nagios 监控交换机端口

1.下载监控插件

wget http://nagios-snmp.cvs.sourceforge.net/nagios-snmp/plugins/check_snmp_int.pl

2. 首先查看交换机目前开启的所有端口

for i in `seq 1 48`;do /usr/local/nagios/libexec/check_snmp_int.pl -H 192.168.0.254  -C public -n "^GigabitEthernet1/0/$i$";done

3. 添加监控

define host {

                use     generic-switch

                host_name       3750M-port

                alias           3750M-port

                address         192.168.0.254

}

define host {
