Monitor Pinot using Prometheus and Grafana

Here we will introduce how to monitor Pinot with Prometheus and Grafana in Kubernetes environment.


  • Kubernetes v1.16.5

  • HelmCharts v3.1.2

Deploy Pinot

Install Pinot helm repo

## Adding Pinot helm repo
helm repo add pinot
## Extract all the configurable values of Pinot Helm into a config.
helm inspect values pinot/pinot > /tmp/pinot-values.yaml

Configure Pinot Helm to enable Prometheus JMX Exporter

1. Configure jvmOpts:

Add JMX Prometheus Java Agent to controller.jvmOpts / broker.jvmOpts/ server.jvmOpts . Note that Pinot Docker image already packages jmx_prometheus_javaagent.jar.

Below config will expose pinot metrics to port 8008 for Prometheus to scrape.

  jvmOpts: "-javaagent:/opt/pinot/etc/jmx_prometheus_javaagent/jmx_prometheus_javaagent.jar=8008:/opt/pinot/etc/jmx_prometheus_javaagent/configs/pinot.yml -Xms256M -Xmx1G"

You can port forward port 8008 to local and access metrics though: http://localhost:8008/metrics

2. Configure service annotations:

Add Prometheus related annotations to enable Prometheus to scrape metrics.

  • controller.service.annotations

  • broker.service.annotations

  • server.service.annotations

  • controller.podAnnotations

  • broker.podAnnotations

  • server.podAnnotations

      "": "true"
      "": "8008"
    "": "true"
    "": "8008"

Deploy Pinot Helm

kubectl create ns pinot
helm install pinot pinot/pinot -n pinot --values /tmp/pinot-values.yaml

Deploy Prometheus

Once Pinot is deployed and running, we can start deploy Prometheus.

Similar to Pinot Helm, we will have Prometheus Helm and its config yaml file:

helm repo add prometheus-community
helm inspect values prometheus-community/prometheus > /tmp/prometheus-values.yaml

Configure Prometheus

Please remember to check the configs:

  • server.persistentVolume: data storage location/size limit/storage class

  • server.retention: how long to keep the data (default is 15d)

Deploy Prometheus

kubectl create ns prometheus
helm install prometheus prometheus-community/prometheus -n prometheus --values /tmp/prometheus-values.yaml

Access Prometheus

Port forward Prometheus service to local and open the page on localhost:30080

kubectl port-forward service/prometheus-server 30080:80 -n prometheus

Then we can query metrics Prometheus scrapped:

Deploy Grafana

Similar to Pinot Helm, we will have Grafana Helm and it's config yaml file:

helm repo add grafana
helm inspect values grafana/grafana > /tmp/grafana-values.yaml
  • Configure Grafana

  • Deploy Grafana

kubectl create ns grafana
helm install grafana grafana/grafana -n grafana --values /tmp/grafana-values.yaml
  • Get Password to access Grafana

kubectl get secret --namespace grafana grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo
  • Access Grafana dashboard

You can access it locally through port forwarding:

kubectl port-forward service/grafana 20080:80 -n grafana

Once open the dashboard, you can login with credential:


  • Add data source

Click on Prometheus and set HTTP URL to : http://prometheus-server.prometheus.svc.cluster.local

  • Configure Pinot Dashboard

Once data source is added, we can import a Pinot Dashboard:

A sample Pinot dashboard JSON is:

Now you can upload this file and select Prometheus as data source to finish the import

Then you can explore and make your own Pinot dashboard!
