Prometheus and Grafana are a powerful duo when it comes to monitoring and visualizing metrics in a Kubernetes environment. By integrating Prometheus with Kubernetes, you gain the ability to record pod metrics in real-time and gain valuable insights into the performance of your applications. Additionally, by using Grafana as a visualization tool, you can create custom dashboards that provide a clear and concise overview of your cluster's health and application resource usage. One of the key benefits of using Prometheus with Kubernetes is the ability to configure horizontal pod autoscaling based on any metric collected by Prometheus. By leveraging the Prometheus adapter, you can easily set up autoscaling rules that help optimize resource utilization and ensure that your applications are running smoothly at all times. Overall, the combination of Prometheus and Grafana with Kubernetes offers a comprehensive monitoring solution that empowers users to make informed decisions and proactively address any issues that may arise within their cluster.
Setting up Prometheus and Grafana in a cluster is a breeze with Helm charts. To get started, simply install Helm and follow these commands to install the latest versions:
helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
kubectl create namespace metrics
helm install kube-prometheus-stack prometheus-community/kube-prometheus-stack -n metrics
helm install prometheus-adapter prometheus-community/prometheus-adapter --set prometheus.url=http://kube-prometheus-stack-prometheus.metrics.svc.cluster.local -n metrics
This installation includes Prometheus Stack, encompassing the Prometheus application and Grafana, alongside Prometheus Adapter. This adapter enables the utilization of Prometheus metrics for Horizontal Pod Autoscaling.
