Beyond Alert Fatigue: Mastering SLO-Based Alerting in Microservices

Traditional threshold-based alerting creates alert fatigue, making it difficult for engineers to distinguish critical issues from noise in distributed systems. SLO-based alerting with error budgets solves this by shifting focus from arbitrary thresholds to actual service objectives and remaining capacity. Using OpenTelemetry and Prometheus, teams can implement precision alerting that prioritizes what truly impacts user experience while reducing operational toil.
