2.2.3_zabbix监控端口并发数
监控端添加脚本：
vim /usr/local/zabbix/tcp_connection_status.sh
#!/bin/bash
#this script is used to get tcp and udp connetion status
#tcp status
metric=$1
tmp_file=/tmp/tcp_status.txt
/bin/netstat -an|grep 8081|awk '/^tcp/{++S[$NF]}END{for(a in S) print a,S[a]}' > $tmp_file
case $metric in

添加zabbix的web端获取参数：
vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/tcp_status.conf
UserParameter=tcp.status[*],sh /usr/local/zabbix/tcp_connection_status.sh $1
测试：zabbix_get -s 172.23.9.162 -p 10050 -k tcp.status[timewait]
zabbix的web页面配置：
zabbix在取到的值很大时会自动变成K，M，G
修改自定义单位，不会自动转换，修改方法：
vim /usr/local/nginx/html/zabbix/include/func.inc.php
将：$blackList = ['%', 'ms', 'rpm', 'RPM'];
修改为：$blackList = ['%', 'ms', 'rpm', 'RPM','citem'];
