QuasarDB for Grafana


QuasarDB is a high performance, limitless, time series database built to handle the most demanding use cases.

This is the official QuasarDB Grafana Data Source plugin. It extends QuasarDB’s support to allow integration with the Grafana analytics and monitoring platform.

QDB Grafana Dashboard


This documentation assumes you have:

  • Grafana installed and running.
  • Both the QuasarDB daemon qdbd and the REST API qdb_rest running.


The easiest way to install the plugin is via the Grafana CLI

grafana-cli --pluginUrl plugins install qdb-grafana-datasource

Alternatively, you can clone the git repository to your Grafana plugins directory (this is usually /var/lib/grafana/plugins on Linux-based systems)

cd /var/lib/grafana/plugins
git clone

Finally, restart your Grafana server and the plugin will be added automatically.


Navigate your web browser to Grafana’s datasource configuration, and click Add data source. You will see QuasarDB as one of the available data sources.

It is recommended to leave Access set to Server (Default) unless you specifically know otherwise.

If your cluster is not secured you just need to fill in the REST API URL (default is http://localhost:40080) into the URL field as shown below:

Unsecured Configuration

If your cluster is secured make sure to use the secure REST API URL (default is https://localhost:40493) when filling in the URL field.

You may need to check Skip TLS Verify under Auth settings if you are using a self-signed TLS certificate.

Check the Use Secure Cluster checkbox and fill in the User name and User secret fields using the information found in your user private key file as shown below:

Unsecured Configuration

After you are done, click Save & Test and you are ready to starting creating visualizations using QuasarDB.


You can add a visualization using QuasarDB by selecting the QuasarDB Data Source when creating a new visualization.

Which result format you need will be specified by the visualization you are using, but Time series is a most common format.

When defining a query for your visualization you should specify whether you was like to format the result as either Time series or a Table by selecting an option from the FORMAT AS dropdown in the query editor as shown below:

Query Editor Format As

In additional to normal query syntax you can use the $__range and $__interval variables provided by Grafana.

For example the query:


Could be written to use Grafana's variables like this:

SELECT * FROM IN $__range GROUP BY $__interval

For information on query syntax see our docs for more information.
