## 📋 What the Scheduler Does

Every day at 8:00 AM, the scheduler will:

1. **Process Late Payments**
   - Calculate late fees for overdue billings
   - Apply late payment charges based on company settings
   - Mark billings as overdue

2. **Create Disconnection Notices**
   - Identify billings eligible for disconnection
   - Create disconnection notice records
   - Update disconnection status to 'notice_sent'

3. **Log Results**
   - Total companies processed
   - Late fees added
   - Disconnection notices created
   - Any errors encountered

## 🔧 Cron Job Setup (Linux/Unix)

### **Option 1: Add to crontab (Recommended)**

#### **Step 1: Edit crontab**
```bash
sudo crontab -e
```

#### **Step 2: Add this line to the crontab**
```cron
* * * * * cd /var/www/html/billing.happyimart.com && php artisan schedule:run >> /var/log/laravel-scheduler.log 2>&1
```

**Explanation**:
- `* * * * *` = Run every minute (Laravel's scheduler checks every minute)
- `cd /var/www/html/billing.happyimart.com` = Navigate to project directory
- `php artisan schedule:run` = Execute scheduled tasks
- `>> /var/log/laravel-scheduler.log 2>&1` = Log all output

#### **Step 3: Verify crontab entry**
```bash
sudo crontab -l | grep schedule:run
```

**Expected output**:
```
* * * * * cd /var/www/html/billing.happyimart.com && php artisan schedule:run >> /var/log/laravel-scheduler.log 2>&1
```

---

### **Option 2: Use Supervisor (Advanced)**

If using Supervisor for background processes:

#### **Step 1: Create config file**
```bash
sudo nano /etc/supervisor/conf.d/laravel-scheduler.conf
```

#### **Step 2: Add configuration**
```ini
[program:laravel-scheduler]
process_name=%(program_name)s
command=php /var/www/html/billing.happyimart.com/artisan schedule:work
autostart=true
autorestart=true
redirect_stderr=true
stdout_logfile=/var/log/supervisor/laravel-scheduler.log
user=www-data
```

#### **Step 3: Update and start supervisor**
```bash
sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start laravel-scheduler
```

---

### **Option 3: Use schedule:work (Development/Testing)**

For testing or small deployments:

```bash
# Run in background
php artisan schedule:work >> /var/log/laravel-scheduler.log 2>&1 &

# Or use nohup
nohup php artisan schedule:work >> /var/log/laravel-scheduler.log 2>&1 &
```

---

## ✅ Verification Steps

### **Step 1: Check schedule is registered**
```bash
cd /var/www/html/billing.happyimart.com
php artisan schedule:list
```

**Expected output**:
```
  0 8 * * *  php artisan payments:process-late .... Next Due: 6 hours from now
```

### **Step 2: Test the command manually**
```bash
php artisan payments:process-late -v
```

**Expected output**:
```
Starting late payment processing...
Processing late payments for all companies...

=== Processing Results ===
Companies Processed: X
Late Fees Added: X
Billings Marked Overdue: X
Disconnection Notices Created: X
Late payment processing completed successfully!
```

### **Step 3: Test schedule execution**
```bash
# Run the scheduler once
php artisan schedule:run -v
```

### **Step 4: Monitor logs**
```bash
# Watch logs in real-time
tail -f /var/log/laravel-scheduler.log

# Check for errors
grep -i error /var/log/laravel-scheduler.log
```

## 📊 Current Schedule Configuration

**File**: `routes/console.php`

```php
Schedule::command('payments:process-late')
    ->dailyAt('08:00')
    ->name('process-late-payments')
    ->withoutOverlapping()
    ->onOneServer();
```

### **Parameters Explained**:

| Parameter | Meaning |
|-----------|---------|
| `dailyAt('08:00')` | Runs every day at 8:00 AM |
| `name('process-late-payments')` | Unique name for identifying this task |
| `withoutOverlapping()` | Prevents concurrent runs (max 24 hours) |
| `onOneServer()` | Only runs on one server (multi-server safe) |

---

## 🔧 Adjusting the Schedule

### **Change Time of Day**
Edit `routes/console.php`:
```php
->dailyAt('22:00')  // Run at 10 PM instead
```

### **Run Every 6 Hours**
```php
->everyFourHours()
// OR
->everyMinutes(360)
```

### **Run Multiple Times Daily**
```php
->twiceDaily(8, 20)  // 8 AM and 8 PM
```

### **Remove One-Server Restriction** (if not multi-server)
```php
// Remove this line:
->onOneServer()
```

## 📋 Useful Commands

### **List all scheduled tasks**
```bash
php artisan schedule:list
```

### **Run scheduler once**
```bash
php artisan schedule:run
```

### **Test specific scheduled command**
```bash
php artisan schedule:test payments:process-late
```

### **Clear schedule cache**

php artisan schedule:clear-cache
```

### **Debug scheduled task**

## 🐛 Troubleshooting

### **Command Not Running**

**Check 1: Crontab is active**
```bash
ps aux | grep cron
# Should show cron daemon running
```

**Check 2: Crontab entry exists**
```bash
crontab -l | grep schedule:run
```

**Check 3: PHP path is correct**
```bash
which php
# Use full path if needed: /usr/bin/php or /usr/local/bin/php
```

**Check 4: Directory path is correct**
```bash
cd /var/www/html/billing.happyimart.com && ls artisan
# Should show artisan file
```

### **Logs Not Showing**

Check log directory permissions:
```bash
sudo touch /var/log/laravel-scheduler.log
sudo chmod 666 /var/log/laravel-scheduler.log
sudo chown www-data:www-data /var/log/laravel-scheduler.log
```

### **Permission Denied**

Make sure the web server user can run the command:
```bash
sudo chown -R www-data:www-data /var/www/html/billing.happyimart.com
sudo chmod -R 755 /var/www/html/billing.happyimart.com
```

### **Database Connection Issues**

Check `.env` file is readable:
```bash
sudo chmod 644 /var/www/html/billing.happyimart.com/.env
```

## 📊 Monitoring the Scheduler

### **Check if scheduler ran today**
```bash
grep "$(date +%Y-%m-%d)" /var/log/laravel-scheduler.log
```

### **Count successful runs**
```bash
grep "Late payment processing completed successfully" /var/log/laravel-scheduler.log | wc -l
```

### **Check for errors**
```bash
grep -i "error\|failed" /var/log/laravel-scheduler.log
```

### **Monitor in real-time** (while scheduler runs)
```bash
tail -f /var/log/laravel-scheduler.log
```

---

## 🚀 After Setup

### **1. Monitor Dashboard**
- Go to Company Dashboard
- Check **Overdue Billings** section
- Check **Disconnection Eligible** section
- Verify **Recent Late Fees** are being applied

### **2. Verify Payments Table**
```bash
php artisan tinker
>>> App\Models\Payment::where('payment_type', 'late_fee')->latest()->take(5)->get();
```

### **3. Check Activity Logs**
- Navigate to Activity Logs in dashboard
- Look for payment processing activities
- Verify times match scheduled time (8 AM)

---

## 📈 Performance Considerations

### **Processing Time**
- Small companies (< 100 billings): ~1-2 seconds
- Medium companies (100-1000 billings): ~5-10 seconds
- Large companies (1000+ billings): ~10-30 seconds

### **Database Impact**
- Low disk I/O (read-heavy)
- Minimal CPU usage
- No locks on client operations

### **Scaling with Multiple Companies**
- Process one company at a time
- Total time = sum of all company times
- Example: 5 companies with 500 billings each ≈ 30 seconds
