Weiwei Yang created HDFS-12684: ---------------------------------- Summary: Ozone: SCM metrics NodeCount is overlapping with node manager metrics Key: HDFS-12684 URL: https://issues.apache.org/jira/browse/HDFS-12684 Project: Hadoop HDFS Issue Type: Sub-task Components: ozone, scm Reporter: Weiwei Yang Priority: Minor
I found this issue while reviewing HDFS-11468, from http://scm_host:9876/jmx, both SCM and SCMNodeManager has {{NodeCount}} metrics {noformat} { "name" : "Hadoop:service=StorageContainerManager,name=StorageContainerManagerInfo,component=ServerRuntime", "modelerType" : "org.apache.hadoop.ozone.scm.StorageContainerManager", "ClientRpcPort" : "9860", "DatanodeRpcPort" : "9861", "NodeCount" : [ { "key" : "STALE", "value" : 0 }, { "key" : "DECOMMISSIONING", "value" : 0 }, { "key" : "DECOMMISSIONED", "value" : 0 }, { "key" : "FREE_NODE", "value" : 0 }, { "key" : "RAFT_MEMBER", "value" : 0 }, { "key" : "HEALTHY", "value" : 0 }, { "key" : "DEAD", "value" : 0 }, { "key" : "UNKNOWN", "value" : 0 } ], "CompileInfo" : "2017-10-17T06:47Z xxx", "Version" : "3.1.0-SNAPSHOT, r6019a25908ce75155656f13effd8e2e53ed43461", "SoftwareVersion" : "3.1.0-SNAPSHOT", "StartedTimeInMillis" : 1508393551065 }, { "name" : "Hadoop:service=SCMNodeManager,name=SCMNodeManagerInfo", "modelerType" : "org.apache.hadoop.ozone.scm.node.SCMNodeManager", "NodeCount" : [ { "key" : "STALE", "value" : 0 }, { "key" : "DECOMMISSIONING", "value" : 0 }, { "key" : "DECOMMISSIONED", "value" : 0 }, { "key" : "FREE_NODE", "value" : 0 }, { "key" : "RAFT_MEMBER", "value" : 0 }, { "key" : "HEALTHY", "value" : 0 }, { "key" : "DEAD", "value" : 0 }, { "key" : "UNKNOWN", "value" : 0 } ], "OutOfChillMode" : false, "MinimumChillModeNodes" : 1, "ChillModeStatus" : "Still in chill mode, waiting on nodes to report in. 0 nodes reported, minimal 1 nodes required." } {noformat} hence, propose to remove {{NodeCount}} from {{SCMMXBean}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
