豆子平常一般习惯用Nagios监控系统的状态。平常公司使用VEEAM来管理文件的备份和还原，备份的结果一般通过Email发送给豆子。今天心血来潮，想把这个备份的状态在Nagios的监控界面上也展现出来。
因为VEEAM本身提供了PowerShell的模块，因此豆子可以通过NSclient++客户端来调用自定义的PowerShell脚本，从而实现监控的目的。
1） 自定义的 Powershell脚本 veeam_backup.ps1, 脚本很简单，根据不同的结果返回不同的exit的值。
Nagios里面的定义是
-
0- OK
-
1- Warning
-
2- Critial
-
3- Unknow

2） 第二步需要修改我们的Nsclient++的配置文件 nsclient.ini 这个地方一定要确保格式正确 不然nagios无法识别我们自己写的外部命令。
nisclient.ini 配置文件关键配置如下

修改完毕，重启nscp服务之后，在SSH登录Nagios服务器，测试该命令是否能够识别

[root@sydnagios libexec]

3） 配置Nagios的command.cfg, host.cfg和service.cfg

4）测试
重启Nagios服务，然后在页面即可看见结果。
结果和VEEAM 管理界面一致
