This Grafana data source plugin provides the ability to connect, query, and visualize SurrealDB stored information.


Besides the already installed and setup Grafana service -- for minimal version see plugin dependencies -- the following requirements must be met in order to use this plugin:

  • a deployed SurrealDB instance which is accessible through the network of your the Grafana service where this plugin will be installed

  • an existing SurrealDB namespace

  • an existing SurrealDB database

  • an optional existing SurrealDB scope

  • an existing SurrealDB user which has access to the namespace, database, and optionally the scope -- recommendation is to use a SurrealDB user which has the VIEWER role in order to perform exclusively read-only operations and do not alter any database state to maintain the data integrity

Since the plugin is used to query the contents of one or multiple SurrealDB tables, the existence of the tables in question is not required per default, because the plugin can be installed without an existing table and e.g. query and visualize database information as well.


The plugin can be installed through the user interface in the Grafana service itself or by using the command-line utility via:

$ grafana cli plugins install fiskaly-surrealdb-datasource

If the Grafana service was setup in a containerized context via e.g. docker-compose or started locally on a machine the plugin can be installed automatically for the Grafana instance during start-up by setting the following environment variable:



Following the data source management documentation and selecting this plugin in the add new data source connection page, the configuration of this plugin requires the following parameters to be setup:

  • Location of the WebSocket connection in form of a address:port schema (required, default value: localhost:8000)

  • Namespace to use (required, default value: default)

  • Database to use (required, default value: default)

  • Scope to use (optional)

  • Username for the user to interact with the SurrealDB instance (required, default value: root)

  • Password of the provided user to perform the authentication (required, default value: root)



The plugin defines three query modes: Raw, Log, and Metric For all modes the actual query is written in SurrealQL. Therefore, the Raw mode is representing the query results in a table view as preferred visualization type.

The Log mode changes the preferred visualization type to log-based view and allows to define/set the log Time and optional log Message column information.

For time series value-based visualizations, the plugin provides a Metric mode to represent the query results in a graph view as preferred visualization type. This mode allows to further configure/set the actual Data column to visualize the time series. Furthermore, based on the Data column there is an option to perform data grouping of a given Field as well as to perform different Rate computations in a given Interval.


Variable Query

This plugin provides raw query support for dashboard variables. The values of the first column in the query response are used for the result set of values for the defined variable in the dashboard.



The plugin consists of a frontend and a backend part. The frontend is written in TypeScript and provides two major components: (1) a ConfigEditor to setup and connect to a SurrealDB instance; and (2) a QueryEditor to write queries in SurrealDB Query Language (SurrealQL), configure the query mode, and interact with the backend part of the data source plugin.

The backend is written in Golang and provides a low-level connection through the SurrealDB WebSocket interface. After the successful connection and signin operation, all queries sent from the frontend part to the backend part are directly executed through the WebSocket connection using the custom query operation.

Since SurrealDB as well as Grafana support variables the plugin supports and performs the following variable resolving steps: (1) in the frontend part are all Grafana scope provided variables replaced; and (2) in the backend part defines the following plugin specific variables and replaces those before the query is send and executed on the SurrealDB instance:

  • $interval defined by the current query editor context
  • $now current timestamp in UTC taken at the beginning of the query execution
  • $from starting time as UTC timestamp of the current query editor context
  • $to ending time as UTC timestamp of the current query editor context

Provided dashboard variable-based query support.


Provided new groupBy functionality in metric query mode in order to perform data grouping for plain metric values as well as rate based functions. Updated plugin documentation and screenshots.


Enabled Grafana policy token for signing the data source plugin in order to be published in the Grafana plugin catalog.


Added additional optional scope for data source configuration. Provided the data source plugin handling to respect the hide query option. Improved internal stability of the plugin backend.


Initial release. Provides basic data source connection to a SurrealDB instance through the configuration of location, namespace, database, username, and password. The query editor provides a raw, log, and metric mode.
