Performance Analytics Dashboard

Performance Monitoring (`/admin/monitoring/performance`)

Key Metrics

The performance dashboard tracks:

1. Request Metrics

   • Total requests per second (RPS)
   • Request volume by endpoint
   • Response time percentiles (P50, P95, P99)

2. Error Tracking

   • Error rate percentage
   • Errors by status code (4xx, 5xx)
   • Error timeline and patterns

3. System Resources

   • CPU utilization percentage
   • Memory usage (heap total/used)
   • Disk space utilization

Performance Alerts

The system automatically alerts when:

• Response time P95 exceeds 2 seconds
• Error rate exceeds 5%
• CPU usage above 80% for 5+ minutes
• Memory usage above 85%
• Disk space below 15%

Database Monitoring

Connection Monitoring

• Active connections: Current database connection count
• Connection pool status: Available vs. used connections
• Query performance: Slow query detection and logging

Query Analysis

• Slow queries: Queries exceeding 1 second execution time
• Deadlock detection: Database deadlock identification
• Cache hit ratios: Database cache performance metrics
