使用python获取交换机syslog日志并使用jQuery在html上展示

需求

　　现网有部分pop点独立于海外，无法发送日志给内网日志服务器，同时最近网内有比较重要割接，所以临时写一个脚本来展示网内日志

思路

　　使用socket接收syslog数据，udp 514，数据部分格式化后写入js文档，html调用js文档来实现日志可视化

效果

python代码

import socket,re,os

def syslog(date):

    date = date.replace('\"','\'')

    pri = re.findall('\d+',date)[0]

    pri = int(pri)

    level = re.findall('<\d+>',date)[0]

    div_class = 'debug'

    if pri%8 == 0:

        date = date.replace(level,'emerg ')

        div_class = 'error'

    elif pri%8 == 1:

        date = date.replace(level,'alert ')

        div_class = 'error'

    elif pri%8 == 2:

        date = date.replace(level,'crit ')

        div_class = 'error'

    elif pri%8 == 3:

        date = date.replace(level,'error ')

        div_class = 'error'

    elif pri%8 == 4:

        date = date.replace(level,'warning ')

        div_class = 'warning'

    elif pri%8 == 5:

        date = date.replace(level,'notice ')

    elif pri%8 == 6:

        date = date.replace(level,'info ')

    elif pri%8 == 7:

        date = date.replace(level,'debug ')

    return date,div_class

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

address = ('172.16.0.33',514)

s.bind(address)

while True:

    date,address = s.recvfrom(10240)

    date = date.decode(encoding='utf8')

    date,div_class = syslog(date)

    print(date)

    with open ('/var/www/html/log.js','a') as f:

        f.write(''' \n$('#log').prepend("<div class = '%s'>%s</div>")'''%(div_class,date.rstrip()))
