Ping Servers with PowerShell

来源：互联网发布：新手python推荐书籍编辑：程序博客网时间：2024/06/06 02:52

这里给大家分享一个在工作中写的小脚本，原理很简单。

在我的工作中时常有大批服务器需要操作管理，当你从线上拿下几台server做处理操作后，就需要时刻监视server的在线状态，下面我写了一个ping server list的脚本，该脚本支持添加loop、online、offline参数。最后还会显示ping server list所花费的时间。

参数说明：

[loop]循环运行ping脚本

[online]只显示ping通的server

[offline]只显示未ping通的server

[loop][online]以循环模式显示ping通的server

[loop][offline]以循环模式显示未ping通的server

具体说明随后会演示。

脚本的核心十分的简单，调用了WMI的ping状态来判断，最后结合参数配合调用。运行的时候输入保存的server list文本地址就可以批量ping server了。

运行界面如下（因为出于安全，我将机器名作了些涂抹）：

添加loop参数，开启循环ping主机，直到按下中断组合键CTRL+C才会停止

添加online参数后只会显示ping通的主机

添加offline参数则只显示ping不通的主机

另外也可以使用组合参数loop和offline，脚本将会循环ping server，并且只显示ping不通的主机，直到按下CTRL+C中断组合键停止
