Linux Dash监控在PowerLinux平台上的安装和应用

浪潮商用机器，技术支持部，杨宇

客户在业务环境中，经常需要对所管理的Linux服务器进行性能监控，以准确评估当前服务器的性能表现。然而Linux原生的性能监控小工具通常都是字符界面，通过命令行来进行操作和启停，对于管理员的技能要求比较高，同时展现也不够直观。

一些开源的监控小工具能够很好地弥补这方面的不足。Linux Dash就是一款轻量级、低开销 Linux 服务器监控工具，基于 Web 的监控界面，能够对Linux服务器的处理器、内存、网络和磁盘当前的使用进行有效直观的监控。

下面我们就在PowerLinux平台上，看看如何安装和运用Linux Dash吧：

• 1、 安装git版本控制工具，并确认安装的版本信息。

[root@yytest home]# yum -y install git

• 3，我们可以看到目录下多了linux-dash目录。

[root@yytest home]# ll

• 4，进入/linux-dash/app/server目录下，我们可以看到Linux Dash支持四种不同的server执行脚本。

Node.js
Go
Python
PHP

[root@yytest server]# pwd

/home/linux-dash/app/server

[root@yytest server]# ll

• 5，本次我们选择用Python来运行，先安装Python。（本人实测Go语言执行也OK）。

[root@yytest server]# yum install -y python
