AWS Integration - ElastiCache

Mackerel supports obtaining and monitoring Amazon ElastiCache metrics in AWS Integration. When integrating with AWS Integration, billable targets are determined using the conversion 1 Node = 1 Micro Host. In addition to this, depending on the number of metrics retrieved, you may be charged for exceeding the maximum number of metrics per micro host.

Please refer to the following page for AWS Integration configuration methods and a list of supported AWS services.
AWS Integration

Obtaining metrics

The metrics obtainable with AWS Integration’s ElastiCache support are as follows. For Metric explanations, refer to the AWS help pages (host level metrics, Memcached, and Redis).

The maximum number of metrics obtainable is 41 with Memcached, and 50 with Redis.
