Creating and Updating an Application Dashboard

Observing chaos injections and deriving insights from the chaos events is the core part of Chaos Observability. Whenever a chaos workflow run is performed its impact may be observed across different services and applications. Application dashboards provide a systematic visualization of all such events along with the performance of the individual service/application.

Before you begin#

To configure an application dashboard, you must first add a data source. To learn more about data sources click here

If no data source is available, a banner on the application dashboard tab requests you to add it before configuring a dashboard.

If a data source becomes inactive after dashboard creation then you will be requested to either reconfigure the dashboard with another data source or update the existing data source.

Table for configured dashboards#

All the configured dashboards are listed under the Dashboards table. The table provides you all the details related to the dashboard like the name of the dashboard, the agent with which it has been connected, type of the dashboard, connected data source type and the last date it was opened.

For all the dashboards listed in the table, you can filter the dashboard with respect to agent name, dashboard-type and time period for dashboard creation.

On clicking on more options, you can select View to open the dashboards, click on configure to make changes in the existing dashboard, you can also download the dashboard in JSON format and click on Delete to remove the dashboard.
