Start monitoring your Kubernetes cluster with Prometheus and Grafana

Start monitoring your Kubernetes cluster with Prometheus and Grafana. This article will cover how to get those metrics using Prometheus and Grafana. This walkthrough also uses Pop!_OS 20.04, Helm 3, Minikube 1.14.2, and Kubernetes 1.19.

Before you can measure chaos, you need to know what your system's steady state looks like. Learn how in the second article in this series about chaos engineering.

In my introductory article about chaos engineering, one of the main things I covered was the importance of getting the steady state of your working Kubernetes cluster. Before you can start causing chaos, you need to know what the cluster looks like in a steady state.

This article will cover how to get those metrics using Prometheus and Grafana. This walkthrough also uses Pop!_OS 20.04, Helm 3, Minikube 1.14.2, and Kubernetes 1.19.

Configure Minikube

Install Minikube in whatever way makes sense for your environment. If you have enough resources, I recommend giving your virtual machine a bit more than the default memory and CPU power:

$ minikube config set memory 8192
❗ These changes will take effect upon a minikube delete and then a minikube start
$ minikube config set cpus 6
❗ These changes will take effect upon a minikube delete and then a minikube start
