OpenTelemetry Tracing for Magento 2

Overview

OpenTelemetry Tracing is a Magento 2 module that integrates seamlessly with Magento's built-in Profiling functionality to provide advanced tracing capabilities. By adding a custom tracing driver, this module enables detailed performance monitoring and analysis, helping developers optimize their Magento applications effectively and for free.

Features

  • Enhanced Profiling: Extends Magento's native profiler with advanced tracing capabilities.
  • Jaeger Compatibility: Integrates with Jaeger for distributed tracing using the jonahgeorge/jaeger-client-php library.
  • Grafana Tempo Support: Compatible with Grafana Tempo through the OpenTelemetry endpoint, allowing for comprehensive monitoring and visualization.
  • Flexible Configuration: Easily configure tracing settings via JSON files or Magento CLI commands.

Compatibility

Jaeger

OpenTelemetry Tracing integrates with Jaeger, a popular open-source distributed tracing system. This integration is powered by the jonahgeorge/jaeger-client-php library, ensuring reliable and efficient tracing capabilities.

Grafana Tempo

The module also supports Grafana Tempo, enabling users to leverage Grafana's powerful visualization tools through the OpenTelemetry endpoint. This compatibility allows for seamless tracing data collection and analysis within the Grafana ecosystem.

Installation

  1. Clone the Repository:
composer require poespas/opentelemetry-tracing-magento2
  1. Enable the Module:
bin/magento module:enable Poespas_OpentelemetryTracing
bin/magento setup:upgrade

Configuration

You can configure the tracing driver using a JSON configuration file or via the Magento CLI command.

Using var/profiler.flag File

Create or update the var/profiler.flag file in the root of the magento installation with your JSON configuration:

{
  "drivers": [
    {
      "type": "\\Poespas\\OpentelemetryTracing\\Profiler\\Driver\\TracingDriver",
      "application_name": "my-magento-app",
      "config": {
        "local_agent": {
          "reporting_host": "127.0.0.1",
          "reporting_port": 14268
        },
        "dispatch_mode": "jaeger_over_binary_http"
      }
    }
  ]
}

Using Magento CLI Command

Alternatively, enable the profiler with a minified JSON configuration using the following command:

bin/magento dev:profiler:enable '{"drivers":[{"type":"\\Poespas\\OpentelemetryTracing\\Profiler\\Driver\\TracingDriver","application_name":"my-magento-app","config":{"local_agent":{"reporting_host":"127.0.0.1","reporting_port":14268},"dispatch_mode":"jaeger_over_binary_http"}}]}'
