4.2 Configure Grafana Dashboard Alerts

What

Dashboard alerts notify you when a graph crosses a condition you define.

Alerts are available only for visualizations of type Graph.

When/Why

Use an existing custom dashboard graph as the data source for an alert.

How

Open the graph's drop-down menu and select Edit:

Select the Notification icon and configure the alert condition. In this example, the alert triggers when the total device count exceeds 20.

Add a message that tells recipients what crossed the threshold and what they should check next.
