Alerts

Overview

In this overview, we want to present two ways to receive alerts for control plane and Gardener managed system-components:

• Predefined Gardener alerts
• Custom alerts

Predefined Control Plane Alerts

In the shoot spec it is possible to configure emailReceivers. On this email address you will automatically receive email notifications for predefined alerts of your control plane. Such alerts are deployed in the shoot Prometheus and have visibility owner or all. For more alert details, shoot owners can use this visibility to find these alerts in their shoot Prometheus UI.

spec:
  monitoring:
    alerting:
      emailReceivers:
      - john.doe@example.com

For more information, see Alerting.

Custom Alerts – Federation

If you need more customization for alerts for control plane metrics, you have the option to deploy your own Prometheus into your shoot cluster.

Then you can use federation, which is a Prometheus feature, to forward the metrics from the Gardener managed Prometheus to your custom deployed Prometheus. Since as a shoot owner you do not have access to the control plane pods, this is the only way to get those metrics.

The credentials and endpoint for the Gardener managed Prometheus are exposed over the Gardener dashboard or programmatically in the garden project as a secret (<shoot-name>.monitoring).
