Elasticache Metrics

Elasticache instances can come in a few “flavors”, which means metrics are unique to each “flavor” of Elasticache.

Host-level metrics are present on both Memcached as well as Redis clusters
Memcached metrics are available only on Memcached clusters, Memcached 1.4.14 metrics are only available on Memcached clusters using at least version 1.4.14
Redis metrics are present only on Redis clusters.
