Add a query
A query returns data that Grafana visualizes in dashboards. When you create a panel, Grafana automatically selects the default data source.
Before you begin
To add a query:
Edit the panel to which you are adding a query.
Click the Query tab.
Click the Data source drop-down menu and select a data source.
Click Query options to configure the maximum number of data points returned by the query and how frequently you want the query to request data from the data source.
For more information about query options, refer to Reference: Query options.
Write the query.
The system queries the data source and presents the data in the visualization.
