Gianluca will dig deep into how to monitor Kubernetes with InfluxDB using lessons learned from building and running InfluxDB Cloud on Kubernetes. He will cover what metrics should be collected, when to use push and pull metric collection, and the role that Prometheus plays in any K8s monitoring environment.
