If the Artemis team finds this feature useful for the project, please let me
know as I have already a draft available.
> Peek oldest message in a queue with JMX QueueControl
> ----------------------------------------------------
>
> Key: ARTEMIS-5077
> URL: https://issues.apache.org/jira/browse/ARTEMIS-5077
> Project: ActiveMQ Artemis
> Issue Type: New Feature
> Components: JMX, management
> Reporter: Jean-Pascal Briquet
> Priority: Minor
>
> This feature proposal aims to provide a JMX method that allows operators to
> find the oldest message in a queue when needed.
> Messages in a queue can be unordered in the following scenarios (non
> exhaustive list):
> - message redistribution in the cluster
> - message move from one queue to another
> The existing peekFirstMessage method returns the message at top of the queue
> but in the above scenarios it is not necessarily always the oldest message.
> *Proposal:*
> - Method "peekOldestMessageAsJSON(filter)".
> The filter allows messages in the queue to be filtered before searching for
> the oldest message. This parameter is optional.
> The oldest message can be found by browsing the queue aand comparing each
> message's timestamp with the current oldest message candidate.
> The method output would list message properties, it is equivalent to the
> output of the existing peekFirstMessageAsJSON method.
> The proposed method would be potentially heavy, as it needs to scan all
> messages in a queue.
> Therefore, the method description should clearly highlight it.
