Introduction to SRE Metrics
 What are SRE Metrics?
 Why is monitoring crucial?
 Improves reliability, performance, and availability
• Helps in proactive issue resolution.

(SLOs) & (SLIs)
 SLO: The target reliability level (e.g., 99.9% uptime)
• SLI: Measurable values (e.g., request latency, error 
rate)

Key Metric #1 - Availability
 Ensures the service is accessible to users
 Formula: Availability = (Uptime / Total Time) × 100
• Tools: Prometheus, Grafana, Google Cloud 
Monitoring

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

Key Metric #4 - Saturation
 Measures resource utilization (CPU, 
Memory, Disk)
• Helps prevent system overload and failures

Key Metric #5 - MTTR & MTBF
 MTTR (Mean Time to Recovery): Time 
to restore service after failure
• MTBF (Mean Time Between Failures): 
Duration between incidents

Conclusion & Best Practices
 Regularly review metrics and set alerts
 Automate monitoring and incident 
response
• Focus on user experience and reliability
