The Grafana Dashboard Alert

Grafana is an open source visualization tool that allows you to create and edit dashboards.

Modules can create their own services to write custom alerts or create alerts in Grafana for services that they wish to monitor.

When alerts are generated, they are displayed in the Suite Admin's module details page > Alerts tab. When you acknowledge active alerts, they are move to the Dismissed tab and stored there for 60 days before they are deleted.

The Alerts tab lists two categories of alerts which are driven from Grafana.

  • Active Alerts: Each active alert lists the following details:
