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
