ardb 中的类似命令，例如 memcached 中的stats，它给出了累计get，set操作的数量单独以及其他统计信息，例如misses？
e.g。在memcached中我可以执行stats命令，它给出了：
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_system 711.654138

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

使用这个我可以在最后一秒找出get操作的数量（通过在python中使用任何客户端库减去）。我想获得ardb每秒的get和set操作数。
我找到的唯一命令是info commandstats，它给出了：
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
info commandstats
$128
# Commandstats
cmdstat_get:calls=755061,usec=2009117846,usecpercall=2660
cmdstat_info:calls=23,usec=87805,usecpercall=3817
虽然这可以为我提供get个统计信息，但set和misses没有任何内容。是否有类似于ardb或某些黑客可以获取此信息？我使用rocksdb作为后端，需要一些用于从python监控的东西。
P.S 我因为低代表而无法创建ardb代码，也许其他人可以创建它？
