Elasticache

Amazon ElastiCache is a cloud-caching service that increases the performance, speed, and redundancy with which applications can retrieve data by providing an in-memory database caching system.

aws.elasticache.CPUUtilization

The percentage of CPU utilization.

When reaching high utilization and your main workload is from read requests, scale your cache cluster out by adding read replicas. If the main workload is from write requests, scale up by using a larger cache instance type.

For more information, refer to the ElastiCache documentation.

aws.elasticache.SwapUsage

The amount of swap space used on the host.

If swap is being utilized, the node probably needs more memory than is available and cache performance may be negatively impacted. Consider adding more nodes or using larger ones to reduce or eliminate swapping.
