How do I get started with Correlation IDs?

Getting started with Correlation IDs is essential for tracking and managing requests across distributed systems. A Correlation ID is a unique identifier that you generate for each request. This ID helps in tracing requests through various services, making it easier to debug and monitor systems.

Here’s a simple example of how to implement a Correlation ID in PHP:

<?php // Generate a unique correlation ID function generateCorrelationId() { return uniqid('corr-', true); } // Set the correlation ID for the request $correlationId = generateCorrelationId(); header("X-Correlation-ID: $correlationId"); // Log the correlation ID error_log("Request received with Correlation ID: $correlationId"); ?>
