isdown Command

[szepeviktor]

When Laravel is down it would be nice to figure out its current state.

Could you add an isdown command?

        $downFile = storage_path('framework/down');
        if (!file_exists($downFile)) {
            $this->info('Application is up.');
            return;
        }

        $data = json_decode(file_get_contents($downFile), true);

        $status = sprintf("Time: %s\nRetry: %d\nMessage: '%s'",
            date('c', $data['time']),
            $data['retry'] ?: 0,
            $data['message']
        );
        $this->line($status);

What's the use case for this?

You can visit the app in the browser and see pretty clearly that the app is down. If you're using a monitoring service, it should be able to detect the 503 being returned when the application is in maintenance mode.

Thank you.

I am a stay-at-the-terminal type.

And in script it is necessary to check for maintenance mode.

You can check $this->app->isDownForMaintenance() in your commands.

Thanks.

It's $this->laravel, not $this->app.

In a script, you could also simply check if storage/framework/down exists. If that file exists, the application is currently down.

Thank you. That is OK.
