Frequently Asked Questions

What should I monitor in Kubernetes?
Monitor the four golden signals: latency, traffic, errors, and saturation. At the cluster level, track node CPU/memory, pod restarts, and pending pods. At the application level, monitor request rates, error rates, and response times.
Is Prometheus enough for Kubernetes monitoring?
Prometheus with Grafana covers most monitoring needs for small to medium clusters. For larger deployments, consider adding Thanos or Cortex for long-term storage, and tools like Jaeger for distributed tracing.
How do I set up alerts for Kubernetes?
Use Prometheus Alertmanager with alerting rules. Start with critical alerts: node not ready, pod CrashLoopBackOff, high error rates, and disk pressure. Route alerts to Slack, PagerDuty, or email based on severity.
