网络管理工具hyperic hq对memcached 的监控和管理

webmaster 在 2012-11-19 18:21 提交

Memcached 是一个高性能的分布式内存对象缓存系统，用于动态Web应用以减轻数据库负载。它通过在内存中缓存数据和对象来减少读取数据库的次数，从而提供动态、数据库驱动网站更快的运行速度。Memcached基于一个存储键/值对的hashmap。其守护进程（daemon ）是用C写的，但是客户端可以用任何语言来编写，并通过memcached协议与守护进程通信。但是它并不提供冗余（例如，复制其hashmap条目）；当某个服务器S停止运行或崩溃了，所有存放在S上的键/值对都将丢失。

网络管理工具Hyperic HQ支持对Memcached中间件的监控和管理。
