测试脚本是否可用
[root@monitor scripts]# chmod +x tcp_connections.sh
[root@monitor scripts]# ./tcp_connections.sh ESTABLISHED

编辑zabbix_agentd配置
[root@monitor scripts]# vim /usr/local/etc/zabbix_agentd.conf.d/monitor_tcp_connections.conf
UserParameter=tcp.time_wait,/usr/local/scripts/tcp_connections.sh TIME_WAIT
UserParameter=tcp.close_wait,/usr/local/scripts/tcp_connections.sh CLOSE_WAIT
UserParameter=tcp.fin_wait1,/usr/local/scripts/tcp_connections.sh FIN_WAIT1
UserParameter=tcp.established,/usr/local/scripts/tcp_connections.sh ESTABLISHED
UserParameter=tcp.syn_recv,/usr/local/scripts/tcp_connections.sh SYN_RECV
UserParameter=tcp.last_ack,/usr/local/scripts/tcp_connections.sh LAST_ACK
UserParameter=tcp.listen,/usr/local/scripts/tcp_connections.sh LISTEN
重启服务
[root@monitor scripts]# /etc/init.d/zabbix_agentd restart
Shutting down zabbix_agentd: [确定]
Starting zabbix_agentd: [确定]
测试监控是否有数据
[root@monitor scripts]# zabbix_get -s localhost -k tcp.established

然后在web里创建模版，方便以后多台添加
填写模版名称
创建监控项
创建图形
等一会儿数据图形就会出现
