Settings API - Anomaly detection for infrastructure- Host schema table
Anomaly detection for infrastructure: Host (builtin:anomaly-detection.infrastructure-hosts)
Dynatrace automatically detects infrastructure-related performance anomalies such as high CPU saturation and memory outages. Use these settings to configure detection sensitivity, set alert thresholds, or disable alerting for hosts.
