Mikhail Stepura updated CASSANDRA-5084: --------------------------------------- Attachment: trunk-5084-native.patch Patch for the native interface. Exported {{ConnectionsCount}} attribute and {{listConnections}} operation via JMX > Cassandra should expose connected client state via JMX > ------------------------------------------------------ > > Key: CASSANDRA-5084 > URL: https://issues.apache.org/jira/browse/CASSANDRA-5084 > Project: Cassandra > Issue Type: Improvement > Reporter: Robert Coli > Assignee: Suresh > Priority: Minor > Labels: lhf > Attachments: trunk-5084-native.patch, trunk-5084.patch > > > There is currently no good way to determine or estimate how many clients are > connected to a cassandra node without using netstat or (if using sync thrift > server) counting threads. There is also no way to understand what state any > given connection is in. People regularly come into #cassandra/cassandra-user@ > and ask how to get the equivalent of a MySQL "SHOW FULL PROCESSLIST." > While I understand that feature parity with SHOW FULL > PROCESSLIST/information_schema.processlist is unlikely, even a few basic > metrics like "number of connected clients" or "number of active clients" > would greatly help with this operational information need. -- This message is automatically generated by JIRA.
