Laravel Real-Time Controllers monitoring

Valerio Barbera

Have you ever desired to see your code running, instead of being able to just imagine it?

Hi, I’m Valerio software engineer from Italy and CTO at Inspector.

As product owner I learned on my skin how an application issue can be so hard to fix, creating a negative impact on the users experience, or block new potential customers during on-boarding.

To help you get faster in identifying which part of the application is in trouble, we have designed an easy and ready to use way to directly monitor your application controllers and methods.

Many of us continue to discover bugs and errors in the applications thanks to direct reports by users.

It’s too dangerous today, because when a user reports a problem it’s just too late. For a user that report a problem there are many others that simply stop using our application silently, moving to another product that fits their needs better.

Emerging software houses needs to hide bugs and bottlenecks from users eyes as much as possible to provide a better customer experience than the competitors.

A real-time monitoring tool help developers to address this problem, but many tools out there need a lot of resources and time to be installed and configured, making the life of developers more complicated.

Inspector is a composer package to add real-time monitoring in your Laravel application, it’s very easy to install and use, and it takes less than one minute to get started.

Install the composer package to monitor Laravel

Install our package by running the command below in your terminal:

composer require inspector-apm/inspector-laravel

Configure the API key

Get a fresh API key by signing up for Inspector (https://app.inspector.dev/register) and creating a new application, it takes just a few seconds.

You’ll see installation instructions directly in the app screen:

Put the API key into your environment file:

INSPECTOR_API_KEY=13c37c434XXXXXXXXXXXX

Http Requests Monitoring

To activate inspection when your application is executed by an incoming http request you can use the WebRequestMonitoring middleware.

Thanks to the middleware you are free to decide on which routes you want activate execution tracing, based on your routes configuration or on your personal monitoring preferences. WebRequestMonitoring middleware works like any other Laravel middleware you are familiar to.

Basically you can attach the middleware in the App\Http\Kernel class in one or more of your predefined middleware groups:

/**
 * The application’s route middleware groups.
 *
 * @var array
 */
protected $middlewareGroups = [
   'web' => [
      …,
      \Inspector\Laravel\Middleware\WebRequestMonitoring::class,
   ],   'api' => [
      …,
      \Inspector\Laravel\Middleware\WebRequestMonitoring::class,
   ]
]

Identify Controller/Method execution

If you prefer to have a clear visibility of what controller and method are executed based on any HTTP request, you can use the code below inside the boot method of one of your ServiceProvider. Maybe the best place could be EventsServiceProvider.

use Illuminate\Routing\Events\RouteMatched;

/**
 * Register any events for your application.
 *
 * @return void
 */
public function boot() 
{
   parent::boot();  /*
   * Changes the way inspector reports transactions in your dashboard.
   */
   Event::listen(RouteMatched::class, function(RouteMatched $event) {
      $name = $event->route->getActionName();
 
      if(inspector()->isRecording()) {
         inspector()->currentTransaction()->name = $name;
      } else {
          inspector()->startTransaction($name);
      }
   });
}

This will change the way Inspector reports transactions in your dashboard from GET /path/{id} to [email protected] .

Conclusion

Inspector is a simple yet powerful real-time monitoring tool, designed to easy understand how your application processes are performing and get alerted if something goeas wrong.
