vbscript - 使用 NRPE 执行远程脚本

Question

如果在远程服务器上指定插件命令，则可以执行脚本。
在下面的示例中，插件命令是 get_disk:

 command[get_disk]=csript.exe c:\nagios\checks\check_disks_percentage_spave_used.vbs

不过，我希望远程服务器上的 NRPE 在客户端服务器上执行脚本，而无需插件命令。
在远程服务器上是这样的:

check_nrpe  -H 196.35.132.9 -t 60 -c 'csript.exe c:\\nagios\\checks\\check_disks_percentage_space_used.vbs'

Answer 1

您可以按照以下步骤从 nagios 运行命令以监控远程计算机

1. 假设您有 2 台机器，
2. 从你想监控的地方(将其称为 master)
3. 您想监视谁(将其称为奴隶)
4. 假设您在 linux 中工作，并且在主计算机 nagios 中的位置是“/usr/local/nagios”
5. 你的slave机器也是linux，nrpe安装位置是"/usr/local/nagios"

6. 将您的脚本/插件/可执行文件放在从机的@/usr/local/nagios/libexec 位置。

   e.g. - /usr/local/nagios/libexec/test.sh
   and give it executable permission.
   chmod +x test.sh

   1. 编辑 nrpe.cfg 并在其中添加命令

   
   vi /usr/local/nagios/etc/nrpe.cfg
   add following line
   command[testScript]=/usr/local/nagios/libexec/test.sh
   telling nrpe to run test.sh when it receives testScript command

8.重启nrpe
9. 转到主机
10.编辑commands.cfg

vi /usr/local/nagios/etc/objects/commands.cfg
and add following line

define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
by adding this, now master machine is aware what is check_nrpe command.

1. 添加服务

   define service{
   use generic-service
   host_name web-node01
   service_description count number of cmd in remote mc
   check_command check_nrpe!testScript
   }
   now nagios know that it has to call testScript command in slave machine,
   and in slave machine we have defined when received testScript command run 'test.sh'
   from thi s'/usr/local/nagios/libexec' location (point no. 7)

2. 现在，在从 nagios 尝试之前，您可以直接调用 nrpe 命令，按照以下命令检查是否一切正常

   /usr/local/nagios/libexec/check_nrpe -H slave_IP_Address -c testScript
   P.S. this is exactly same command that nagios will run behind the scene
