Nagios监控对于服务器运维来讲是非常好的工具，可以监控各种操作系统的服务器，windows，linux,aix等等，还可以对路由器和交换机，打印机等网络设备进行监控，再结合邮件，短信,MSN等报警方式为系统管理人员节省了许多巡检时间而且成效显著！在我的运维环境中，随着监控客户端的增多，报警的频率也随着提高，没日没夜的收短信，最终不得不把手机短信调成震动模式。在收到的报警短信中，大部分是windows客户端异常的短信，相对而言，在服务器领域linux系统比windows系统稳定可靠的多。于是想到取消集中报警的方式，将windows报警发送到windows sa的手机上，linux报警发到自己的手机上，也就是分组短信报警。下面就来介绍下配置过程！
一:编辑command.cfg文件，添加fetion发送短信命令
[root@localhost ~]# vi /usr/local/nagios/etc/objects/commands.cfg
define command{
command_name notify-service-by-linux
command_line /usr/local/fx/fetion --mobile=1383838438--pwd=123--to=1383838438--msg-utf8="主机：IP地址$HOSTADDRESS$，服务器描述： $HOSTALIAS$/$SERVICEDESC$ 目前状
态：$SERVICESTATE$ 信息摘要： $SERVICEOUTPUT$" --msg-type=1
}
define command{
command_name notify-service-by-windows
command_line /usr/local/fx/fetion --mobile=1383838438--pwd=123--to=1333333333--msg-utf8="主机：IP地址$HOSTADDRESS$，服务器描述： $HOSTALIAS$/$SERVICEDESC$ 目前状
态：$SERVICESTATE$ 信息摘要： $SERVICEOUTPUT$" --msg-type=1
}
define command{
command_name notify-host-by-sms
command_line /bin/echo null
}
二:编辑contacts.cfg文件，分别定义linux服务器的告警信息通过notify-service-by-linux发送，windows服务器的告警信息通过notify-service-by-windows，在本例中因为所有的服务器均禁止ping,所以所有的主机告警信息不发送！
[root@localhost ~]# grep -v '^#' /usr/local/nagios/etc/objects/contacts.cfg
define contact{
contact_name linux
use linux-contact
alias linux
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r,f,s
host_notification_options d,u,r,f,s
service_notification_commands notify-service-by-linux
host_notification_commands notify-host-by-sms
}
define contact{
contact_name windows
use windows-contact
alias windows
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r,f,s
host_notification_options d,u,r,f,s
service_notification_commands notify-service-by-windows
host_notification_commands notify-host-by-sms
}
define contactgroup{
contactgroup_name linux
alias linux
members linux
}
define contactgroup{
contactgroup_name windows
alias windows
members windows
}
三：编辑templates.cfg文件，在模板文件中分别定义linux服务器和windows服务器的各监控属性和通知类型(最重要的参数contact_groups)，最后用于监控客户端配置文件上
[root@localhost ~]# vi /usr/local/nagios/etc/objects/templates.cfg
define contact{
name linux-contact
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r,f,s
host_notification_options d,u,r,f,s
service_notification_commands notify-service-by-linux
host_notification_commands notify-host-by-sms
register 0
}
define contact{
name windows-contact
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r,f,s
host_notification_options d,u,r,f,s
service_notification_commands notify-service-by-windows
host_notification_commands notify-host-by-sms
register 0
}

}
