Java agent v3.45.0

Improvements

• RabbitMQ

The agent now provides instrumentation for RabbitMQ 5.0.

Note:

• This release changes instrumentation for all supported versions of RabbitMQ to use the exchange name instead of routing keys for the transaction name and produce/consume metrics. This should provide more meaningful transaction names, but will change what transactions you see in New Relic.

• Now reports queue purge

• No longer reports misleading MessageBroker consume metric for callbacks/message listeners

• Adds message properties to tracer attributes, and a configuration to disable them:

  message_tracer:
      segment_parameters:
        enabled: false

  Copy

Bug Fixes

• Exceptions thrown within scala Future/CallbackRunnable code could cause inaccurate transaction times
• Deadlock could occur when tracking asynchronous activity in Vert.x.
