README

This package provides auto-instrumentation for PHP's native session functions.

Installation

composer require open-telemetry/opentelemetry-auto-session

Usage

The instrumentation hooks into PHP's native session functions to provide tracing capabilities. It automatically creates spans for session operations like session_start() and session_destroy().

<?php
// Make sure to initialize the OpenTelemetry SDK before using sessions
// ...

// Register the PHP Session instrumentation
\OpenTelemetry\Contrib\Instrumentation\PhpSession\PhpSessionInstrumentation::register();

// Now any session operations will be automatically traced
session_start();
// ... your code ...
session_destroy();
