A Hitchhiker's Guide to Observing Java Applications in Kubernetes

Explore various aspects of Kubernetes observability and discover multiple open-source solutions from the CNCF landscape in this 40-minute conference talk at Devoxx Greece 2024. Learn about tools that query the Kubernetes API with user-friendly UIs, sidecar-based and eBPF-based service meshes, and application-side logging and monitoring solutions. Gain insights into the trade-offs between configuration complexity, runtime overhead, and information quality for each observability level. Through live demonstrations, understand which tooling best suits different purposes when monitoring Java applications in Kubernetes clusters, covering options like Skooner, k9s, Kiali, Hubble UI, OpenTelemetry, fluentd, Jaeger, and Grafana.
