This is documentation for the next version of Grafana. For the latest stable release, go to the latest version.

Data sources

Data sources

Grafana can query and integrate with many different types of databases. This is done by adding a data source of the type you want to query or integrate with. When you have created and configured a data source you are ready to start exploring and visualizing data, either in Explore or in a new Dashboard. A dashboard is composed of panels, each panel contains a set of queries to one or more data sources.

You can also create new a alert rule from a data source query and have Grafana continuously evaluate it and notify you when things change.

You can also query data sources without building a dashboard by using the Explore feature.

Manage data sources

Only users with the organization administrator role can add or remove data sources. To access data source management tools in Grafana as an administrator, navigate to Configuration > Data Sources in the Grafana sidebar.

For details on data source management, including instructions on how to add data sources and configure user permissions for queries, refer to the administration documentation.

Use query editors

The InfluxDB query editor
The InfluxDB query editor

Each data source’s query editor provides a customized user interface that helps you write queries that take advantage of its unique capabilities. You use a data source’s query editor when you create queries in dashboard panels or Explore.

Because of the differences between query languages, each data source query editor looks and functions differently. Depending on your data source, the query editor might provide auto-completion features, metric names, variable suggestions, or a visual query-building interface.

For example, this video demonstrates the visual Prometheus query builder:

For general information about querying in Grafana, and common options and user interface elements across all query editors, refer to Query and transform data.

Built-in core data sources

These built-in core data sources are included in the Grafana documentation:

Special data sources

Grafana also includes three special data sources:

  • Grafana: A built-in data source that generates random walk data and can poll the Testdata data source. This helps you test visualizations and run experiments.
  • Mixed: An abstraction that lets you query multiple data sources in the same panel. When you select Mixed, you can then select a different data source for each new query that you add.
    • The first query uses the data source that was selected before you selected Mixed.
    • You can’t change an existing query to use the Mixed data source.
    • Grafana Play example: Mixed data sources
  • Dashboard: A data source that uses the result set from another panel in the same dashboard.
