn RM you will see
{noformat}
nobody   27892  2.1  0.0  59020  1800 ?        Ssl  21:22   0:06 /usr/sbin/gmond --conf=/etc/ganglia/hdp/HDPHBaseRegionServer/gmond.core.conf
--pid-file=/var/run/ganglia/hdp/HDPHBaseRegionServer/gmond.pid
nobody   27911  2.1  0.0  59020  1772 ?        Ssl  21:22   0:06 /usr/sbin/gmond --conf=/etc/ganglia/hdp/HDPResourceManager/gmond.core.conf
--pid-file=/var/run/ganglia/hdp/HDPResourceManager/gmond.pid
{noformat}

However, this host is not the ganglia server host so these gmond processes are not required.

*hbase ganglia config*:
hadoop-metrics2-hbase.properties:hbase.servers=c6401.ambari.apache.org:8660
hadoop-metrics2-hbase.properties:jvm.servers=c6401.ambari.apache.org:8660
hadoop-metrics2-hbase.properties:rpc.servers=c6401.ambari.apache.org:8660
hadoop-metrics2-hbase.properties:hbase.sink.ganglia.servers=c6401.ambari.apache.org:8660

*yarn ganglia config*:
hadoop-metrics2.properties:resourcemanager.sink.ganglia.servers=c6401.ambari.apache.org:8664

Also fixed storing HBase RS metrics in wrong rrd directory
