監測與Nagios的磁盤 - NRPE - Linux的

我有關於Nagios的/ NRPE服務的一個問題是：監測與Nagios的磁盤 - NRPE - Linux的

我已經做了每個文件的配置，但不承認我Nagios的響應交付通過在客戶端上NRPE：

文件：/etc/nagios/nrpe.cfg（客戶端）

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（Servidor）

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 
}

顯然我重新啓動了客戶端和服務器上的服務，並通過NRPE獲得了其他諮詢結果，因爲進程數量，CPU和RAM是check_disk的問題。

本地與check_disk得到的結果是：

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

通過web結果

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

它更怪的時候從的Nagios服務器，如果我得到的結果。

$ ./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

通過網絡：

[command] = The name of the command that the remote daemon should run 
[arglist] = Optional arguments that should be passed to the command. Multiple 
arguments should be separated by a space. If provided, this must be 
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.

這是一個延伸，但如何定義的check_nrpe命令？ – 2014-10-09 06:20:31

這可能是姍姍來遲，但我有手藝的響應。

@AlainCollins評論：

..how定義的check_nrpe命令？

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。你在這裏遇到的問題是你試圖運行nrpe.cfg定義的命令，不需要參數。當你定義一個命令時，上面的NRPE命令定義中的$ ARG2 $是'-a'正在獲取其值的地方。因此，如果您提供第一個參數'-c'作爲命令check_disk它不會獲得$ ARG2 $的值。

爲了解決這個問題，你有兩個選擇：

1）添加一個佔位符的命令參數後磁盤空間 check_command定義「！」：

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）使用在/etc/nagios-plugins/config/check_nrpe中提供的「check_nrpe_1arg」命令。CFG - 此命令是專爲那些需要沒有參數，可以使用相同的常規check_nrpe插件：

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