Hands-On Microservices with Kubernetes

Metrics

Kubernetes comes with cAdvisor (https://github.com/google/cadvisor), which is a tool for collecting container metrics integrated into the kubelet binary. Kubernetes used to provide a metrics server called heapster that required additional backends and a UI. But, these days, the best in class metrics server is the open source Prometheus project. If you run Kubernetes on Google's GKE, then Google Cloud Monitoring is a great option that doesn't require additional components to be installed in your cluster. Other cloud providers also have integration with their monitoring solutions (for example, CloudWatch on EKS).
