nagios监控国外主机超时

项目上在国外(新加坡)有个主机，由于和谐墙的原因，用check\_ping对其进行监控频繁超时，报错，收了一大堆通知邮件。没办法只能把检测超时时间设置大一点。

**1.编辑新的检测命令**

> vim /etc/nagios/objects/commands.cfg  \#增加如下内容-p 1 -t 200，意思是发送一个包，超时时间设置为200s  
>

> \# 'check-mwa-alive' command definition  
> define command\{  
>         command\_name    check-mwa-alive  
>         command\_line    $USER1$/check\_ping -H $HOSTADDRESS$ -w 3000.0,90% -c 5000.0,100% -p 1 -t 200  
>         \}

**2.增加检测主机是否存活模板**

> vim /etc/nagios/objects/templates.cfg  
> 
> 
> define host\{  
>         **name                            mwa-server    ; The name of this host template**  
>         use                             generic-host    ; This template inherits other values from the generic-host template  
>         check\_period                    24x7            ; By default, Linux hosts are checked round the clock  
>         **check\_interval                  30               ; Actively check the host every 30 minutes ;每隔30分钟检查一次  
>         retry\_interval                  1               ; Schedule host check retries at 1 minute intervals ;重试间隔  
>         max\_check\_attempts              5               ; Check each Linux host 10 times (max);重试次数  
>         check\_command                   check-mwa-alive ; Default command to check Linux hosts;检测命令，第一步定义的**  
> \#       notification\_period             workhours       ; Linux admins hate to be woken up, so we only notify during the day  
>                                                         ; Note that the notification\_period variable is being overridden from  
>         notification\_period             24x7            ; the value that is inherited from the generic-host template!  
>         notification\_interval           60              ; Resend notifications every 2 hours  
>         notification\_options            d,u,r           ; Only send notifications for specific host states  
>         contact\_groups                  users           ; Notifications get sent to the admins by default  
>         register                        0               ; DONT REGISTER THIS DEFINITION - ITS NOT A REAL HOST, JUST A TEMPLATE!  
>         \}  
>

**3.编辑检测项目**

> vim /etc/nagios/server/mwa.cfg
> 
> define host\{  
>         **use                     mwa-server **           ; Name of host template to use ;用第二部定义的模板：**mwa-server**  
>         host\_name               mwa  
>         alias                   mwa  
>         address                 128.199.93.212  
>         \}

**4.检查配置文件是否正确**

> nagios -v /etc/nagios/nagios.cfg
> 
> 。
> 
> 。
> 
> 。
> 
> Checking services...  
>     Checked 54 services.

**5.重启nagios服务**

> service nagios restart
