一、Zabbix环境描述
1. 服务器系统及版本
CentOS Linux release 7.3.1611 (Core)
2. Zabbix版本
zabbix版本：3.4
mysql 5.7
3. Python版本
python 2.7（系统自带）
二、修改配置文件&编写Python脚本
1. 修改zabbix agent的配置文件
vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
# 本次添加的内容
UserParameter=port.discovery,/etc/zabbix/tools/port.py
2. 编辑Python脚本，并上传至/etc/zabbix/tools/
自动发现&监控大于1024的端口，具体可以通过修改代码自行修改~
#!/usr/bin/python
import os
import json
import sys
def discover():
d = {}
d['data'] = []
with os.popen("netstat -tnlp | awk {'print $4'}|awk -F':' '{if ($NF~/^[0-9]*$/) print $NF}' | awk '{if ($1 > 1024) print $1}'|sort|uniq") as pipe:
for line in pipe:
info = {}
info["{#TCPPORT}"] = line.replace("\n", "")
d["data"].append(info)
print json.dumps(d)
if __name__ == "__main__":
discover()
3. Zabbix Web导入模板
-
选择《配置》《模板》《导入》
-
选择模板文件
-
模板内容如下：

- 关联主机
自行添加咯
