前面我们写了nagios的server端和client端的安装过程，这里我们写一下nagios的监控范例

添加监控本地服务器磁盘，监控/dev/sda3，即/分区

[root@nagios-server ~]# df -hFilesystem            Size  Used Avail Use% Mounted on/dev/sda3              97G  1.6G   90G   2% /tmpfs                 495M     0  495M   0% /dev/shm/dev/sda1             194M   28M  156M  16% /boot#编辑相应配置文件[root@nagios-server ~]# vim /usr/local/nagios/etc/objects/commands.cfg #从这个文件中我们知道该监控脚本需要3个参数define command{        command_name    check_local_disk        command_line    $USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$        }#修改文件，添加要监控的分区[root@nagios-server ~]# vim /usr/local/nagios/etc/objects/localhost.cfg define service{        use                             local-service        host_name                       localhost        service_description             disk_monitor        check_command                   check_local_disk!30%!20!/dev/sda3        notifications_enabled           1        }#用命令进行调试[root@nagios-server ~]# /usr/local/nagios/libexec/check_disk -w 30% -c 20% /dev/sda3DISK OK - free space: / 92072 MB (98% inode=99%);| /=1544MB;69038;78900;0;98626#检查配置文件[root@nagios-server ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg #重启nagios服务[root@nagios-server ~]# service nagios restartRunning configuration check...done.Stopping nagios: done.Starting nagios: done.

这里我们监控我们前一篇文章中的nagios-client:192.168.3.72的sdb

#编辑文件[root@nagios-client ~]# vim /usr/local/nagios/etc/nrpe.cfgcommand[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20command[check_sda3]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda3#添加sdb这一行command[check_sdb]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sdbcommand[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Zcommand[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200 #重启nrped服务[root@nagios-client ~]# service nrped restartStopping NRPE daemon... done.Starting NRPE daemon... done.[root@nagios-client ~]# netstat -anpt |grep nrpetcp        0      0 192.168.3.72:5666           0.0.0.0:*                   LISTEN      1492/nrpe

    在nagios-server:192.168.3.71进行配置

[root@nagios-server objects]# pwd/usr/local/nagios/etc/objects[root@nagios-server objects]# vim commands.cfg#在末尾添加如下内容define command{        command_name check_nrpe        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$        }[root@nagios-server etc]# pwd/usr/local/nagios/etc[root@nagios-server etc]# vim nagios.cfg#在第36行添加cfg_file=/usr/local/nagios/etc/objects/192.168.3.72.cfg[root@nagios-server objects]# pwd/usr/local/nagios/etc/objects[root@nagios-server objects]# cat 192.168.3.72.cfg define host{	use			linux-server	host_name		192.168.3.72	alias			nagios-client	address			192.168.3.72	}define hostgroup{	hostgroup_name		clients	alias			linux-servers	members			192.168.3.72	}define service{	use			generic-service	host_name		192.168.3.72	service_description	check_disk_sdb	check_command		check_nrpe!check_sdb	notifications_enabled	1        }    define service{        use                     generic-service        host_name               192.168.3.72        service_description     check_disk_sda3        check_command           check_nrpe!check_sda3        notifications_enabled   1        }[root@nagios-server objects]# chown nagios.nagios 192.168.3.72.cfg #检查配置文件[root@nagios-server objects]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg #重启nagios服务[root@nagios-server objects]# service nagios restartRunning configuration check...done.Stopping nagios: done.Starting nagios: done.
