一、监控swap分区

在被监控机/usr/local/nagios/etc/nrpe.cfg里添加

command[check_swap]=/usr/local/nagios/libexec/check_swap -w 20% -c 10%

监控机/usr/local/nagios/etc/objects/commands.cfg添加

define command{
        command_name    check_local_swap
        command_line    $USER1$/check_swap -w $ARG1$ -c $ARG2$
        }

/usr/local/nagios/etc/servers/252.cfg里添加

define service{
        use                             generic-service         
        host_name                       252
        service_description             Swap Usage
        check_command                   check_nrpe!check_swap
        }
重启nagios服务

 

二、监控load负载情况

 

监控机/usr/local/nagios/etc/objects/commands.cfg添加（忘了是不是默认有此配置。。。有就不要加了）

define command{
        command_name    check_local_load
        command_line    $USER1$/check_load -w $ARG1$ -c $ARG2$
        }

/usr/local/nagios/etc/servers/252.cfg里添加

define service{
        use                             generic-service         
        host_name                       252
        service_description             Current Load
        check_command                   check_nrpe!check_load
        }
重启nagios服务

 

三、监控磁盘使用情况

在被监控机/usr/local/nagios/etc/nrpe.cfg里添加

command[check_disk_root]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /

监控机/usr/local/nagios/etc/objects/commands.cfg添加

define command{
        command_name    check_local_disk
        command_line    $USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$
        }
/usr/local/nagios/etc/servers/252.cfg里添加

define service{
        use                             generic-service         

        host_name                       252
        service_description             Root Partition
        check_command                   check_nrpe!check_disk_root
        }
重启nagios服务

 

四、监控HTTP

监控机/usr/local/nagios/etc/servers/252.cfg添加
define service{
        use                             generic-service         
        host_name                       252
        service_description             HTTP
        check_command                   check_http
        notifications_enabled           0
        }

重启nagios服务

 

五、监控内存使用情况

由于LINUX使用内存的机制，监控内存没多大必要，还是记录下来

在被监控机/usr/local/nagios/etc/nrpe.cfg里添加

command[check_mem]=/usr/local/nagios/libexec/check_mem -w 150 -c 200

把check_mem(见附件)放到/usr/local/nagios/libexec/下，并赋予权限

chmod +x /usr/local/nagios/libexec/check_mem

chown nagios.nagios /usr/local/nagios/libexec/check_mem

监控端/usr/local/nagios/etc/objects/commands.cfg添加

define command{
        command_name    check_mem
        command_line    $USER1$/check_mem -w $ARG1$ -c $ARG2$
        }

/usr/local/nagios/etc/servers/252.cfg添加

define service{
        use                             generic-service         ; Name of service template to use
        host_name                       252
        service_description             memory
        check_command                   check_nrpe!check_mem!110,80!150,100
       }
