Subject [jira] [Created] (ZOOKEEPER-2933) Ability to monitor the jute.maxBuffer usage in real-time
Date Mon, 06 Nov 2017 16:23:00 GMT
Andor Molnar created ZOOKEEPER-2933:

             Summary: Ability to monitor the jute.maxBuffer usage in real-time
                 Key: ZOOKEEPER-2933
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2933
             Project: ZooKeeper
          Issue Type: New Feature
          Components: jute, server
            Reporter: Andor Molnar
            Assignee: Andor Molnar
             Fix For: 3.5.4, 3.6.0

This is related to jute.maxbuffer problems on the server side when Leader generates a proposal
that doesn't fit into Follower's Jute buffer causing the quorum to be broken.

Proposed solution is to add the following new JMX Beans:

1. Add getJuteMaxBuffer to ZookeeperServerBean which monitors the current jute.maxbuffer setting,
2. Add get last/min/max ProposalSize to LeaderBean which monitors the size of the latest/min/max
