```typescript
// Multi-browser monitoring across regions
const config = {
  browsers: ['chromium', 'firefox', 'webkit'],
  locations: ['us-east', 'us-west', 'eu-west', 'asia-pacific'],
  intervals: ['1m', '5m', '15m'],
  checks: ['api_health', 'user_flow', 'performance']
};
```

**Key Metrics**:
- Availability percentage
- Response times
- Transaction success rates
- Geographic performance

### Real User Monitoring (RUM)

**Features**:
- Core Web Vitals collection
- User journey tracking
- Error tracking
- Performance monitoring

```typescript
// RUM configuration
const rumConfig = {
  samplingRate: 0.1, // 10% of users
  features: {
    performanceMetrics: true,
    errorTracking: true,
    userJourney: true,
    customMetrics: true
  }
};
```

### Distributed Tracing

**Tool**: OpenTelemetry

**Instrumentation**:
- HTTP requests
- Database queries
- External API calls
- Google AI service calls
- Agent-to-agent communication

```typescript
// Trace Google AI inference
await tracing.traceAIInference('gemini-2.5-pro', async (span) => {
  const result = await geminiAPI.generateContent(prompt);
  span.setAttributes({
    'gemini.tokens.input': result.usage.promptTokens,
    'gemini.tokens.output': result.usage.candidatesTokens
  });
  return result;
});
```

### Custom Metrics & Dashboards

**Business Metrics**:
- Google AI service usage
- Video generation metrics
- Research pipeline performance
- User satisfaction scores

**Technical Metrics**:
- System resource utilization
- Application performance
- Error rates and patterns
- SLA compliance metrics

```typescript
// Record business metrics
metricsCollector.recordGeminiMetrics({
  model: 'gemini-2.5-pro',
  promptTokens: 150,
  completionTokens: 300,
  responseTime: 1200,
  success: true,
  userId: 'user123'
});
```

## 📈 SLA Compliance (99.9% Uptime)

### SLA Targets

| Metric | Target | Measurement Window |
|--------|--------|-------------------|
| **Availability** | 99.9% | Rolling 30 days |
| **Response Time** | < 2000ms | P95 over 5 minutes |
| **Error Rate** | < 0.1% | Rolling 1 hour |
| **Throughput** | > 100 req/min | Rolling 5 minutes |

### SLA Monitoring

```typescript
// Continuous SLA measurement
const slaConfig = {
  targets: {
    availability: 99.9,
    responseTime: 2000,
    errorRate: 0.1,
    throughput: 100
  },
  measurement: {
    window: 5, // 5-minute windows
    retention: 90 // 90 days
  }
};
```

### Escalation Procedures

**Level 1** (5 minutes): Warning alerts
**Level 2** (15 minutes): Critical alerts + Auto-scaling
**Level 3** (30 minutes): Incident creation + Failover

### SLA Credits

| Availability | Service Credit |
|-------------|----------------|
| < 99.9% | 10% |
| < 99.0% | 25% |
| < 95.0% | 100% |

## 🔧 Troubleshooting

### Common Issues

#### 1. E2E Tests Failing

**Problem**: Synthetic monitoring tests timeout
**Solution**:
```bash
# Increase timeout in configuration
# Check network connectivity
# Verify API endpoints are accessible
npm run monitoring:health
```

#### 2. SLA Violations

**Problem**: Availability drops below 99.9%
**Solution**:
```bash
# Check system health
npm run validate:sla

# Review recent incidents
npm run monitoring:health

# Check auto-scaling status
kubectl get pods # if using Kubernetes
```

#### 3. Performance Issues

**Problem**: Response times exceed SLA targets
**Solution**:
```bash
# Run performance analysis
npm run test:performance

# Check resource utilization
top
iostat

# Review distributed traces
# Check for database slow queries
```

#### 4. Monitoring System Down

**Problem**: Monitoring components unhealthy
**Solution**:
```bash
# Restart monitoring system
npm run monitoring:start

# Check component health
curl -s http://localhost:3001/monitoring/health | jq

# Review logs
tail -f logs/production-validation-setup.log
```

### Debug Commands
