Scout Lumen APM Agent

Monitor the performance of PHP Lumen applications with Scout's PHP APM Agent. Detailed performance metrics and transaction traces are collected once the scout-apm package is installed and configured.

Requirements

• PHP Version: PHP 7.2+ (PHP 8.3+ is recommended)
• Lumen Version: 5.5+

Quick Start

A Scout account is required. Signup for Scout.

composer require scoutapp/scout-apm-lumen

Add the ScoutApmServiceProvider to your bootstrap/app.php, for example:

// $app->register(App\Providers\AppServiceProvider::class);
// $app->register(App\Providers\AuthServiceProvider::class);
// $app->register(App\Providers\EventServiceProvider::class);
$app->register(\Scoutapm\Laravel\Providers\ScoutApmServiceProvider::class);

Add the four middleware to your bootstrap/app.php, for example:

$app->middleware([
    // These three should be as early as possible in the pipeline:
    \Scoutapm\Laravel\Middleware\SendRequestToScout::class,
    \Scoutapm\Laravel\Middleware\IgnoredEndpoints::class,
    \Scoutapm\Laravel\Middleware\MiddlewareInstrument::class,
    
    // The rest of your middleware should go here
    // ...
    
    // This middleware should come last
    \Scoutapm\Laravel\Middleware\ActionInstrument::class,
]);

If you wish to use the \Scoutapm\Laravel\Facades\ScoutApm facade, you should also enable facades if you did not already by uncommenting the withFacades() call in bootstrap/app.php:

$app->withFacades();

Configuration

In your .env file, make sure you set a few configuration variables:

SCOUT_KEY=ABC0ZABCDEFGHIJKLMNOP
SCOUT_NAME="My Lumen App"
SCOUT_MONITOR=true

Your key can be found in the Scout organization settings page.

Logging Verbosity

Once you have set up Scout and are happy everything is working, you can reduce the verbosity of the library's logging system. The library is intentionally very noisy by default, which gives us more information to support our customers if something is broken. However, if everything is working as expected, these logs can be reduced by setting the log_level configuration key to a higher Psr\Log\LogLevel. For example, if you are using .env configuration:

SCOUT_LOG_LEVEL=error

Any of the constants defined in \Psr\Log\LogLevel are acceptable values for this configuration option.
