Question

在 memcached 中的 redis 中是否有类似stats的命令，它会提供累计get，set操作数分开。

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_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

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redis每秒获取和设置操作的次数。

我找到的唯一命令是info，它有一个 stats 部分，但它看起来像这样：

# 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

而且我也不知道如何使用它来查找获取和设置操作的每秒统计数据。是否有任何黑客或命令可以为 redis 执行此操作？最好是可以通过python以编程方式完成的事情。

不是黑客，而是真正的犹太洁食解决方案 - 使用<nav class="navbar navbar-inverse"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#">WebSiteName</a> </div> <div class="collapse navbar-collapse" id="myNavbar"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Home</a></li> <li><a href="#">Page 1</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> <ul class="nav navbar-nav navbar-right"> <li><a href="#"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li> <li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a></li> </ul> </div> </div> </nav>或仅INFO ALL获取该信息（默认情况下不提供）。

从redis获取定期统计信息
