@opentelemetry/instrumentation-pino

OpenTelemetry instrumentation for pino

This module provides automatic instrumentation for injection of trace context to pino.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @opentelemetry/instrumentation-pino

Usage

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { PinoInstrumentation } = require('@opentelemetry/instrumentation-pino');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();
provider.register();

registerInstrumentations({
  instrumentations: [
    new PinoInstrumentation({
      // Optional hook to insert additional context to log object.
      logHook: (span, record, level) => {
        record['resource.service.name'] = provider.resource.attributes['service.name'];
      },
    }),
    // other instrumentations
  ],
});

const pino = require('pino');
const logger = pino();
logger.info('foobar');
// {"msg":"foobar","trace_id":"fc30029f30df383a4090d3189fe0ffdf","span_id":"625fa861d19d1056","trace_flags":"01", ...}

Fields added to pino log objects

For the current active span, the following fields are injected:

• trace_id
• span_id
• trace_flags

When no span context is active or the span context is invalid, injection is skipped.

Supported versions
