nagios 监控流量插件check_traffic

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 bc

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

然后更改所属 chown nagios:nagios check_traffic.sh
执行如下命令查看网卡 /usr/local/nagios/libexec/check_traffic.sh -V 2c -C nagios -H localhost -L （which: no bc in (/program/system/jdk1.6/bin::/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin) Can not found command bc in you system PATH: /program/system/jdk1.6/bin::/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin, pleas check it *****解决办法 yum install bc ）


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
