Triage Guide: LOW_TRAFFIC

Understand​

This alarm indicates your AWS Application Load Balancer is processing fewer bytes than expected, suggesting underutilization.

Validate​

Check CloudWatch metrics to confirm low traffic. Retrieve metrics via the AWS Management Console or AWS CLI. The policy runs daily.

Triage​

Impact may include overprovisioning costs. If unaddressed, the misallocation of resources continues. No downtime is expected for remediation.

Act​

Consider resizing or reconfiguring the ALB, or redirecting traffic to optimize usage.

Reflect​

If false positives arise frequently, modify the averageBytesThreshold or disable the policy for specific ALBs.
