Shell整理－方便的检测网卡流量脚本

有时就算你有网卡监控的工作如cacti nagios这些长时间的监控工具，但有时为了解决临时的瞬时的一些检测任务，就需要直接查看到网卡的流量，还可以变化成自己喜欢的格式，只要你愿意去改脚本。这个脚本的单位跟cacti展示的是一样的。

今天正巧碰上看到两个一样的SHELL脚本 一个是英文原版的 一个是加了中文注释的,把采集的信息用wiki的格式输出。 感觉这个脚本挺清楚的，可以把中间的一些东西抽出来加以利用。

Shell整理－服务器信息收集程序

前言：我们常常需要收集服务器的信息，硬件的来补充硬件表，服务器的流量、连接数来监控服务器状态等都需要收集，而且还会想把收集过来的信息通过邮件或者excel表显示出来，等等。计划写了个比较强的综合性的服务器收集程序，现在下面先展示的是一个硬件信息收集的程序
这个程序的特点：适应slackware和centos redhat系列的系统，还有需要安装dmidecode 这个可以统计到空闲的PCI槽 物理内存的数量和大小 还可以统计CPU的物理个数和类型等。最后可以结合转excel脚本转换成excel文件。最后就可以形成了一张表。

Shell整理–检查WEB是否正常脚本(附PHP脚本)

前言：自从我们的网站用了nginx+fastcgi后，出了不少的问题，尤其在那一段时间内。出现的问题头疼之一的就是502，nginx并没有死，但fastcgi却死掉了，所以单单查看80端口是不够的，

另外我们的系统都是集群的，某一个WEB出现问题也是不好发现的（在没有加监控之前），所以当时好几个同事都写了相同功能的程序，我对SHELL熟悉，写了shell脚本，有同事是写PHP的 利用curl写了PHP的程序，还有利用shell结合curl写的，而我觉得curl要必须安装才有，所以我写了一个wget 的 利用最基本的系统命令就可以完成。

附上小刘的PHP脚本，后来他还加入了gtalk的消息发送
