Monitor ActiveMQ Message Broker

Overview​

Activemq sfAgent plugin provides metrics related to message traffic distribution and other internal transactions among the brokers.

Metrics collected by the plugin are organized across the following categories

  • Broker stats: contain transactional data and metrics related to broker state
  • Topic stats: provide metrics for analyzing internal transactions associated with each topic
  • Queue stats: provide metrics for analyzing internal transactions associated with each queue
  • JVM stats: contain all JVM related metrics like garbage collection details, memory pools, loaded/unloaded classes etc.

Activemq logger plugin collects general logs comprising state change and broker specific information generated by the activemq message broker.
