To integrate AWS X-Ray, configure SensioLabsInsight in the service configuration file. By accessing the debugger URL in the application configuration file, you can view distributed tracing details, including request traces, function traces, and flame graphs, to help identify and optimize system performance.

How to use SensioLabsInsight to debug distributed tracing of PHP functions

Distributed tracing is important for understanding the interactions between various components within the application Interaction is invaluable. SensioLabsInsight is a powerful debugger that gives you insight into the execution of PHP functions.

Install SensioLabsInsight

First, install SensioLabsInsight in your project:

composer require sensiolabs/insight --dev

/**
 * @Traced()
 */
function calculate_total(array $prices)
{
    $total = 0;
    foreach ($prices as $price) {
        $total += $price;
    }
    return $total;
}

Debug distributed tracing

You can view distributed trace details by visiting http://localhost:8000/profiler/traces in your browser.

• Request tracing: Displays the call stack and duration of each request.
• Function tracing: Display the call stack, parameters and return value of the function.
• Flame graph: Provides a visual representation of function execution time.

With this information, you can quickly identify bottlenecks and optimize your code.
