* `allocator_allocated`: Total bytes allocated form the allocator, including internal-fragmentation. Normally the same as `used_memory`.
* `allocator_active`: Total bytes in the allocator active pages, this includes external-fragmentation.
* `allocator_resident`: Total bytes resident (RSS) in the allocator, this includes pages that can be released to the OS (by `MEMORY PURGE`, or just waiting).
* `allocator_muzzy`: Total bytes of 'muzzy' memory (RSS) in the allocator. Muzzy memory is memory that has been freed, but not yet fully returned to the operating system. It can be reused immediately when needed or returned to the OS when system pressure increases.

* `mem_not_counted_for_evict`: Used memory that's not counted for key eviction. This is basically transient replica and AOF buffers.
* `mem_clients_slaves`: Memory used by replica clients - Starting Redis 7.0, replica buffers share memory with the replication backlog, so this field can show 0 when replicas don't trigger an increase of memory usage.
* `mem_clients_normal`: Memory used by normal clients
