libmemcached的安装  
  
访问其官方站：  
http://download.tangent.org/  
  
下载rpm包后安装，注意其最新的版本对glibc要求较高，如果不适用，建议用旧一点的版本  
  
比如： centos5.2可以使用较低的libmemcached-0.25-1.x86\_64.rpm  
  
安装完成后,memstat等命令可以用了

libmemcached是C客户端到memcached服务器的接口库。具有低内存占用率、线程安全、并提供对memcached功能的全面支持。它还 采用 多种命令行工具： memcat ， memflush ， memrm ， memstat ，并memslap （负载代） 。程序库一直在设计，让不同的散列方法对密钥，分割的钥匙，并使用统一的散列分配。  
  
  
memsat的例子:  
  
memstat --server 127.0.0.1

stats内容的一个说明：

**以下是引用片段：**

pid = process id  
uptime = number of seconds since the process was started  
time = current time  
version = memcached version  
rusage\_user = seconds the cpu has devoted to the process as the user  
rusage\_system = seconds the cpu has devoted to the process as the system  
curr\_items = total number of items currently in memcache  
total\_items = total number of items that have passed through the cache  
bytes = total number of bytes currently in use by curr\_items  
curr\_connections = total number of open connections to memcached  
connection\_structures = ???  
cmd\_get = total GET commands issued to the server  
cmd\_set = total SET commands issued to the server  
get\_hits = total number of times a GET command was able to retrieve and  
return data  
get\_misses = total number of times a GET command was unable to retrieve and  
return data  
bytes\_read = total number of bytes input into the server  
bytes\_written = total number of bytes written by the server  
limit\_maxbytes = total storage bytes available to the server.
