Install the Laravel Nightwatch package via Composer:

composer require laravel/nightwatch

Step 3: Configure Your Application

After installation, publish the configuration file:

php artisan vendor:publish --provider="Laravel\Nightwatch\NightwatchServiceProvider"

Then, add your Nightwatch API key to your .env file:

NIGHTWATCH_API_KEY=your-api-key-here

Step 4: Start Monitoring

Once configured, Laravel Nightwatch will automatically begin monitoring your application. You can view your dashboard at:

https://nightwatch.laravel.com/dashboard

Dashboard Overview

The Laravel Nightwatch dashboard provides a comprehensive overview of your application's health and performance. Here's what you can expect to see:

Performance Metrics

Monitor key performance indicators such as:

Response Times: Track how quickly your application responds to requests
Database Query Performance: Identify slow queries that might be affecting performance
Memory Usage: Monitor your application's memory consumption
CPU Utilization: Keep an eye on server resource usage

Error Tracking

Laravel Nightwatch provides detailed error tracking capabilities:

// Example of an error captured by Nightwatch
{
  "type": "Exception",
  "message": "Undefined property: App\Models\User::$profile",
  "file": "/app/Http/Controllers/UserController.php",
  "line": 42,
  "trace": [...],
  "context": {
    "user_id": 123,
    "request_path": "/users/profile",
    "request_method": "GET"
  }
}

Advanced Features

Let's explore some of the more advanced features of Laravel Nightwatch.

Custom Metrics

You can define custom metrics to track specific aspects of your application:

// In your application code
use Laravel\Nightwatch\Facades\Nightwatch;

// Track a custom metric
Nightwatch::recordMetric('orders_processed', 1);

// Track a custom metric with context
Nightwatch::recordMetric('payment_processed', 149.99, [
    'payment_method' => 'credit_card',
    'currency' => 'USD'
]);

Request Monitoring

Laravel Nightwatch automatically monitors all incoming HTTP requests to your application, providing valuable insights into your application's traffic patterns and performance:

// Example of request data captured by Nightwatch
{
  "method": "POST",
  "url": "/api/orders",
  "duration": 235, // milliseconds
  "status": 201,
  "controller": "App\Http\Controllers\OrderController@store",
  "middleware": ["auth:api", "throttle:60,1"],
  "headers": {...},
  "payload": {...},
  "database_queries": [...]
}

Integrating with CI/CD

Laravel Nightwatch can be integrated into your CI/CD pipeline to monitor your application during the deployment process.

Deployment Tracking

Track deployments to correlate performance changes with code updates:

// In your deployment script
use Laravel\Nightwatch\Facades\Nightwatch;

Nightwatch::trackDeployment([
    'commit' => 'abc123',
    'branch' => 'main',
    'environment' => 'production',
    'deployer' => 'GitHub Actions'
]);

CI/CD Pipeline Integration

Here's an example of how to integrate Nightwatch monitoring into your GitHub Actions workflow:

// .github/workflows/deploy.yml

name: Deploy and Monitor

on:
  push:
    branches: [ main ]

jobs:
  deploy:
    runs-on: ubuntu-latest
    
    steps:
    - uses: actions/checkout@v2
    
    - name: Setup PHP
      uses: shivammathur/setup-php@v2
      with:
        php-version: '8.0'
    
    - name: Install Dependencies
      run: composer install -q --no-ansi --no-interaction --no-scripts --no-progress --prefer-dist
    
    - name: Deploy Application
      run: ./deploy.sh
    
    - name: Notify Nightwatch of Deployment
      env:
        NIGHTWATCH_API_KEY: ${{ secrets.NIGHTWATCH_API_KEY }}
      run: php artisan nightwatch:deployment
