我在 Nagios / NRPE 服务方面遇到问题，如下所示：

我已经完成了每个文件的配置，但无法识别我 NRPE 在客户端传递的 nagios 响应：

文件：/etc/nagios/nrpe.cfg（客户端）

command[check_users]=/usr/lib64/nagios/plugins/check_users -w 5 -c 10
command[check_load]=/usr/lib64/nagios/plugins/check_load -w 15,10,5 -c 30,25,20
command[check_disk]=/usr/lib64/nagios/plugins/check_disk -w 20% -c 10% -p /dev/mapper/VG_opt-LV_opt
command[check_zombie_procs]=/usr/lib64/nagios/plugins/check_procs -w 5 -c 10 -s Z
command[check_total_procs]=/usr/lib64/nagios/plugins/check_procs -w 150 -c 200

文件：services.cfg（服务器）

define service{
  use                   generic-service
  host_name             192.168.160.10, 192.168.160.11, 192.168.160.12
  service_description   Disk Space
  notification_options w,u,c,r
  check_command         check_nrpe!check_disk
}

很明显，我重启了客户端和服务器上的服务，通过NRPE进行了其他协商，得到了结果，因为进程数、CPU和RAM是check_disk的问题。

在本地用 check_disk 得到的结果是：

DISK OK - free space: /opt 34024 MB (76% inode=98%);| /opt=10522MB;37544;42237;0;46930

结果通过网络

Disk SpaceUNKNOWN    2014-09-26 09:18:31    0d 15h 52m 53s    4/4    (No output returned from plugin)

如果我从nagios 服务器得到结果，那就更奇怪了。

$ ./check_nrpe -H 192.168.160.10 -c check_disk
DISK OK - free space: /opt 33389 MB (74% inode=98%);| /opt=11156MB;37544;42237;0;46930

通过网络：

the last option supplied on the command line.
\nNote:
This plugin requires that you have the NRPE daemon running on the remote host.
You must also have configured the daemon to associate a specific plugin command
with the [command] option you are specifying here. Upon receipt of the
[command] argument, the NRPE daemon will run the appropriate plugin command and
send the plugin output and return code back to *this* plugin. This allows you
to execute plugins on remote hosts and 'fake' the results to make Nagios think
the plugin is being run locally.

这可能早就应该了，但我不得不做出回应。

@AlainCollins 评论道：

.. check_nrpe 命令是如何定义的？

define command{
  command_name    check_nrpe
  command_line    /usr/lib64/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$
}

以上是基本的 check_nrpe 命令。您在这里遇到的问题是您正在尝试从nrpe.cfg运行不需要参数的已定义命令。当您定义命令时，上面 NRPE 命令定义中的$ARG2$是“-a”获取其值的地方。因此，如果您将第一个参数“-c”作为命令check_disk提供，则它不会获得 $ARG2$ 的值。

要解决这个问题，您有 2 个选项：

1）在命令参数后的磁盘空间检查命令定义中添加一个占位符“ ！ ” ：

define service{
  use                   generic-service
  host_name             192.168.160.10, 192.168.160.11, 192.168.160.12
  service_description   Disk Space
  notification_options w,u,c,r
  check_command         check_nrpe!check_disk!
}

2) 使用/etc/nagios-plugins/config/check_nrpe.cfg中提供的“check_nrpe_1arg”命令- 该命令是为不需要参数的插件设计的，可以像常规 check_nrpe 一样使用：

define command{ 
  command_name check_nrpe_1arg
  command_line /usr/lib64/nagios/plugins/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
