November 9, 2022
Node.js agent v9.6.0

Notes

  • Dropped support for vision, and instead only instrument @hapi/vision.

  • Updated configuration system to automatically create an environment variable mapping for a new config value.

    • It will follow a convention of NEW_RELIC_PATH_TO_CONFIG_KEY.
    • For example if there is a new configuration option of config.nested.object_path.enabled the env var would be NEW_RELIC_NESTED_OBJECT_PATH.ENABLED.
  • Removed transaction_tracer.hide_internals configuration. All of the internal configuration is now handled by Javascript symbols instead of non-enumerable properties, so there is no longer a performance penalty, as symbols are already hidden by default.

October 24, 2022
Node.js agent v9.4.0

Notes

  • Removed legacy agent async context propagation. The default behavior is now what was behind the feature_flag.new_promise_tracking. You can read more about the difference here.

  • Fixed an issue with the ES Module loader that properly registers instrumentation when the file path included url encoded characters.

  • Added an API for enqueuing application logs for forwarding

    newrelic.recordLogEvent({ message: 'hello world', level: 'info' })`

    Note: If you're including a serialized error make sure it's on the error key of the log event:

    const error = new Error('testing errors');
    newrelic.recordLogEvent({ message: 'error example', level: 'error', error })
  • Fixed cassandra-driver instrumentation to properly set instance details on query segments/spans.

  • Added a new context manager that leverages AsyncLocalStorage for async context propagation.

    • This will be available via a feature flag config.feature_flag.async_local_context
    • Alternatively you can set the environment variable of NEW_RELIC_FEATURE_FLAG_ASYNC_LOCAL_CONTEXT=1
    • By enabling this feature flag it should make the agent use less memory and CPU.

Support statement:

  • New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.

October 17, 2022
Node.js agent v9.3.0

Notes

  • Added instrumentation to bunyan to support application logging use cases: forwarding, local decorating, and metrics.

    Big thanks to @brianphillips for his contribution

  • Added c8 to track code coverage.

  • Added documentation about custom instrumentation in ES module applications

Support statement:

  • New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.

October 6, 2022
Node.js agent v9.2.0

Notes

  • Added ability to instrument ES Modules with the New Relic ESM Loader.

  • Added support for custom ESM instrumentation.

    • There is structure to registering custom ESM instrumentation. Set the relative path to the instrumentation entry point via api.esm.custom_instrumentation_entrypoint
    • Sample custom ESM instrumentation entrypoint
    • All the newrelic.instrument* methods will still work except newrelic.instrumentLoadedModule. This is because it is geared toward CommonJS modules.
  • Added test for asserting ESM loader functionality on ESM-only package

  • Added supportability metric of Supportability/Nodejs/Collector/MaxPayloadSizeLimit/<endpoint> when max_payload_size_in_bytes configuration value is exceeded.

  • Removed application_logging.forwarding.enabled stanza from sample config as the feature is now enabled by default.

Support statement:

  • New Relic recommends that you upgrade the agent regularly to ensure that you're getting the latest features and performance benefits. Additionally, older releases will no longer be supported when they reach end-of-life.
