Apache Pulsar Grafana Dashboard

FOSSA Status

The Grafana dashboard docker image is available at Docker Hub.

To use this dashboard image, provide the following environment variables:

  • PULSAR_PROMETHEUS_URL: The HTTP URL that points to your prometheus service. For example, http://<prometheus-host>:9090.
  • PULSAR_CLUSTER: The pulsar cluster name. The cluster name is aligned with your prometheus configuration. See Prometheus for more details.


To display the metrics correctly with this dashboard, configure your Prometheus server to collect metrics from Pulsar correctly.

  1. Attach your prometheus service to an extra label - cluster. The cluster name is aligned with the PULSAR_CLUSTER name you have provided to the grafana dashboard.

        cluster: <your-cluster-name>
  2. Make sure the job name of each component is the same with the ones in this dashboard.

    • job proxy: the machines that run pulsar proxies.
    • job broker: the machines that run pulsar brokers.
    • job bookie: the machines that run bookies.
    • job zookeeper: the machines that run zookeeper.
    • job node_metrics: all the machines of the pulsar cluster.

How to configure your prometheus server to collect the metrics of a Pulsar cluster, refer to example prometheus config.


Use this Grafana Dashboard on a standalone cluster.

Start Pulsar Standalone

Download the pulsar binary and follow the instruction to start a standalone cluster on your computer.

Start Prometheus

  1. Generate a Prometheus config file.

Two options are available to generate a prometheus config file.

  • Copy the template file prometheus/standalone.yml.template, and replace {{ STANDALONE_HOST }} with your IP address of the machine running pulsar standalone.
  • Install j2cli. j2cli is a command-line tool for templating Jinja2 template files. You can use j2cli to generate a Prometheus config file from the standalone template.
$ STANDALONE_HOST="$(ifconfig | grep "inet " | grep -v | awk '{ print $2 }')" j2 prometheus/standalone.yml.template > /tmp/standalone.prometheus.yml

In Ubuntu, set STANDALONE_HOST as below.

$ STANDALONE_HOST="$(ifconfig | grep "inet " | grep -v | awk '{ print $2 }' | awk -F ':' '{ print $2 }' | awk 'NR==2')" j2 prometheus/standalone.yml.template > /tmp/standalone.prometheus.yml

If it doesn't work properly, you can set the IP manually.

  1. Run Prometheus with the generated prometheus config file.
docker run -p 9090:9090 -v /tmp/standalone.prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

After running the prometheus successfully, you have access to http://localhost:9090/targets, where you can see prometheus detecting all pulsar components, shown as follows.

Start Grafana Dashbard

When you have a Pulsar standalone and a Prometheus server connecting to the Pulsar standalone, you can start with the Grafana Dashboard.

export PULSAR_PROMETHEUS_URL=http://$(ifconfig | grep "inet " | grep -v | awk '{ print $2 }'):9090
export PULSAR_CLUSTER=standalone
docker run -it -p 3000:3000 -e PULSAR_PROMETHEUS_URL="${PULSAR_PROMETHEUS_URL}" -e PULSAR_CLUSTER="${PULSAR_CLUSTER}" streamnative/apache-pulsar-grafana-dashboard:latest 

In Ubuntu, set PULSAR_PROMETHEUS_URL in this way.

export PULSAR_PROMETHEUS_URL=http://$(ifconfig | grep "inet " | grep -v | awk '{ print $2 }' | awk -F ':' '{ print $2 }' | awk 'NR==2'):9090

If it doesn't work properly, you can set the IP manually.

Access the Grafana Dashboard at http://localhost:3000. The default user name is admin, the default password is happypulsaring, and they are set in the conf/grafana.ini file.

Import dashboard to your Grafana installation

First of all, you need to make sure your prometheus is configured to attach cluster label as described in section #prometheus.

If you already have a grafana installation and you would like to import the dashboards to your grafana installation.

You can run scripts/generate_dashboards.sh to generate a datasource and the dashboard files that you can use to import to your installation.

./scripts/generate_dashboards.sh <prometheus-url> <clustername>
  • <prometheus-url>: The url points to your prometheus servcie. E.g. http://localhost:9090
  • <clustername>: Your pulsar cluster name.

The datasource yaml file and dashboard json files will be generated under target/datasources and target/dashboards. You can then import those files into your grafana installation.


The Grafana Docker Image contains the following built-in dashboards for different components in an Apache Pulsar cluster. These dashboards are:

  • Overview: This renders the overview health of a Pulsar cluster.
  • Messaging Metrics: This renders the metrics related to Pulsar messaging (e.g. producers, consumers, msg backlog and so on).
  • Proxy Metrics: This renders the metrics related to Pulsar proxies if you have run proxies in your Pulsar clusters. This doesn't apply to a standalone cluster.
  • Bookie Metrics: This renders the metrics related to Bookies. This doesn't apply to a Standalone cluster since a Pulsar standalone doesn't expose bookie metrics.
  • ZooKeeper: This renders the metrics related to ZooKeeper cluster.
  • JVM Metrics: This renders the jvm related metrics of all the components in a Pulsar cluster (For example, proxies, brokers, bookies, and so on).

System metrics are rendered in the Node Metrics dashboard and some portions in Overview dashboard. The system metrics used by these dashboards are collected by Prometheus Node Exporter. So you have to configure each pulsar machine to run node exporter, and configure your Prometheus to scrape the metrics from node exporters.

Build Your Own Image (Optional)

To customize and build your own dashboard image, issue the following command:
