Monitoring and Alerting for Reliability Questions

Design and implementation of monitoring and alerting systems that enable early detection of issues and effective incident response. Includes selection and instrumentation of key metrics such as latency, error rates, throughput, saturation, resource utilization and replication lag; defining service level objectives and service level indicators; setting alert thresholds and escalation paths to reduce noise; building dashboards and synthetic checks; integrating logs and traces for correlation; and designing on call and incident handling procedures including playbooks and post incident reviews. Also covers alert deduplication, prioritization, and strategies for auto remediation and health checks.
