An Application Load Balancer (ALB) instance is considered non-compliant if its 4xx error rate is greater than or equal to a specified value for at least 8 hours within a specific time range. This rule does not apply if the ALB instance is not connected to Cloud Monitor or if no monitoring data is available. The default detection time range is the last 7 days. This check uses the monitoring data API of Cloud Monitor and consumes the free quota for the basic Cloud Monitor service. To ensure detection quality, you can enable Hybrid Cloud Monitoring. For more information about the billing of Hybrid Cloud Monitoring, see Cloud Monitor billing.
