Grafana organizes queries in collapsible query rows.Įach query row contains a query editor and is identified with a letter (A, B, C, and so on). Grafana queries the data source and visualizes the data. If you’re creating a new dashboard, you’ll be prompted to select a data source when you add the first panel.Ĭlick Query options to configure the maximum number of data points you need.įor more information about query options, refer to Query options. When you create a panel, Grafana automatically selects the default data source.Įdit the panel to which you’re adding a query.Ĭlick the Data source drop-down menu and select a data source. Expressions: Uses the expression builder to create alert expressions.įor more information about expressions, refer to Use expressions to manipulate data.Ī query returns data that Grafana visualizes in dashboard panels.Query editor list: Lists the queries you’ve written.Query inspector button: Opens the query inspector panel, where you can view and optimize your query.

If it’s the latter, we’d expect they’ll be back up and running soon. Either we entered the id wrong (oops!), or Vimeo is down. There’s supposed to be a video here, but for some reason there isn’t. Query editors The InfluxDB query editorĮach data source’s query editor provides a customized user interface that helps you write queries that take advantage of its unique capabilities.īecause of the differences between query languages, each data source query editor looks and functions differently.ĭepending on your data source, the query editor might provide auto-completion features, metric names, variable suggestions, or a visual query-building interface.įor example, this video demonstrates the visual Prometheus query builder: Important: You must be familiar with a data source’s query language.įor more information, refer to Data sources. Grafana supports up to 26 queries per panel. You can configure query frequency and data collection limits in the panel’s data source options.
Grafana panels communicate with data sources via queries, which retrieve data for the visualization.Ī query is a question written in the query language used by the data source. Grafana supports many types of data sources.ĭata source queries return data that Grafana can transform and visualize.Įach data source uses its own query language, and data source plugins each implement a query-building user interface called a query editor.
