This check monitors the memory of an Redis node. The monitored metrics are:

- Bytes used for cache

- Memory usage

- Evictions - the number of keys that have been evicted due to the maxmemory limit

- Reclaimed - the total number of key expiration events

- Memory fragmentation - indicates the efficiency in the allocation of memory of the Redis engine

- Cache hit rate

To make this check work you have to configure the related special agent Amazon Web Services (AWS).
