CPU Utilization Low Triage Guide

0) Understand: Low CPU utilization on ElastiCache clusters could mean overprovisioning or low workload demand. 1) Validate: Verify CloudWatch CPUUtilization for the cluster. Collect metrics using AWS CloudWatch. Required data points can be retrieved manually via the CloudWatch dashboard. The policy runs on schedule. 2) Triage: If unresolved, overprovisioning may continue to incur unnecessary costs. Rarely affects other services. 3) Act: Consider rightsizing or decommissioning the cluster, depending on workload analysis. 4) Reflect: If the alert doesn't match usage patterns, adjust the CPU threshold or exclude clusters with known low utilization periods.
