如何查看系统当前主动、被动ESTABLISH？？

各位，今天领导要求ZABBIX里添加查看系统当前TCP主动、被动ESTABLISH数量的监控。
我想向各位求教一下，如何实现查看Network -TCP_ESTABLISHED incoming 和 Network -TCP_ESTABLISHED outgoing 和 Network TCP errors / sec (sum of resets, timeouts, retrans, etc.)这三个数据。
用命令netstat -s可以查看出以下信息，但这应该是总连接数，而不是当前ESTABLISED状态的INCOMING和OUTGOING数量：
Tcp:
1731 active connections openings
34686 passive connection openings
198 failed connection attempts
781 connection resets received
1 connections established 3907452 segments received
6783138 segments send out
47072 segments retransmited
0 bad segments received.
7636 resets sent
多谢了！
