提取Zabbix监控平台单台服务器图形并发邮件Python实现

需求:希望每天邮件发出当天某台服务器的监控状态,如果某天都登陆zabbix截图很麻烦,而且并不能保证每天都准点操作,于是写了一段脚本实现自动抓取图片,并组装成html,通过定时邮件发送,实现日报自动化。

    ZabbixG=ZabbixGraph(indexURL,username,password)
    ZabbixG.GetGraph(gr_url,values,image_dir)
    ZabbixG.SendMail(receiver,Subject,smtpserver,mail_username,mail_password,values,image_dir,HostName,GraphsName)

通过以上获取的图片,在组装html,然后使用系统计划任务可实现自动化日报发送。
