使用Aspersa洞悉Linux系统软硬件配置

浏览:2353次出处信息

我们在做服务器的时候，老大扔给你一台机器，要你在上面开发。通常服务器软件是非常依赖于系统的软硬件的，软件通常是要紧贴硬件的特性，如果我们不能了解机器的硬件，我们就无法高效的开发。

比如说想知道Linux的系统的版本，CPU有几个，内存多少大，机器什么型号，Raid卡什么型号，硬盘有几个，文件系统是什么样子的，网卡什么型号，文件句柄设置什么的，用到虚拟化技术了吗，网络配置什么样的，目前资源使用是如何?

当然如果你足够有经验的话，这些问题难不倒你，但是你获取完全的这些信息是很麻烦的。

这时候Percona 来救助了。他提供了一整套工具来协助定位MySQL服务器的问题。这套工具适合于大部分的IO服务器。

Aspersa is a collection of open-source system utilities primarily designed to ease the work of Percona consultants. This manual is the primary documentation for Aspersa tools. Please contribute your improvements.
