OpenTelemetry Propagator Jaeger

OpenTelemetry Jaeger propagator provides HTTP header propagation for systems that are using Jaeger HTTP header format.

Format: {trace-id}:{span-id}:{parent-span-id}:{flags}

• {trace-id}

  • 64-bit or 128-bit random number in base16 format.
  • Can be variable length, shorter values are 0-padded on the left.
  • Value of 0 is invalid.

• {span-id}

  • 64-bit random number in base16 format.

• {parent-span-id}

  • Set to 0 because this field is deprecated.

• {flags}

  • One byte bitmap, as two hex digits.

Example of usage:

const { NodeTracerProvider } = require('@opentelemetry/node');
const { JaegerHttpTracePropagator } = require('@opentelemetry/propagator-jaeger');

const provider = new NodeTracerProvider();
provider.register({
  // Use Jaeger propagator
  propagator: new JaegerHttpTracePropagator()
});
