Flags an ALB instance as non-compliant when its 5xx error rate reaches or exceeds a specified threshold for at least 8 hours within a given time range (default: last 7 days). Does not apply to instances not connected to Cloud Monitor or without monitoring data. This check uses the Cloud Monitor monitoring data API and consumes the free quota of the basic Cloud Monitor service. To ensure check quality, enable Hybrid Cloud Monitoring. For billing details, see Cloud Monitor billing.
