Crash Course in Kubernetes Monitoring

Dive into a 30-minute crash course on Kubernetes monitoring, exploring cloud-native solutions like Prometheus and Grafana. Learn how to instrument applications, gather metrics, and leverage high-level aggregate information for effective monitoring of Kubernetes deployments. Discover the importance of microservices in enabling modularity at technical and business levels, and understand emerging patterns for managing them with Kubernetes. Gain insights into monitoring architecture, metrics recording with Drop Wizard, setting up Prometheus for data collection and querying, configuring alerts, and creating Grafana panels. Explore additional topics such as annotations, Service Monitor, Kube state metrics, and Prometheus exporters. By the end of this Devoxx conference talk by Robert Munteanu, Senior Computer Scientist at Adobe, acquire the knowledge to implement a comprehensive monitoring setup for your Kubernetes environment.
