Getting periodic stats from redis

Question

Is there a similar command in redis like stats in memcached which gives the number of cumulative get, set ops separately.

e.g. in memcached I can do stats command and it gives:

STAT pid 1905
STAT uptime 87713
STAT time 1469108527
STAT version 1.4.25
STAT libevent 2.0.21-stable
STAT pointer_size 64
STAT rusage_user 300.101330
STAT rusage_system 711.654138
STAT curr_connections 18
STAT total_connections 4698
STAT connection_structures 739
STAT reserved_fds 40
STAT cmd_get 75355568
STAT cmd_set 3296663
STAT cmd_flush 0
STAT cmd_touch 0
STAT get_hits 44369791
STAT get_misses 30985777
STAT delete_misses 0
STAT delete_hits 0
STAT incr_misses 0
STAT incr_hits 0
STAT decr_misses 0
STAT decr_hits 0
STAT cas_misses 0
STAT cas_hits 0
STAT cas_badval 0
STAT touch_hits 0
STAT touch_misses 0
STAT auth_cmds 0
STAT auth_errors 0
STAT bytes_read 3615072874
STAT bytes_written 16173356516
STAT limit_maxbytes 3670016000
STAT accepting_conns 1
STAT listen_disabled_num 0
STAT time_in_listen_disabled_us 0
STAT threads 8
STAT conn_yields 1763246
STAT hash_power_level 17
STAT hash_bytes 1048576
STAT hash_is_expanding 0
STAT malloc_fails 0
STAT bytes 331012787
STAT curr_items 176322
STAT total_items 3296663
STAT expired_unfetched 0
STAT evicted_unfetched 0
STAT evictions 0
STAT reclaimed 0
STAT crawler_reclaimed 0
STAT crawler_items_checked 0
STAT lrutail_reflocked 0
END

Using this I can find out the number of get operations in the last second (by subtracting using any client library in python). I want to get the number of get and set operations per second for redis as well.

The only command that I have found is info and it has a stats section but it looks like this:

# Stats
slave_sync_total_commands_processed:0
slave_sync_instantaneous_ops_per_sec:0
total_commands_processed:11562138
instantaneous_ops_per_sec:0
total_connections_received:6139
rejected_connections:0
sync_full:0
sync_partial_ok:0
sync_partial_err:0
pubsub_channels:0
pubsub_patterns:0
expire_scan_keys:0

And I don't see how I can use this to find per second statistics for get and set ops. Is there any hack or command that can do this for redis? Preferably something that can be done programmatically from python.

Not a hack, but rather a bona fide kosher solution - use INFO ALL or just INFO CMDSTATS for that information (which is not provided by default).
