Using ES|QL

edit

The Elasticsearch Query Language, ES|QL, makes it easier to explore your data without leaving Discover.

In this tutorial we’ll use the Kibana sample web logs in Discover and Lens to explore the data and create visualizations.

Prerequisite

    ES|QL keywords are not case sensitive.

Let’s add geo.dest to our query, to find out the geographical destination of the visits, and limit the results.

    FROM kibana_sample_data_logs
| KEEP machine.os, machine.ram, geo.dest
| LIMIT 10

  2. Click ▶Run.

Let’s sort the data by machine ram and filter out the destination GB.

  1. Copy the query below:

    FROM kibana_sample_data_logs
| KEEP machine.os, machine.ram, geo.dest
| SORT machine.ram desc
| WHERE geo.dest != "GB"
| LIMIT 10

  2. Click ▶Run.

  3. Click Save to save the query and visualization to a dashboard.

To make changes to the visualization you can use the visualization drop-down. To make changes to the colors used or the axes, or click the pencil icon. This opens an in-line editor where you can change the colors and axes of the visualization.
