Checks whether the connection failure rate of an Application Load Balancer (ALB) instance stays below a specified threshold. The instance is non-compliant if the rate meets or exceeds the threshold for at least 8 hours within a configurable time range (default: 7 days).
Scenarios
Detects persistently high connection failure rates on ALB instances, helping you identify network connectivity issues or unhealthy backend services.
Risk level
Default risk level: High.
You can change the risk level as needed.
Detection logic
-
An ALB instance is non-compliant if its connection failure rate is greater than or equal to a specified value for at least 8 hours within a given time range. The rule does not apply if the instance is not connected to CloudMonitor or if no monitoring data is available. The default detection time range is the last 7 days. This check uses the CloudMonitor monitoring data API and consumes the free quota for Basic CloudMonitor. To ensure check quality, we recommend that you enable Hybrid Cloud Monitoring. For information about billing, see CloudMonitor billing.
