zabbix_agent自动发现服务端口

Posted 2022-02-02 jianghanyang

应用背景:

      zabbix监控系统介绍及安装，参考大牛运维生存时间，在这儿就不啰嗦了

为了zabbix-agent端能自动把服务器端的服务端口汇报给 zabbix server端，监控其端口是否存活可用，

用下面的脚本：service_scan.py   部署于agent端 /usr/local/zabbix-agent/bin/service_scan.py

部署准备:

1. service_scan.py脚本 依懒 python2.7版本下的 psutil库，
2. 需要在agent端安装 python2.7版本，
3. 用python2.7 安装相关的 psutil库

1	/usr/local/python27/bin/pip install psutil
