Monitor ElastiCache with AWS metrics + native metrics
AWS ElastiCache is a fully managed in-memory caching service that allows users to choose between Redis and Memcached as its backend caching engine. It serves as a drop-in replacement for running these data stores yourself. Since a cache can have critical impact on an application's performance, it needs to be continuously monitored. Datadog has introduced a new ElastiCache integration that enables users to monitor ElastiCache metrics along with native metrics from the backing software: Redis or Memcache. This complete set of metrics provides a full view of your cache and includes key metrics such as number of commands processed, cache hits and misses, evictions, swap usage, current connections, number of nodes per cluster, replication lag, and CPU utilization. Additionally, native metrics for greater resolution are available directly from Redis or Memcached, providing more granular information about memory usage, memory fragmentation ratio, and latency. Custom tags can be used within Datadog to split, aggregate, or filter metrics, and all the events related to ElastiCache and your caching engine are recorded in Datadog's event stream for correlation with changes in performance throughout infrastructure.
