• SLI Measurable values (e.g., request latency,
  error rate)

Key Metric 2 - Latency

• Measures response time of a system
• Types p50, p90, p99 latency
• Goal Minimize response time for better user
  experience

Key Metric 3 - Error Rate

• Tracks failed requests vs. total requests
• High error rates indicate service instability
• Example HTTP 500 errors, failed database queries
