A Hitchhiker's Guide to CNCF/OSS Observability Solutions for Kubernetes

Explore the world of Kubernetes observability in this comprehensive tutorial that delves into various CNCF and open-source solutions. Begin with tools that query the Kubernetes API and provide user-friendly interfaces like Skooner and k9s. Progress to sidecar-based and eBPF-based service meshes, including Istio/Kiali and Cilium/Hubble UI. Conclude with application-side logging and monitoring using tools such as OpenTelemetry, Fluentd, Jaeger, and Grafana. Gain insights into the trade-offs between configuration complexity, runtime overhead, and information quality for each observability level. Through live demonstrations, learn to select the most appropriate tooling for specific use cases, enabling you to effectively monitor and manage your Kubernetes clusters and applications.
