zabbix 配置文件：

UserParameter=ib_network.get[*],/usr/bin/python3 /etc/zabbix/externalscripts/ib_network_discovery.py  net_traffic_total $1
UserParameter=ib_network.rx[*],cat /etc/zabbix/externalscripts/$1 | head -n 1
UserParameter=ib_network.tx[*],cat /etc/zabbix/externalscripts/$1 | tail -n 1

添加自动发现模板：

添加监控项原型

获取数值监控项，此值没有值，只是希望可以获取到后面两项监控项

rx 和 tx 值

‍

最后看图形

shell 脚本自动发现 IB 网卡名称

#!/bin/bash
IBS=(`ifconfig -a | grep -o 'ib\w*'`)
LENGTH=${#IBS[*]}

printf "{\n"
printf  '\t'"\"data\":["
for ((i=0;i<$LENGTH;i++))
do
        printf '\n\t\t{'
        printf "\"{#IB_NAME}\":\"${IBS[$i]}\"}"
        if [ $i -lt $[$LENGTH-1] ];then
                printf ','
        fi
done
printf  "\n\t]\n"
printf "}\n"
