nagios 监控 内存

前提：把check_mem.sh放到/usr/local/nagios/libexec下，并赋予执行权限

chmod 755 check_mem.sh

 

一，监控本地（监控端本身）内存使用：

#修改commands配置

vim /usr/local/nagios/etc/objects/commands.cfg
#增加以下内容
define command{
                command_name        check_mem
                command_line        $USER1$/check_mem.sh -w $ARG1$ -c $ARG2$
                }

#修改localhost.cfg

vim /usr/local/nagios/etc/objects/localhost.cfg
#增加以下内容
define service{
                use                                                         local-service
                host_name                                             localhost
                service_description                         memory
                check_command                                     check_mem!20!10!
                }

 

二，监控客户端内存使用情况：

  1,#修改客户端配置文件
    vim /usr/local/nagios/etc/nrpe.cfg

        #增加以下内容    
    command[check_mem]=/usr/local/nagios/libexec/check_mem.sh -w 20 -c 10
            
  2,#修改主控制端相关配置文件
     vim /usr/local/nagios/etc/service/liguxk.cfg    #主控端定义的被控端的配置文件
     #增加以下内容
                  define service{
                  use                                                         generic-service
                  host_name                                             liguxk
                  service_description                         Memory
                  check_command                                     check_nrpe!check_mem
                  }

 

三，总结

 

监控本地资源的调用流程为：

localhost.cfg―>command.cfg―>libexec

监控客户端流程：

liguxk.cfg―>服务器nrpe――>客户端nrpe.cfg―>客户端libexec
