获取在memcached中设置的所有密钥 [英] get all keys set in memcached

问题描述

我尝试了谷歌搜索，但没有发现太多，除了 PHP 支持 getAllKeys code> method ，这意味着它实际上可以做到这一点。

那么，如何在telnet会话中获得相同的结果呢？

我试过了 memcached备忘单和 Memcached telnet命令摘要，但它们都不起作用，并且我无法找到正确的方法来完成此操作。

PS：我正在执行此操作在开发中，所以可以假定由于设置了新键或其他这样的竞争条件而不会有问题。

解决方案

找到一种方法，感谢链接

a>（与原始的此处的Google小组讨论）

首先， Telnet 到您的服务器：

  telnet 127.0.0.1 11211 
  

接下来，列出项目以获取slab ID：

 
 stats项目
 STAT项目：3：number 1 
 STAT项目：3：年龄498 
 STAT项目：22：号码1 
 STAT项目：22：年龄498 
 END 
 

'items'之后的第一个数字是板ID。请求每个板块ID的缓存转储，并限制要转储的最大密钥数量：

 
 stats cachedump 3 100 
 ITEM views.decorators.cache.cache_header..cc7d9 [6 b; 1256056128 s] 
 END 
 
 stats cachedump 22 100 
 ITEM views.decorators.cache.cache_page..8427e [7736 b; 1256056128 s] 
 END 
 
 

How can I get all the keys set in my memcached instance(s)?

I tried googling, but didn't find much except that PHP supports a getAllKeys method, which means it is actually possible to do this somehow.

So, How can I get the same within a telnet session?

I have tried out all the retrieval related options mentioned in memcached cheat sheet and Memcached telnet command summary, but none of them work and I am at a loss to find the correct way to do this.

PS: I am currently doing this in development, so it can be assumed that there will be no issues due to new keys being set or other such race conditions happening.

解决方案

Found a way, thanks to the link here (with the original google group discussion here)

First, Telnet to your server:

telnet 127.0.0.1 11211

Next, list the items to get the slab ids:

stats items
STAT items:3:number 1
STAT items:3:age 498
STAT items:22:number 1
STAT items:22:age 498
END

The first number after ‘items’ is the slab id. Request a cache dump for each slab id, with a limit for the max number of keys to dump:

stats cachedump 3 100
ITEM views.decorators.cache.cache_header..cc7d9 [6 b; 1256056128 s]
END

stats cachedump 22 100
ITEM views.decorators.cache.cache_page..8427e [7736 b; 1256056128 s]
END
