# Domain Expiration Monitoring Setup

This feature allows you to monitor domain expiration dates and receive alerts when domains are expiring soon.

## Features Implemented

### 1. Database Migration
- **Table:** `domains`
- **Columns:**
  - `id` - Primary key
  - `site_id` - Foreign key to sites table
  - `domain` - Domain name (e.g., example.com)
  - `expires_at` - Domain expiration date
  - `last_checked_at` - Last WHOIS check timestamp
  - `is_active` - Enable/disable monitoring
  - `created_at`, `updated_at` - Timestamps

### 2. Models & Relationships
- **Domain Model** (`app/Models/Domain.php`)
  - Belongs to Site
  - Helper methods:
    - `isExpiringSoon()` - Check if expiring within 30 days
    - `isExpired()` - Check if already expired
    - `daysUntilExpiration()` - Get days remaining

- **Site Model** updated with `domains()` relationship

### 3. Background Job
- **Job:** `CheckDomainExpiry` (`app/Jobs/CheckDomainExpiry.php`)
  - Performs WHOIS lookup via API
  - Updates domain expiration date
  - Creates notifications for expiring domains (within 30 days)
  - Logs errors for monitoring

### 4. Artisan Command
- **Command:** `monitor:domains`
  - Dispatches `CheckDomainExpiry` job for all active domains
  - Shows progress bar
  - Run manually: `php artisan monitor:domains`

### 5. Scheduled Task
- **Schedule:** Daily at midnight (configurable in `routes/console.php`)
- Automatically runs `monitor:domains` command
- Logs output to `storage/logs/domain-monitoring.log`

### 6. Web Interface

#### Routes
- `GET /domains` - List all domains
- `GET /domains/create` - Add new domain form
- `POST /domains` - Store new domain
- `GET /domains/{domain}` - View domain details
- `GET /domains/{domain}/edit` - Edit domain form
- `PUT /domains/{domain}` - Update domain
- `DELETE /domains/{domain}` - Delete domain
- `POST /domains/{domain}/check` - Manually trigger WHOIS check

#### Views
- `resources/views/domains/index.blade.php` - Domain list with status badges
- `resources/views/domains/create.blade.php` - Add new domain
- `resources/views/domains/edit.blade.php` - Edit domain
- `resources/views/domains/show.blade.php` - Domain details and expiration info

## Setup Instructions

### 1. Configure WHOIS API

The system uses **WHOIS XML API** (https://www.whoisxmlapi.com/) by default. You can use alternatives like:
- WhoisFreaks (https://whoisfreaks.com/)
- Domainr (https://domainr.com/)

**Add to `.env` file:**
```env
WHOIS_API_KEY=your_api_key_here
```

**Get a free API key:**
1. Visit https://www.whoisxmlapi.com/
2. Sign up for a free account
3. Get your API key from the dashboard
4. Free tier includes 500 requests/month

### 2. Run the Migration

If not already run:
```bash
./vendor/bin/sail artisan migrate
```

### 3. Start the Queue Worker

The domain checking jobs run in the background queue:
```bash
./vendor/bin/sail artisan queue:work
```

Or if you're already running the queue worker, it will automatically pick up these jobs.

### 4. Set Up Scheduled Tasks

Make sure your Laravel scheduler is running. In production, add this to your crontab:
```
* * * * * cd /path-to-your-project && php artisan schedule:run >> /dev/null 2>&1
```

In development with Sail, the scheduler should run automatically if you started with `composer dev`.

### 5. Test the System

1. **Add a domain:**
   - Navigate to `/domains`
   - Click "Add Domain"
   - Select a site and enter a domain name
   - Save

2. **Manual check:**
   - View the domain details
   - Click "Check Expiry Now"
   - The job will queue and process in the background

3. **Test the command:**
   ```bash
   ./vendor/bin/sail artisan monitor:domains
   ```

## Usage

### Adding Domains
1. Go to "Domain Monitoring" in your application
2. Click "Add Domain"
3. Select the associated site
4. Enter the domain name (without http://)
5. Save - the system will automatically check expiration

### Monitoring
- **Automatic:** Runs daily via scheduled task
- **Manual:** Click "Check Now" on any domain
- **Command:** Run `php artisan monitor:domains` anytime

### Notifications
When a domain is expiring within 30 days or has expired:
- A notification is created in the system
- Shows in your alerts/notifications section
- Contains domain name, expiration date, and days remaining

### Status Badges
- **Active** (Green) - Domain valid, not expiring soon
- **Expiring Soon** (Yellow) - Expires within 30 days
- **Expired** (Red) - Domain has expired
- **Unknown** (Gray) - Not yet checked

## Alternative WHOIS APIs

If you want to use a different WHOIS provider, modify `app/Jobs/CheckDomainExpiry.php`:

### WhoisFreaks Example:
```php
$response = Http::timeout(30)
    ->get('https://api.whoisfreaks.com/v1.0/whois', [
        'apiKey' => config('services.whois.api_key'),
        'whois' => $this->domain->domain,
    ]);

// Parse response differently based on provider's format
```

### Free WHOIS API:
You can also use a free WHOIS lookup service, but be aware of rate limits and reliability.

## Troubleshooting

### Jobs not processing
- Check queue worker is running: `ps aux | grep queue`
- Check failed jobs: `./vendor/bin/sail artisan queue:failed`
- Restart queue: `./vendor/bin/sail artisan queue:restart`

### WHOIS API errors
- Verify API key is set in `.env`
- Check API quota/limits
- Review logs: `storage/logs/laravel.log`

### Schedule not running
- Development: Ensure scheduler is part of your dev command
- Production: Verify cron job is set up
- Test manually: `./vendor/bin/sail artisan schedule:run`

## API Response Format

The job expects WHOIS API responses with expiry date in these formats:
- `WhoisRecord.registryData.expiresDate`
- `WhoisRecord.expiresDate`
- `expiresDate`

Dates can be in any format parseable by Carbon (ISO 8601, RFC 2822, etc.)

## Future Enhancements

Consider adding:
- Email notifications for expiring domains
- Slack/Discord webhooks
- Configurable warning thresholds (7, 14, 30, 60 days)
- Domain auto-renewal reminders
- Historical tracking of expiration checks
- Bulk import from CSV
- Integration with domain registrars
