> 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
> Labels: buffer, buffer-length
> 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 proposal.
