Settings API - Kubernetes node anomaly detection schema table

Kubernetes node anomaly detection (builtin:anomaly-detection.kubernetes.node)

Dynatrace automatically detects a wide range of common Kubernetes-related issues. Use these settings to configure alerts relevant to your Kubernetes nodes. Changing thresholds resets the observation period. Additional information can be found on our documentation page.
