1. 在交换机上启用snmp并配置团体名(交换换机IP192.168.5.209)

   Switch(config)#snmp-server community public ro

   Switch(config)#snmp-server community public rw

2.在nagios服务器上输入如下命令获取交换机的index信息

[root@localhost ~]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C public  -H 192.168.5.209  -L

List Interface for host 192.168.5.209.

Interface index 1 orresponding to  Vlan1

Interface index 10001 orresponding to  FastEthernet0/1

Interface index 10002 orresponding to  FastEthernet0/2

Interface index 10003 orresponding to  FastEthernet0/3

Interface index 10004 orresponding to  FastEthernet0/4

Interface index 10005 orresponding to  FastEthernet0/5

Interface index 10006 orresponding to  FastEthernet0/6

Interface index 10007 orresponding to  FastEthernet0/7

Interface index 10008 orresponding to  FastEthernet0/8

Interface index 10009 orresponding to  FastEthernet0/9

Interface index 10010 orresponding to  FastEthernet0/10

Interface index 10011 orresponding to  FastEthernet0/11

Interface index 10012 orresponding to  FastEthernet0/12

Interface index 10013 orresponding to  FastEthernet0/13

Interface index 10014 orresponding to  FastEthernet0/14

Interface index 10015 orresponding to  FastEthernet0/15

Interface index 10016 orresponding to  FastEthernet0/16

Interface index 10017 orresponding to  FastEthernet0/17

Interface index 10018 orresponding to  FastEthernet0/18

Interface index 10019 orresponding to  FastEthernet0/19

Interface index 10020 orresponding to  FastEthernet0/20

Interface index 10021 orresponding to  FastEthernet0/21

Interface index 10022 orresponding to  FastEthernet0/22

Interface index 10023 orresponding to  FastEthernet0/23

Interface index 10024 orresponding to  FastEthernet0/24

Interface index 10101 orresponding to  GigabitEthernet0/1

Interface index 10102 orresponding to  GigabitEthernet0/2

Interface index 10501 orresponding to  Null0

3.在nagios服务器上输入如下命令获取交换机的F0/1的流量信息

[root@localhost ~]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C public -H 192.168.5.209 -I 10001 -w 200,300 -c 400,500 -K -B

OK - It‘s the first time for this plugins run. We‘ll get the data from the next time.

#第一次提示OK...，30秒后再次输入此命令

[root@localhost ~]# /usr/local/nagios/libexec/check_traffic.sh -V 2c -C public -H 192.168.5.209 -I 10001 -w 200,300 -c 400,500 -K -B

OK - The Traffic In is 1.00KB, Out is 0.62KB, Total is 1.62KB. The Check Interval is 46s |In=1.00KB;200;400;0;0 Out=0.62KB;300;500;0;0 Total=1.62KB;500;900;0;0 Interval=46s;1200;1800;0;0

4.在commands.cfg 中添加check_traffic命令(在监控windows流量中已添加)

5.修改nagios.cfg, 

44 去掉 cfg_file=/usr/local/nagios/etc/objects/switch.cfg 的#号

6.修改switch.cfg,定义switch主机名和监控服务

[root@localhost ~]# vim /usr/local/nagios/etc/objects/switch.cfg

25 使用generic-switch，此模板已存在templates.cfg中定义

26 主机名 使用了默认的 ，可以自定义

28 交换机的IP

104 services-pnp，使用画图，装有pnp才有效果

105 要监控的主机名 links-srw224p,已在26行定义

106 服务描述    名称自定义

107 检查命令  check_traffic 已在commands.cfg中定义 10001 是交换机f0/1的index值 200 400 是

    进/出流量（单位KB）超过这个值会发出警告，500 800  是进/出流量超过这个值会发出报警（根据实际情况设置这些流量值）

7.测试修改内容是否有错误，并重启nagios进程

[root@localhost ~]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

[root@localhost ~]# ps -ef | grep nagios

[root@localhost ~]# kill 16416

[root@localhost ~]# /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

8.访问nagios监控页面

提示/var/tmp有个临时文件，把/var/tmp/  下的临时文件全部删除

[root@localhost ~]# cd /var/tmp/

[root@localhost tmp]# rm -f *

再杀掉进程，启动进程,刷新监控页面
