Robbie Gemmell updated QPID-2178:
---------------------------------
Status: Ready To Review (was: In Progress)
> Allow viewing of channel flow control status via JMX Management Console
> -----------------------------------------------------------------------
>
> Key: QPID-2178
> URL: https://issues.apache.org/jira/browse/QPID-2178
> Project: Qpid
> Issue Type: New Feature
> Components: Java Management : JMX Console, Java Management : JMX
> Interface
> Reporter: Robbie Gemmell
> Assignee: Robbie Gemmell
> Fix For: 0.6

>
> When Flow Control is being utilised on the broker, it may be useful to expose
> the status of a channel (based on thevalue of _blocking in AMQChannel) as a
> read-only property via the management console.
> Channel properties are currently only exposed by the broker over JMX via the
> ManagedConnection mbean interface which defines a channels() method
> implemented in the AMQProtocolSessionMBean, that returns a data set
> consisting of channel id, transactional status, default queue, and number of
> unacked messages for all channels on the connection. In order to expose the
> flow controlled status of the channel, this result set would be expanded to
> include the value of the new _blocking AtomicBoolean within AMQSession.
> Expanding the result set would not affect compatability with the older
> console UI, which should automatically display it thanks to its completely
> generic construction. The new console UI utilises this particular information
> set quite differently in order to construct a structured table and would not
> make use of the additional information until modified to do so (its presence
> would not interfere until that time, it simply wont be utilised) by
> performing a small update to add a new table column when the additional
> information is available on supporting brokers.
