## 🔧 Advanced Features

### 1. Auto-Healing

**How It Works:**
When enabled, failed endpoints are automatically retried with different strategies:

**Strategy 1: Custom Headers**
```python
headers = {"User-Agent": "Mozilla/5.0"}
```

**Strategy 2: Extended Timeout**
```python
timeout = 30  # Instead of default 10
```

**Strategy 3: Follow Redirects**
```python
follow_redirects = True
```

**Enable:**
Toggle "🔧 Enable Auto-Heal" checkbox at top

### 2. Force Testing

**Definition:** Testing with multiple retry attempts and detailed diagnostics

**Process:**
1. Initial attempt with 8-second timeout
2. If failed, wait 1 second
3. Retry with same parameters
4. Record all attempts
5. Calculate success/failure

**Benefits:**
- Catches intermittent failures
- Tests under load
- Validates reliability
- Measures consistency

### 3. Real-Time Monitoring

**Status:** Coming in future update

**Planned Features:**
- Auto-refresh every 60 seconds
- Background health checks

## 🔍 Troubleshooting

### Issue 1: Dashboard Won't Start

**Symptoms:**
- Import errors
- Module not found

**Solutions:**
```bash
# Install dependencies
pip install -r requirements_gradio.txt

# Or use startup script
./start_gradio_dashboard.sh
```

### Issue 2: Can't Connect to Services

**Symptoms:**
- FastAPI shows "❌ OFFLINE"
- HF Engine shows "❌ OFFLINE"

**Solutions:**
```bash
# Check if services are running
curl http://localhost:7860/health
curl http://localhost:8000/api/health

# Start services if needed
python app.py  # Terminal 1
cd hf-data-engine && python main.py  # Terminal 2
```

### Issue 3: Force Test Shows All Offline

**Possible Causes:**
1. Network/firewall blocking requests
2. Rate limiting from providers
3. Services not started
4. Datacenter IP blocking (for external APIs)

**Solutions:**
1. Verify services are running
2. Enable auto-heal for retry attempts
3. Test individual endpoints first
4. Check network connectivity
5. Try with VPN if IP is blocked

### Issue 4: Slow Performance

**Causes:**
- Testing too many sources at once
- Slow network connection
- Rate limiting

**Solutions:**
- Test in smaller batches
- Increase timeout values
- Use caching for repeated tests
- Test during off-peak hours

---

## 💡 Best Practices

### 1. Regular Monitoring Schedule

**Daily:**
- Check dashboard overview
- Verify core services online
- Quick FastAPI endpoint test

**Weekly:**
- Run force test on all sources
- Review analytics
- Check for new failures

**Monthly:**
- Export and analyze historical data
- Identify patterns in failures

### 2. Use Auto-Heal Strategically

**Enable For:**
- External APIs with known intermittent issues
- Sources behind CDNs
- APIs with rate limits

**Disable For:**
- Internal services (faster feedback)
- Critical APIs (immediate failure notification)
- Debugging sessions

### 3. Custom Testing Workflow

**Before Integration:**
1. Test new API in custom test tab
2. Verify response format
3. Check authentication
4. Test rate limits

**For Debugging:**
1. Use custom test with exact parameters
2. Try different headers
3. Increase retries
4. Check response details

### 4. Performance Optimization

**Tips:**
- Cache frequently accessed data
- Adjust timeouts based on provider
- Use appropriate retry counts
- Monitor and identify slow sources
