Jean-Baptiste Onofré resolved AMQ-9552.
---------------------------------------
Resolution: Not A Problem
This ticket is covered by [https://github.com/apache/activemq/blob/main/activemq-client/src/main/java/org/apache/activemq/management/MessageFlowStatsImpl.java#L21]
using the _enqueuedMessageBrokerInTime_ or _enqueuedMessageTimestamp_ value.
> StatisticsPlugin - add metric lastMessageTimestamp
> --------------------------------------------------
>
> Key: AMQ-9552
> URL: https://issues.apache.org/jira/browse/AMQ-9552
> Project: ActiveMQ Classic
> Issue Type: Improvement
> Components: Broker
> Reporter: Grzegorz Kochański
> Assignee: Jean-Baptiste Onofré
> Priority: Minor
> Time Spent: 2h
> Remaining Estimate: 0h
>
> Metric {{lastMessageTimestamp}} can be captured from the modification time of metric {{enqueues:}}
>
> {code:java}
> statsMessage.setLong("lastMessageTimestamp", stats.getEnqueues().getLastSampleTime()); {code}
>
> Disclaimer: disadvantage of such approach is that after broker restart this value is holding start time of the broker (which may be relevant when the frequency of broker restarts is comparable to the frequency of enqueued messages)
