Node.js agent release notesRSS

Reintroduced throttling during reading of instrumented application's dependency tree during startup, to prevent EMFILE issues.

Improved Restify support

• Added a new test stanza to run restify >=10 on Node 18.
• Update our versioned tests to support Restify 9.0.0.

Laid foundation for supporting Code Level Metrics via CodeStream. Note that this integration is not fully finished and should not be used.

Improved the readability and maintainability of agent by reducing the Cognitive Complexity of various aspects of the agent.

Added newrelic.noticeError() example to our API docs.

Upgraded @grpc/grpc-js from 1.6.9 to 1.7.3.

Upgraded @grpc/proto-loader from 0.6.13 to 0.7.3.

Removed async from benchmark tests, fixed failing benchmark suites, and removed deprecated suite.

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.

커스텀 대시보드의 기본 제한을 분당 1,000개의 이벤트에서 분당 3,000개의 이벤트로 늘렸습니다. 커스텀 대시보드가 제한되는 시나리오에서, 이 변경 사항을 통해 더 많은 커스텀 대시보드를 뉴렐릭으로 보낼 수 있습니다. 또한 분당 100,000개의 이벤트라는 구성 가능한 새로운 최대 제한이 있습니다. 제한을 변경하려면 custom_insights_events에 대한 문서를 참조하십시오. 변경 사항 및 커스텀 대시보드가 삭제되고 있는지 확인하는 방법에 대해 자세히 알아보려면 Explorers Hub 게시물을 참조하십시오.

코드 커버리지 통계 수집을 포함하도록 CI 프로세스를 업데이트했습니다.

현재 기능 플래그에 대한 [문서)(https://github.com/newrelic/node-newrelic/blob/main/documentation/feature-flags.md)를 추가했습니다.

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.

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

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

• Example ESM application

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.
