+#### Naming Single Server Jobs
+
+Sometimes you may need to schedule the same job to be dispatched with different parameters, while still instructing Laravel to run each permutation of the job on a single server. To accomplish this, you may assign each schedule definition a unique name via the `name` method:
+
+```php
+$schedule->job(new CheckUptime('https://laravel.com'))
+            ->name('check_uptime:laravel.com')
+            ->everyFiveMinutes()
+            ->onOneServer();
+
+$schedule->job(new CheckUptime('https://vapor.laravel.com'))
+            ->name('check_uptime:vapor.laravel.com')
+            ->everyFiveMinutes()
+            ->onOneServer();
+```
