> Currently, only some James metrics are available for ActiveMQ which are exposed in WebAdmin. Namely, enqueuedMail and dequeuedMail for each registered queue (i.e. spool and outgoing). Some ActiveMQ broker stats (memoryUsage, memoryLimit, storeUsage, storeLimit, maxEnqueueTime, etc.) are currently not available.
> According to [https://activemq.apache.org/statisticsplugin.html] ActiveMQ Metrics can be obtained through subscription or by polling regularly. At the moment the statistics plugin is only used to get the size of a queue.
> I propose to poll ActiveMQ statistics via ActiveMQHealthCheck and publish those as metrics. Currently, the health check creates a session and checks if no exception occurred.
> What do you think?
