Set up Prometheus and Grafana in Kubernetes

This document describes how to install Prometheus and Grafana on a Kubernetes cluster which can then be used to view the Dapr metrics dashboards.

Watch this video for a demonstration of the Grafana Dapr metrics dashboards.

Prerequisites

Contents

Install Prometheus

  1. First create namespace that can be used to deploy the Grafana and Prometheus monitoring tools
kubectl create namespace dapr-monitoring
  1. Install Prometheus
helm repo add stable https://kubernetes-charts.storage.googleapis.com
helm repo update
helm install dapr-prom stable/prometheus -n dapr-monitoring

If you are Minikube user or want to disable persistent volume for development purposes, you can disable it by using the following command.

helm install dapr-prom stable/prometheus -n dapr-monitoring --set alertmanager.persistentVolume.enable=false --set pushgateway.persistentVolume.enabled=false --set server.persistentVolume.enabled=false
  1. Validation

Ensure Prometheus is running in your cluster.

kubectl get pods -n dapr-monitoring

NAME                                                READY   STATUS    RESTARTS   AGE
dapr-prom-kube-state-metrics-9849d6cc6-t94p8        1/1     Running   0          4m58s
dapr-prom-prometheus-alertmanager-749cc46f6-9b5t8   2/2     Running   0          4m58s
dapr-prom-prometheus-node-exporter-5jh8p            1/1     Running   0          4m58s
dapr-prom-prometheus-node-exporter-88gbg            1/1     Running   0          4m58s
dapr-prom-prometheus-node-exporter-bjp9f            1/1     Running   0          4m58s
dapr-prom-prometheus-pushgateway-688665d597-h4xx2   1/1     Running   0          4m58s
dapr-prom-prometheus-server-694fd8d7c-q5d59         2/2     Running   0          4m58s

Install Grafana

  1. Install Grafana
helm install grafana stable/grafana -n dapr-monitoring

If you are Minikube user or want to disable persistent volume for development purpose, you can disable it by using the following command.

helm install grafana stable/grafana -n dapr-monitoring --set persistence.enabled=false
  1. Retrieve the admin password for Grafana login

Note: Remove the % character from the password that this command returns. For example, the admin password is cj3m0OfBNx8SLzUlTx91dEECgzRlYJb60D2evof1.

kubectl get secret --namespace dapr-monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode
cj3m0OfBNx8SLzUlTx91dEECgzRlYJb60D2evof1%
  1. Validation

Ensure Grafana is running in your cluster (see last line below)

kubectl get pods -n dapr-monitoring

NAME                                                READY   STATUS    RESTARTS   AGE
dapr-prom-kube-state-metrics-9849d6cc6-t94p8        1/1     Running   0          4m58s
dapr-prom-prometheus-alertmanager-749cc46f6-9b5t8   2/2     Running   0          4m58s
dapr-prom-prometheus-node-exporter-5jh8p            1/1     Running   0          4m58s
dapr-prom-prometheus-node-exporter-88gbg            1/1     Running   0          4m58s
dapr-prom-prometheus-node-exporter-bjp9f            1/1     Running   0          4m58s
dapr-prom-prometheus-pushgateway-688665d597-h4xx2   1/1     Running   0          4m58s
dapr-prom-prometheus-server-694fd8d7c-q5d59         2/2     Running   0          4m58s
grafana-c49889cff-x56vj                             1/1     Running   0          5m10s

Next steps are to observe metrics with Grafana
