Amazon MemoryDB for Redis is a durable, in-memory database service delivering both in-memory performance and multi-Availability Zone durability.
Enable this integration to see all your MemoryDB metrics in Datadog.
If you haven’t already, set up the Amazon Web Services integration first.

| aws.memorydb.keys_tracked (count) | The number of keys being tracked by Redis key tracking. This is limited by the parameter tracking-table-max-keys. |
| aws.memorydb.keyspace_hits (count) | The number of successful read-only key lookups in the main dictionary. |
