Dashboards with Custom Query Language widget

The AQL panel is a dashboard element that allows you to create custom data displays using the CloudVision Advanced Query Language (AQL). This gives you complete control over what data the panel displays and how it displays it. You define the inputs and write the AQL query that feeds data to the panel. Further customization is available through creating a color mapping for the panel’s display, defining units, and decimal places among other options. You can create custom dashboards with AQL panels that are acutely relevant to your organization.

There are three elements:
  • Inputs: These are used by the AQL query to feed data to the AQL panel AQL
  • Panel: This is the display item within your dashboard and which uses the AQL query and any inputs to render a display AQL
  • Panel Visualization: The AQL panel has five ways to display the data fed to it (Table, Single Value, Bar Graph, Line Graph, and Donut), which each requires that the AQL query be formatted in a particular way. Each visualization can be further customized to change how it displays its data

The AQL panel is currently in beta and needs to be enabled as a setting. To enable the AQL panel, go to General Settings and turn on the toggle Beta Widgets under Features.

The Arista Support page titled Dashboards with Custom Query Language widget provides detailed configuration instructions and a tutorial about CloudVision Advanced Query Language (AQL).

Dashboard Preview

Data Plane CPU Utilization Breached Threshold

This event pushes a notification when CPU utilization for a single data plane core has exceeded the 80% default threshold. You may set an alternative threshold by configuring an event rule.

Confidence Check Events

You will now be alerted when CloudVision detects errors or potential errors in EVPN and VXLAN configurations.

EVPN Config Confidence Check Failed

This event raises an alert if there are any errors or potential errors with EVPN configuration. You are notified of the specific verification check that caused the confidence check failure.

All packages show the package name, version, and the number and type of components that are included. Hovering over an action icon or a dashboard icon displays the name of packaged components.

Packaging a Dashboard

For information about Packaging, refer to the Packaging TOI at https://www.arista.com/en/support/toi/cvp-2023-1-0/17503-packaging.

Once you have entered a package name, unique package ID, and a description, click Add Component and use the dropdown to select the dashboards to include in the package. Selected dashboards will appear under Contents.

Note: Dashboards and change control actions can be packaged together, though components in the same package should be closely related to one another.
