创建执行脚本：

# cat /etc/zabbix/monitor_scripts/network.sh
#!/bin/bash
#set -x
usage() {
echo "Useage : $0"
echo "eg. sh $0 eth0"
exit 1
}
if [ $# -lt 1 ]
then
usage
fi
eth=$1
timer=1
in_old=$(cat /proc/net/dev | grep $eth | sed -e "s/$.*$\:$.*$/\2/g" | awk '{print $1 }')
out_old=$(cat /proc/net/dev | grep $eth | sed -e "s/$.*$\:$.*$/\2/g" | awk '{print $9 }')
x=1
while [ $x -le 2 ]
do
sleep ${timer}
in=$(cat /proc/net/dev | grep $eth | sed -e "s/$.*$\:$.*$/\2/g" | awk '{print $1 }')
out=$(cat /proc/net/dev | grep $eth | sed -e "s/$.*$\:$.*$/\2/g" | awk '{print $9 }')
dif_in=$(((in-in_old)/timer))
dif_in=$((dif_in/1024))
dif_out=$(((out-out_old)/timer))
dif_out=$((dif_out/1024))
ct=$(date +"%F %H:%M:%S")
echo "${ct} -- IN: ${dif_in} KByte/s OUT: ${dif_out} KByte/s"
in_old=${in}
out_old=${out}
x=3
done
exit 0

# cat /etc/zabbix/monitor_scripts/networkin.sh
/etc/zabbix/monitor_scripts/network.sh eth1 |awk '{print $5}'# cat /etc/zabbix/monitor_scripts/networkout.sh
/etc/zabbix/monitor_scripts/network.sh eth1 |awk '{print $8}'

修改配置文件，关联自定义key:

]# grep Include /etc/zabbix/zabbix_agentd.conf
### Option: Include
# Include=
# Include=/etc/zabbix/zabbix_agentd.userparams.conf
# Include=/etc/zabbix/zabbix_agentd/
#Include=/etc/zabbix/zabbix_agentd/*.conf
Include=/etc/zabbix/zabbix_agentd.d/# cat /etc/zabbix/zabbix_agentd.d/networkInOut.conf
UserParameter=networkin,/etc/zabbix/monitor_scripts/networkin.sh
UserParameter=networkout,/etc/zabbix/monitor_scripts/networkout.sh

增加自定义模版：Network incoming or outcoming on eth1
