@opentelemetry/tracing
Advanced tools
The tracing module contains the foundation for all tracing SDKs of opentelemetry-js.
Used standalone, this module provides methods for manual instrumentation of code, offering full control over span creation for client-side JavaScript (browser) and Node.js.
It does not provide automated instrumentation of known libraries, context propagation for asynchronous invocations or distributed-context out-of-the-box.
For automated instrumentation for Node.js, please see @opentelemetry/node.
npm install --save @opentelemetry/api
npm install --save @opentelemetry/tracing
const opentelemetry = require('@opentelemetry/api');
const { BasicTracerProvider } = require('@opentelemetry/tracing');
// To start a trace, you first need to initialize the Tracer provider.
// NOTE: The default OpenTelemetry tracer provider does not record any tracing information.
// Registering a working tracer provider allows the API methods to record traces.
new BasicTracerProvider().register();
// To create a span in a trace, we used the global singleton tracer to start a new span.
const span = opentelemetry.trace.getTracer('default').startSpan('foo');
// Set a span attribute
span.setAttribute('key', 'value');
// We must end the spans so they become available for exporting.
span.end();
Tracing configuration is a merge of user supplied configuration with both the default
configuration as specified in config.ts and an
environmentally configurable sampling (via OTEL_TRACES_SAMPLER and OTEL_TRACES_SAMPLER_ARG).
See examples/basic-tracer-node for an end-to-end example, including exporting created spans.
