Fields

peak_allocated: usize

Peak memory consumed by Redis in bytes (see INFO’s used_memory_peak)

total_allocated: usize

Total number of bytes allocated by Redis using its allocator (see INFO’s used_memory)

startup_allocated: usize

Initial amount of memory consumed by Redis at startup in bytes (see INFO’s used_memory_startup)

replication_backlog: usize

Size in bytes of the replication backlog (see INFO’s repl_backlog_active)

clients_slaves: usize

The total size in bytes of all replicas overheads (output and query buffers, connection contexts)

clients_normal: usize

The total size in bytes of all clients overheads (output and query buffers, connection contexts)

cluster_links: usize

Memory usage by cluster links (Added in Redis 7.0, see INFO’s mem_cluster_links).

aof_buffer: usize

The summed size in bytes of AOF related buffers.

lua_caches: usize

the summed size in bytes of the overheads of the Lua scripts’ caches

functions_caches: usize

the summed size in bytes of the overheads of the functions’ caches

overhead_total: usize

The sum of all overheads, i.e. startup.allocated, replication.backlog, clients.slaves, clients.normal, aof.buffer and those of the internal data structures that are used in managing the Redis keyspace (see INFO’s used_memory_overhead)

keys_count: usize

The total number of keys stored across all databases in the server

keys_bytes_per_key: usize

The ratio between net memory usage (total.allocated minus startup.allocated) and keys.count

dataset_bytes: usize

The size in bytes of the dataset, i.e. overhead.total subtracted from total.allocated (see INFO’s used_memory_dataset)

dataset_percentage: f64

The percentage of dataset.bytes out of the net memory usage

peak_percentage: f64

The percentage of peak.allocated out of total.allocated

allocator_allocated: usize

allocator_active: usize

allocator_resident: usize

allocator_fragmentation_ratio: f64

allocator_fragmentation_bytes: isize

allocator_rss_ratio: f64

allocator_rss_bytes: isize

rss_overhead_ratio: f64

rss_overhead_bytes: isize

fragmentation: f64

See INFO’s mem_fragmentation_ratio

fragmentation_bytes: isize
