Freeable Memory Low Triage Guide

0) Understand: Low memory utilization may indicate an ElastiCache cluster size larger than needed. 1) Validate: Check CloudWatch FreeableMemory metrics for the cluster. Metrics are accessible via CloudWatch. This check is scheduled. 2) Triage: Persistently low memory usage could lead to cost inefficiencies. Impact on other services is minimal. 3) Act: Rightsizing the cluster might be appropriate for efficiency. 4) Reflect: If the alert is not actionable, consider adjusting the memory threshold or accounting for expected low memory usage periods.
