## Monitoring Dashboards & Queries

### Prometheus Queries
```promql
# Average session duration
avg(claude_code_session_duration_seconds)

# Code modification rate
rate(claude_code_lines_modified_total[5m])

# API cost per hour
sum(rate(claude_code_api_cost_total[1h]))

# Token usage efficiency
claude_code_output_tokens_total / claude_code_input_tokens_total

# Error rate percentage
(sum(rate(claude_code_errors_total[5m])) / sum(rate(claude_code_requests_total[5m]))) * 100
```

### Usage Analytics Queries
```sql
-- Daily active users
SELECT DATE(timestamp) as date, COUNT(DISTINCT user_uuid) as dau
FROM claude_code_sessions 
GROUP BY DATE(timestamp);

-- Most productive hours
SELECT HOUR(timestamp) as hour, AVG(lines_modified) as avg_lines
FROM claude_code_sessions 
GROUP BY HOUR(timestamp)
ORDER BY avg_lines DESC;

-- Cost analysis by team
SELECT organization_uuid, SUM(api_cost) as total_cost, AVG(api_cost) as avg_cost
FROM claude_code_usage 
GROUP BY organization_uuid;
```

patterns = analyzer.find_patterns(
    metrics=["session_duration", "lines_modified", "api_cost"],
    group_by=["user", "project", "time_of_day"]
)

# Generate optimization recommendations
recommendations = analyzer.optimize(
    target="cost_efficiency",
    constraints={"max_latency": "2s", "min_quality": 0.95}
)
```

    metrics = {
        'productivity_trend': analyze_productivity_changes(),
        'cost_efficiency': calculate_cost_trends(),
        'user_engagement': measure_engagement_levels(),
        'feature_usage': track_feature_adoption(),
        'performance_metrics': analyze_response_times()
    }
    
    recommendations = generate_optimization_recommendations(metrics)
    
    return {
        'metrics': metrics,
        'trends': identify_trends(metrics),
        'recommendations': recommendations,
        'alerts': check_threshold_violations(metrics)
    }
```

## Troubleshooting Common Issues

### Telemetry Not Working
```bash
# Debug telemetry configuration
echo $CLAUDE_CODE_ENABLE_TELEMETRY
echo $OTEL_EXPORTER_OTLP_ENDPOINT

# Test connectivity
curl -X POST $OTEL_EXPORTER_OTLP_ENDPOINT/v1/metrics \
  -H "Content-Type: application/json" \
  -d '{"test": "connectivity"}'

# Check logs
claude-code logs --filter="telemetry" --level="debug"
```

### Missing Metrics
```bash
# Verify metric export
claude-code metrics list --available
claude-code metrics test --metric="session_count"

# Check export intervals
echo $OTEL_METRIC_EXPORT_INTERVAL

# Validate configuration
claude-code config validate --section="telemetry"
```

### Performance Issues
```bash
# Analyze slow queries
claude-code perf-debug --slow-threshold="1s"

# Check resource usage
claude-code system-stats --monitoring="enabled"

# Optimize export settings
export OTEL_METRIC_EXPORT_INTERVAL=60000  # Increase interval
export OTEL_EXPORTER_OTLP_COMPRESSION=gzip  # Enable compression
```

## Best Practices

### 1. Monitoring Strategy
- **Start Simple**: Begin with basic session and cost tracking
- **Scale Gradually**: Add detailed metrics as needs grow
- **Privacy First**: Ensure sensitive data is excluded from telemetry
- **Regular Reviews**: Weekly analysis of trends and anomalies

### 2. Data Retention
- **Hot Data**: 7 days of detailed metrics for immediate analysis
- **Warm Data**: 30 days of aggregated data for trend analysis
- **Cold Data**: 1 year of summary metrics for historical comparison

### 3. Team Collaboration
- **Shared Dashboards**: Create team-specific monitoring views
- **Automated Reports**: Daily/weekly summary emails
- **Threshold Alerts**: Proactive notification of issues
- **Regular Reviews**: Monthly optimization meetings

      });
      setMetrics(data);
    };
    
    fetchMetrics();
    const interval = setInterval(fetchMetrics, 60000); // Update every minute
    
    return () => clearInterval(interval);
  }, []);
  
  return (
    <DashboardGrid>
      <MetricCard title="Active Sessions" value={metrics.sessions} />
      <MetricCard title="Daily Cost" value={`$${metrics.cost}`} />
