Response Time Tracker

Implement comprehensive response time tracking and optimization.

Tracking Areas

1. API Endpoints: HTTP request/response times
2. Database Queries: Query execution times
3. External Services: Third-party API latency
4. Frontend Rendering: Page load and render times
5. Background Jobs: Async task execution times

Metrics to Track

• P50, P95, P99 Percentiles: Response time distribution
• Average Response Time: Mean latency
• Max Response Time: Worst-case scenarios
• Time Series Data: Response time trends

Process

1. Identify all application endpoints and operations
2. Design response time instrumentation strategy
3. Implement timing middleware/decorators
4. Create monitoring dashboards
5. Define SLO thresholds
6. Generate optimization recommendations

Output

Provide:

• Response time instrumentation code
• Monitoring configuration
• Dashboard setup (Prometheus, Grafana, etc.)
• SLO definitions with percentile targets
• Alert rules for degraded performance
• Optimization strategies for slow endpoints
