About the Splunk Distribution of OpenTelemetry JS 🔗
The Splunk Distribution of OpenTelemetry JS is a wrapper for the OpenTelemetry Instrumentation for Node.js, an open source Node framework that automatically instruments Node applications and libraries so that they capture telemetry data at runtime.
You can automatically instrument any application written in Node.js 14 and higher. See Splunk OTel JS compatibility and requirements. To instrument applications that use Node versions lower than 14, use the SignalFx Tracing Library for Node.js.
Features of the Splunk Distribution of OpenTelemetry JS 🔗
In addition to the features of the OpenTelemetry Instrumentation for Node.js, like bundled exporters and propagators, the Splunk Distribution of OpenTelemetry JS provides additional custom features:
Sends trace and span data to Splunk Observability Cloud using the OTel Collector..
Collection of runtime metrics. See Metrics and attributes collected by the Splunk Distribution of OTel JS.
Instrumentation for HTTP server frameworks that returns server trace information in HTTP responses. See Server trace information.
Automatic injection of trace metadata into application logs. See Connect Node.js trace data with logs for Splunk Observability Cloud.
The Splunk Distribution of OpenTelemetry JS is supported by Splunk and is updated frequently, bringing bug fixes and new features to you before they are integrated in the upstream OTel repositories.
Defaults of the Splunk Distribution of OpenTelemetry JS 🔗
The Splunk Distribution of OpenTelemetry JS has the following default settings for context propagation, exporters, and trace settings:
W3C tracecontext and W3C baggage context propagation is activated by default. You can also configure B3 propagation. See Propagators configuration.
The OTLP exporter is configured by default to send spans to the local Splunk Distribution of OpenTelemetry Collector over gRPC.
