Pre-requisites

Setup on Kubernetes

Install Grafana

  1. Add the Grafana Helm repo:

    1. helm repo add grafana https://grafana.github.io/helm-charts

  2. Install the chart:

    1. helm install grafana grafana/grafana -n dapr-monitoring

    Note

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

    1. helm install grafana grafana/grafana -n dapr-monitoring --set persistence.enabled=false

  3. Retrieve the admin password for Grafana login:

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

    You will get a password similar to cj3m0OfBNx8SLzUlTx91dEECgzRlYJb60D2evof1%. Remove the % character from the password to get cj3m0OfBNx8SLzUlTx91dEECgzRlYJb60D2evof1 as the admin password.

  4. Validation Grafana is running in your cluster:

    1. kubectl get pods -n dapr-monitoring
    3. NAME                                                READY   STATUS       RESTARTS   AGE

Configure Prometheus as data source

First you need to connect Prometheus as a data source to Grafana.

  1. Port-forward to svc/grafana:

    1. kubectl port-forward svc/grafana 8080:80 -n dapr-monitoring
    3. Forwarding from 127.0.0.1:8080 -> 3000
    4. Forwarding from [::1]:8080 -> 3000
    5. Handling connection for 8080
    6. Handling connection for 8080

  2. Open a browser to http://localhost:8080

  3. Login to Grafana

    • Username = admin
    • Password = Password from above

  4. Select Configuration and Data Sources

  5. Add Prometheus as a data source.

  6. Get your Prometheus HTTP URL

    The Prometheus HTTP URL follows the format http://<prometheus service endpoint>.<namespace>

    Start by getting the Prometheus server endpoint by running the following command:

    1. kubectl get svc -n dapr-monitoring
    3. NAME                                 TYPE        CLUSTER-IP        EXTERNAL-IP   PORT(S)             AGE
    4. dapr-prom-kube-state-metrics         ClusterIP   10.0.174.177      <none>        8080/TCP            7d9h
    5. dapr-prom-prometheus-alertmanager    ClusterIP   10.0.255.199      <none>        80/TCP              7d9h
    6. dapr-prom-prometheus-node-exporter   ClusterIP   None              <none>        9100/TCP            7d9h
    7. dapr-prom-prometheus-pushgateway     ClusterIP   10.0.190.59       <none>        9091/TCP            7d9h
    8. dapr-prom-prometheus-server          ClusterIP   10.0.172.191      <none>        80/TCP              7d9h
    9. elasticsearch-master                 ClusterIP   10.0.36.146       <none>        9200/TCP,9300/TCP   7d10h
    10. elasticsearch-master-headless        ClusterIP   None              <none>        9200/TCP,9300/TCP   7d10h
    11. grafana                              ClusterIP   10.0.15.229       <none>        80/TCP              5d5h
    12. kibana-kibana                        ClusterIP   10.0.188.224      <none>        5601/TCP            7d10h

    In this guide the server name is dapr-prom-prometheus-server and the namespace is dapr-monitoring, so the HTTP URL will be http://dapr-prom-prometheus-server.dapr-monitoring.

  7. Fill in the following settings:

    • Name: Dapr
    • HTTP URL: http://dapr-prom-prometheus-server.dapr-monitoring
    • Default: On

  8. Click Save & Test button to verify that the connection succeeded.
