Arthur Naseef updated AMQ-3876:
-------------------------------
Attachment: WireTap.java
Attached WireTap.java which is a protoype client for requesting and recording
tapped messages.
> WireTap of TransportConnector messages for diagnostic purposes
> --------------------------------------------------------------
>
> Key: AMQ-3876
> URL: https://issues.apache.org/jira/browse/AMQ-3876
> Project: ActiveMQ
> Issue Type: New Feature
> Reporter: Arthur Naseef
> Priority: Minor
> Attachments: WireTap.java, WiretapPrototype1.patch
>
>
> Being able to tap into the flow of messages on a TransportConnection would
> greatly help with diagnosing problems such as complaints from clients that
> they are not receiving messages.
> Think "tcpdump" for broker traffic.
> A rough, working prototype will be attached.
> The idea in the prototype is a new Connector on the BrokerService which does
> the following:
> * accepts connections from a wire-tap tool (application)
> * accepts a request to tap a specific TransportConnection
> * adds a tap to the TransportConnection (requires change to
> TransportConnection)
> * sends a copy of every command sent over the connection, via the {{oneway}}
> call, to the tap
> After posting the prototype, I'll post wish-list items.
> If someone with more knowledge and background working with connectors can
> pick this up, that would be great. Otherwise, I'll plan to implement it,
> looking for any advice. For example, one concern is that the tap should
> prefer to drop content rather than either (a) use large amounts of resources
> to buffer them, or (b) in any way impacting the normal flow on the
> TransportConnection.
