学向勤中得，萤窗万卷书。这篇文章主要讲述zabbix-监控tcp连接相关的知识，希望能为你提供帮助。
【zabbix-监控tcp连接】主动模式测试：
主动模式参考：??https://blog.51cto.com/u_14814545/4869452??
获取监控值脚本【192.168.47.105】

root@ubuntu:/etc/zabbix/zabbix_agentd.d# pwd
/etc/zabbix/zabbix_agentd.d

vim tcp_conn.sh
-------------------------------------------------------------------------------------
tcp_conn_status()
TCP_STAT=$1
ss -ant | awk NR> 1 ++s[$1] END for(k in s) print k,s[k] > /tmp/tcp_conn.txt
TCP_NUM=$(grep "$TCP_STAT" /tmp/tcp_conn.txt | cut -d-f2)
if [ -z $TCP_NUM ]; then
TCP_NUM=0
fi
echo $TCP_NUM

main()
case $1 in
tcp_status)
tcp_conn_status $2;
; ;
esac

main $1 $2
-------------------------------------------------------------------------------------

chmod a+x tcp_conn.sh.sh

修改配置文件【192.168.47.105】
vim /etc/zabbix/zabbix_agentd.conf
------------------------------------------------------------------------------
UserParameter=linux_status[*],/etc/zabbix/zabbix_agentd.d/tcp_conn.sh $1 $2
------------------------------------------------------------------------------

systemctl restart zabbix-agent

测试【192.168.47.104】
/apps/zabbix_agent/bin/zabbix_get -s 192.168.47.105 -p 10050 -k "linux_status[tcp_status,LISTEN]"
