1、环境说明
由于最近zabbix进行过一次迁移，所以zabbix-server系列采用docker方式安装，参考zabbix官网：https://github.com/zabbix/zabbix-docker。为适应本地环境和需求，docker-compose.yml文件有改动，具体内容如下：
docker-compose.yml文件

2、zabbix添加自定义监控
（1）zabbix_server.conf配置
#脚本路径
AlertScriptsPath=/usr/lib/zabbix/alertscripts
ExternalScripts=/usr/lib/zabbix/externalscripts
（2）zabbix_agent.conf配置
##允许使用用户自定义参数
UnsafeUserParameters=1
##导入该文件下的配置
Include=/etc/zabbix/zabbix_agentd.d/*.conf
（3）自定义监控脚本
/usr/lib/zabbix/externalscripts/docker_discovery.py，搜集正在运行的容器的名称
复制代码
#!/usr/bin/env python
# -*- coding: utf-8 -*
import os
import simplejson as json
t=os.popen("""docker ps |grep -v 'CONTAINER ID'|awk {'print $NF'} """)
container_name = []
for container in t.readlines():
r = os.path.basename(container.strip())
container_name += [{'
