New Relic Java Agent - Transaction Listener Service

This lightweight Java Agent extension listens for Java Agent configChanged and transactionFinished events.

It adds the labels from the Agent's configuration yml file to each completed Agent transaction subject to the Rules below. The labels are read on startup and on configChanged events.

The added labels appear in every Transaction Trace as user attributes.

Rules

1. envvars always ovverride the configuration file
2. envvars are always uppercase
3. Always look for deployment_version label
4. If transaction_listener_service_labels is present in the common section of newrelic.yml as a semi-colon delimited list of labels then use it to filter which labels to use
5. If transaction_listener_service_labels is not present in the common section of newrelic.yml then report all labels

1. Download the latest release jar files.
2. In the New Relic Java directory (the one containing newrelic.jar), create a directory named extensions if it does not already exist.
