Ted Yu commented on HBASE-20450: -------------------------------- {code} + String NUM_ACTIVE_HANDLER_DESC = "Number of total active rpc handlers."; {code} Number of total -> Total number of The rest looks okay. > Provide metrics for number of total active, priority and replication rpc > handlers > --------------------------------------------------------------------------------- > > Key: HBASE-20450 > URL: https://issues.apache.org/jira/browse/HBASE-20450 > Project: HBase > Issue Type: Improvement > Components: metrics > Reporter: Nihal Jain > Assignee: Nihal Jain > Priority: Major > Fix For: 3.0.0 > > Attachments: HBASE-20450.master.001.patch > > > Currently hbase provides a metric for [number of total active rpc > handlers|https://github.com/apache/hbase/blob/f4f2b68238a094d7b1931dc8b7939742ccbb2b57/hbase-server/src/main/java/org/apache/hadoop/hbase/ipc/SimpleRpcScheduler.java#L187] > which is a sum of the following: > * number of active general rpc handlers > * number of active priority rpc handlers > * number of active replication rpc handlers > I think we can have 3 different metrics corresponding to the above mentioned > handlers which will allow us to see detailed information about number of > active handlers running for a particular type of handler. > We can have following new metrics: > * numActiveGeneralHandler > * numActivePriorityHandler > * numActiveReplicationHandler > > > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
