OpenTelemetry Tracer

Overview

OpenTelemetry Tracer provides a robust tracing utility built on OpenTelemetry, enabling seamless instrumentation of asynchronous operations in your application. It supports auto-instrumentation and custom tracer configuration to effectively monitor performance and troubleshoot issues.

Installation

Install the package from npm:

npm install @bluealba-public/opentelemetry-tracer

Usage

Initialize tracing in your application by importing and calling the initTracing function:

import { initTracing } from '@bluealba-public/opentelemetry-tracer';

const tracing = initTracing({
  enabled: true,
  url: process.env.TRACE_URL,
  serviceName: 'your-service-name'
});

// Wrap asynchronous operations with tracing
const tracedOperation = tracing.withTracing('operation-span', async () => {
  // ... your code ...
});

For Fastify Applications >5.x

For Fastify applications, use the provided Fastify plugin to automatically trace incoming requests and responses:

npm install @autotelic/fastify-opentelemetry

import fastify from 'fastify';
import fastifyOpenTelemetry from '@autotelic/fastify-opentelemetry';

const app = fastify();

app.register(fastifyOpenTelemetry);

// ... existing code ...

Configuration

Customize the tracer with the following options:

• enabled: Toggle tracing on or off.
• url: Specify the OTLP trace exporter endpoint.
