Explore and visualize your data in the Data Explorer. For both InfluxQL and Flux, Chronograf allows you to move seamlessly between using the builder or templates and manually editing the query; when possible, the interface automatically populates the builder with the information from your raw query. Choose between visualization types for your query.

To open the Data Explorer, click the Explore icon in the navigation bar:

Select local time or UTC (Coordinated Universal Time)

• In the upper-right corner of the page, select the time to view metrics and events by clicking one of the following:
  • UTC for Coordinated Universal Time
  • Local for the local time reported by your browser

Note: If your organization spans multiple time zones, we recommend using UTC (Coordinated Universal Time) to ensure that everyone sees metrics and events for the same time.

Explore data with InfluxQL

InfluxQL is a SQL-like query language you can use to interact with data in InfluxDB. For detailed tutorials and reference material, see our [InfluxQL documentation](/{{< latest "influxdb" "v1" >}}/query_language/).

1. Open the Data Explorer and click Add a Query.
2. To the right of the source dropdown above the graph placeholder, select InfluxQL as the source type.
3. Use the builder to select from your existing data and allow Chronograf to format the query for you. Alternatively, manually enter and edit a query.
4. You can also select from the dropdown list of Metaquery Templates. Metaqueries show information about a database, such as.
5. Click Show template values to display the calculated values in the template.

Explore data with Flux

Flux is InfluxData's new functional data scripting language designed for querying, analyzing, and acting on time series data. To learn more about Flux, see Getting started with Flux.

Note: Flux v0.7 is a technical preview included with InfluxDB v1.8. It is still in active development and many functions provided by InfluxQL and TICKscript have yet to be implemented.

1. Open the Data Explorer and click Add a Query.

2. To the right of the source dropdown above the graph placeholder, select Flux as the source type. The Schema, Functions, and Script panes appear.

3. Use the Schema pane to explore your available data. Click the + sign next to a bucket name to expand its content.

4. Use the Functions pane to view details about the available Flux functions.

5. Use the Script pane to enter your Flux query.

   • To get started with your query, click the Script Wizard. In the wizard, you can select a bucket, measurement, fields and an aggregate.

     

   For example, if you make the above selections, the wizard inserts the following script:

   from(bucket: "telegraf/autogen")
   |> range(start: dashboardTime)
   |> filter(fn: (r) => r._measurement == "cpu" and (r._field == "usage_system"))
   |> window(every: autoInterval)
   |> toFloat()
   |> percentile(percentile: 0.95)
   |> group(except: ["_time", "_start", "_stop", "_value"])
   

   • Alternatively, you can enter your entire script manually.

6. Click Run Script in the top bar of the Script pane. You can then preview your graph in the above pane.

Visualize your query

Select the Visualization tab at the top of the Data Explorer. For details about all of the available visualization options, see Visualization types in Chronograf.

Add queries to dashboards

To add your query and graph to a dashboard:

1. Click Send to Dashboard in the upper right.

2. In the Target Dashboard(s) dropdown, select at least one existing dashboard to send the cell to, or select Send to a New Dashboard.

   

3. Enter a name for the new cell and, if you created a new dashboard, the new dashboard.

4. Click Send to Dashboard(s).
