自动发现实现url+响应时间监控

url自动发现脚本：

[root@jenkins scripts]# cat  urlDiscovery.py

#!/usr/bin/env python
#coding:utf-8

import os
import sys
import json

#这个函数主要是构造出一个特定格式的字典，用于zabbix
def web_site_discovery():
    web_list=[]
    web_dict={"data":None}
    with open("/etc/zabbix/server_list","r") as f:
        for url in f:
            dict={}
            dict["{#SERVICENAME}"]=url.strip().split()[0]
            dict["{#SITENAME}"]=url.strip().split()[1]
            web_list.append(dict)

    web_dict["data"]=web_list
    jsonStr = json.dumps(web_dict, sort_keys=True, indent=4)
    return jsonStr

if __name__ == "__main__":
    print web_site_discovery() 

url响应时间监控脚本：

url监控列表：

[root@jenkins scripts]# cat /etc/zabbix/server_list
api https://www.xxxxx.de/rest/v1/tags
AWScdn https://d3m2x14ac3st9e.cloudfront.net

url访问会出现不稳定的情况，需要调整/etc/zabbix/zabbix_agentd.conf 的超时时间

Timeout=30

添加url监控配置文件

[root@jenkins zabbix_agentd.conf.d]# cat userparameter_url.conf
UserParameter=web_site_discovery,/usr/bin/python /etc/zabbix/scripts/urlDiscovery.py
UserParameter=url.info,/usr/bin/python /etc/zabbix/scripts/urlResponse.py >/dev/null 2>&1 && echo 0 || echo 1
