Kubernetes Observability

Short summary

Kubernetes observability requires a multi-tool approach with Prometheus for metrics, Grafana for dashboards, and Loki for logs. Real-world optimization requires careful tuning: adjust scrape intervals, manage label cardinality, and use S3 for long-term retention to control costs. Effective alerting is critical—define SLOs and error budgets rather than alerting on every metric to avoid noise that ops teams ignore.

• •Prometheus + Grafana + Loki is the recommended observability stack for Kubernetes
• •Optimize resource usage by tuning scrape intervals and managing label cardinality
• •Use SLO-based alerting and error budgets to reduce false positives
