Introduction to SRE Metrics • What are SRE Metrics? • Why is monitoring crucial? • Improves reliability, performance, and availability • Helps in proactive issue resolution. +91-7032290546 www.visualpath.in
(SLOs) & (SLIs) • SLO: The target reliability level (e.g., 99.9% uptime) • SLI: Measurable values (e.g., request latency, error rate) +91-7032290546 www.visualpath.in
Key Metric #1 - Availability • Ensures the service is accessible to users • Formula: Availability = (Uptime / Total Time) × 100 • Tools: Prometheus, Grafana, Google Cloud Monitoring +91-7032290546 www.visualpath.in
Key Metric #2 - Latency • Measures response time of a system • Types: p50, p90, p99 latency • Goal: Minimize response time for better user experience +91-7032290546 www.visualpath.in
Key Metric #3 - Error Rate • Tracks failed requests vs. total requests • High error rates indicate service instability • Example:HTTP 500 errors, failed database queries +91-7032290546 www.visualpath.in
Key Metric #4 - Saturation • Measures resource utilization (CPU, Memory, Disk) • Helps prevent system overload and failures +91-7032290546 www.visualpath.in
Key Metric #5 - MTTR & MTBF • MTTR (Mean Time to Recovery): Time to restore service after failure • MTBF (Mean Time Between Failures): Duration between incidents +91-7032290546 www.visualpath.in
Conclusion & Best Practices • Regularly review metrics and set alerts • Automate monitoring and incident response • Focus on user experience and reliability +91-7032290546 www.visualpath.in
