The core of Kibana are the dashboards--an aggregation of widgets that are results of queries and aggregations.
You need an up-and-running Elasticsearch installation as we described in the Downloading and installing Elasticsearch recipe in Chapter 2, Downloading and Setup.
You also need a functional Kibana installation as described in the Installing Kibana and X-Pack recipe.
For managing Kibana dashboards, we will perform the following steps:
- We access the Discovery section of Kibana as shown in the following screenshot:
- After a few seconds, the default search frontend should appear. The default query is
*, which is executed against the_allfield.
The Kibana interface is divided into sections: Discovery, Visualize, Dashboards, Dev Tools, and Management are available in the opensource version of Kibana. The X-Pack adds Graph and Monitoring ones.
The dashboard top menu allows us to do as follows:
- Create a new dashboard starting from scratch via the New menu entry.
- Save the current dashboard / query giving it a name.
- Open the dashboards that you have already saved.
- Share a dashboard or a dashboard snapshot (with date/time value fixed) via a link.
- Generate a PDF from the current dashboard via the Reporting menu entry. To generate a report, your dashboard must be saved. The reporting entry is available only if X-Pack is installed.
- If you are using autorefresh dashboards, you can pause autorefresh via the pause icon. By clicking on the refresh interval, you can change it as shown in the following screenshot:
- Change/define the time interval range by clicking on the time range value.
Internally, the Kibana dashboards are stored in an Elasticsearch special index .kibana and in case of some asynchronous task the data is read from this index.
