AWS OpenTelemetry X-Ray IdGenerator

[![NPM Published Version][npm-img]][npm-url] [![Apache License][license-image]][license-image]

The OpenTelemetry IdGenerator for AWS X-Ray generates trace IDs with its first four bytes set to the start time of the trace followed by a unique identifier consisting of 12 bytes of randomly generated numbers. OpenTelemetry offers an extension point which allows the usage of this custom IdGenerator as opposed to the out-of-the-box random IdGenerator, enabling compatibility with AWS X-Ray.

Status

| Maturity | Component Owner | Compatibility | | -------------------------------------- | ----------------------------------------------------- | --------------------- | | Stable | @carolabadeer | API 1.0+SDK 1.0+ |

Installation

npm install --save @opentelemetry/id-generator-aws-xray

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { AWSXRayIdGenerator } = require('@opentelemetry/id-generator-aws-xray');

const tracerConfig = {
  idGenerator: new AWSXRayIdGenerator(),
  resources: resources
};
const tracerProvider = new NodeTracerProvider(tracerConfig);

Trace ID Details

Example trace ID format: 58406520a006649127e371903a2de979

A trace ID consists of two parts:

1. Timestamp: The first 8 hexadecimal digits represent the time of the original request in Unix epoch time. For example, 10:00 AM December 1st, 2016 PST in epoch time is 1480615200 seconds, or 58406520 in hexadecimal digits.
2. Unique Identifier: The last 24 hexadecimal digits is an random identifier for the trace.
