zabbix问题事件统计/按月统计/生成表格/Python调用Zabbix3.4api

背景：

    因业务需要，每月初需要为客户提供指定预警等级的事件，这里选择从evnet.get中进行获取。

 

发现的坑：

    目前维护多套zabbix服务,并且版本不同..， POC进行时使用的是5.4.2, 正式环境3.4.x， 3.4版本中的event.get是没有name属性的，

    最后我是通过trigger拿到的信息，但因为tigger中带着{HOST.NAME} 或 {HOST.CONN} 这块儿通过ip类的信息进行了正则替换，具体如代码，比较简单，主要是API使用思路。

 

目的：

    获取事件名称、开始时间、 主机名称和IP信息，整理后以表格展示

 

调取结构图 ：

 

代码环境：

    Python3.8

代码依赖包：

    pip install openpyxl

    pip install pandas

    pip install requests

 

代码： 

import requests
import json
import pandas as pd
import time
import re

def stamp2time(timestamp): #时间戳转日期函数
    time_local = time.localtime(int(timestamp))
    dt = time.strftime("%Y-%m-%d %H:%M:%S", time_local)

有待改进：

    - 各个参数的传递

    - 事件数量过多的话，整个统计过程会非常缓慢，需要进行多线程优化
