zabbix-agent python脚本侦听服务器异常登录，并告警

py脚本

import re,subprocess,time,datetime

#gpasswd -a zabbix adm
def ftime(a):
    a = a.replace('Jan','01')

    return a

        logtime = (re.findall('[A-Z,a-z]+\s+\d+\s\d+:\d+:\d+',ret，flags=re.M))
        count = len(host)
        for x in range(count-1,-1,-1):
                f_logtime = int(ftime(logtime[x].replace(':','').replace('  ','0').replace(' ','')))
                if host[x] not in list and now_time - f_logtime < 1000:
                    ip = host[x].replace('.','0')
                    return int(ip)
        return(int(0))
    except Exception as a:
        return a
if __name__  == "__main__":
    print(auth())

zabbix item配置与triggers配置略

效果如下
