Kubernetes Observability Workshop

In this workshop, you will learn the basics of Monitoring and Observability with microservices and container clusters. The hands-on session includes Prometheus and Grafana, kube-prometheus, alerts/incidents, and customizations/scaling. We will discuss best practices with logs, traces, and how innovation with OpenTelementry and eBPF can help with advanced Observability workflows.
