How to use Laravel Telescope for monitoring and profiling SQL queries

Laravel Telescope is a powerful debugging and introspection tool for Laravel applications. It allows you to monitor various aspects of your application, including SQL queries. Here's a step-by-step guide on how to use Laravel Telescope to monitor and profile SQL queries:

Step 1: Install Laravel Telescope

You can install Laravel Telescope using Composer. Open your terminal and run the following command:

bash
composer require laravel/telescope

Then, run the Telescope installation command:

bash
php artisan telescope:install

Finally, run the migrations to create the necessary database tables:

bash
php artisan migrate

Step 2: Configure Your Environment

By default, Telescope is only enabled in the local environment. You can customize this in the TelescopeServiceProvider class. Open App\Providers\TelescopeServiceProvider.php and modify the register method:

php
public function register()
{
    Telescope::ignoreMigrations();

    Telescope::filter(function (IncomingEntry $entry) {
        // Additional filters if needed
        return true;
    });
}

Step 3: Accessing Telescope Dashboard

You can access the Telescope dashboard by visiting /telescope in your web browser. If you're running your Laravel application locally, the URL would be something like http://localhost:8000/telescope.

Step 4: Monitoring SQL Queries

Telescope automatically records SQL queries and displays them in the dashboard. You can find them under the "Queries" tab. It provides details like the query, the time it took to execute, and any bindings used.

Example:

Let's say you have a controller method that fetches users from the database. Here's an example:

php
use App\Models\User;

public function index()
{
    $users = User::all();

    return view('users.index', compact('users'));
}

When you access this route, Laravel Telescope will record the SQL queries involved in fetching the users, and you can view them in the Telescope dashboard.

Remember to remove Telescope from your production environment, as it's intended for development and debugging purposes.

I hope this helps you get started with Laravel Telescope for monitoring and profiling SQL queries!

=== Happy Coding :)
