-----------------------------------
Summary: Add more broker-level attributes to improve JMX-based
monitoring
Key: ARTEMIS-417
URL: https://issues.apache.org/jira/browse/ARTEMIS-417
Project: ActiveMQ Artemis
Issue Type: New Feature
Reporter: Lionel Cons
Here are some broker level attributes, useful for monitoring purposes, exposed
by ActiveMQ 5.x and not (yet) by Artemis.
- uptime: Uptime and UptimeMillis
- total number of connections since start (to derive a rate):
TotalConnectionsCount
- total number of messages received (to derive a rate): TotalEnqueueCount
- total number of messages sent (to derive a rate): TotalDequeueCount
- number of messages currently in the broker: TotalMessageCount
- current number of subscriptions/consumers: TotalConsumerCount
- memory store usage: MemoryPercentUsage
- disk store usage: TempPercentUsage and StorePercentUsage
Some of these may be computed from other MBeans (one could sum all the
MessageCount from all the queues) but this does not scale. With heavily used
brokers (e.g. thousands of destinations or connections or subscriptions...), it
is not really feasible to frequently iterate through many thousands MBeans just
to get an aggregated total.
