📊 Monitoring & Analytics

Production Metrics

The system provides comprehensive monitoring across multiple dimensions:

System Metrics

• Response Time: 95th percentile < 100ms
• Throughput: 1000+ requests/second
• Availability: 99.9% uptime SLA
• Error Rate: < 0.1% for 4xx/5xx responses

Security Metrics

• Contracts Analyzed: Real-time tracking
• Vulnerabilities Detected: By severity and type
• False Positive Rate: < 0.3%
• Detection Accuracy: 99.7%

Business Metrics

• User Engagement: Transaction protection usage
• Risk Prevention: Potential losses prevented
• Performance Impact: dApp interaction latency
• Knowledge Base Growth: Continuous learning metrics

Dashboard Examples

# Grafana dashboard queries
# Response time 95th percentile
histogram_quantile(0.95, rate(http_request_duration_seconds_bucket[5m]))

# Vulnerability detection rate
rate(vulnerabilities_detected_total[1h])

# System resource utilization
(1 - avg(rate(node_cpu_seconds_total{mode="idle"}[5m]))) * 100
