一,安装所需软件net-snmp net-snmp-utils net-snmp-libs net-snmp-devel

yum install net-snmp net-snmp-utils net-snmp-libs net-snmp-devel

二,修复snmp配置:

vim /etc/snmp/snmp.conf 修改为:

# sec.name source community

#com2sec notConfigUser default public

com2sec notConfigUser localhost public

access notConfigGroup "" any noauth exact mib2 none none

view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc

三,启动snmp服务:

service snmpd start

四,设置开启启动:

chkconfig snmpd on

五,上传插件到/usr/local/nagios/libexec (插件在附件中)

六,配置

测试check_traffic 脚本:

cd /usr/local/nagios/libexec

./check_traffic -V 2c -C nagios -H localhost –L命令列出网络接口

cd /usr/local/nagios/etc

vim nrpe.cfg #添加

command[check_traffic]=/usr/local/nagios/libexec/check_traffic -V 2c -C public -H localhost -I 2 -w 2200,4000 -c 2500,4500 -K -B

-I 2 指网卡接口(就是你要监控的网卡接口)

修改chown nagios:nagios /var/tmp/check_traffic_localhost_2.hist_dat

重启nrpe 服务

七,配置监控服务器:

cd /usr/local/nagios/etc/objects

编辑vim services.cfg中添加:

define service {
use services-pnp
host_name xxx-Server
service_description check-traffic
check_period 24x7
max_check_attempts 4
normal_check_interval 3
retry_check_interval 2
contact_groups sagroup
notification_interval 10
notification_period 24x7
notification_options w,u,c,r
check_command check_nrpe!check_traffic
}

八,测试
