+### Discover all events fired in one request
+
+If you want to implement a new listener to a specific event but you don't know its name, you can log all events fired during the request.
+
+You can use the `\Illuminate\Support\Facades\Event::listen()` method on `boot()` method of `app/Providers/EventServiceProvider.php` to catch all events fired.
+
+**Important:** If you use the `Log` facade within this event listener then you will need to exclude events named `Illuminate\Log\Events\MessageLogged` to avoid an infinite loop. 
+(Example: `if ($event == 'Illuminate\\Log\\Events\\MessageLogged') return;`)
+
+```php
+// Include Event...
+use Illuminate\Support\Facades\Event;
+
+// In your EventServiceProvider class...
+public function boot()
+{
+    parent::boot();
+
+    Event::listen('*', function ($event, array $data) {
+        // Log the event class
+        error_log($event);
+
+        // Log the event data delegated to listener parameters
+        error_log(json_encode($data, JSON_PRETTY_PRINT));
+    });
+}
+```
