本文介绍如何使用Python3调用wxpy模块，实现对Linux系统日志的实时监控，并通过定时任务将监控结果（如Kafka消费延迟信息）以文字或图片形式发送给微信好友或群组。文章提供了完整的代码示例，包括登录缓存、子进程调用及定时调度器的配置方法。

Python3结合wxpy实现Linux日志监控与微信定时通知

通过Python3调用wxpy模块，可以实现对Linux系统日志的自动监控，并设定定时任务将监控消息推送至指定的微信群组或好友。具体实现方案及代码细节如下所示：


#!/usr/bin/env python3
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from threading import Timer
from wxpy import *
import requests
import subprocess
import time
from PIL import Image, ImageDraw, ImageFont
from apscheduler.schedulers.blocking import BlockingScheduler
#cache_path=true 表示登陆一次之后，进行缓存，下次登陆只需要手机确认
bot = Bot(console_qr=2,cache_path=True)
#获取topic是否消费延迟
def get_Lag():
  text=""
  p = subprocess.Popen('kafka-consumer-offset-checker --zookeeper 192.168.1.116 --group t_sync --topic SYNC_DATABASE_UPDATE', shell=True, stdout=subprocess.PIPE,stderr=subprocess.PIPE,universal_newlines=True) #universal_newlines=True，表示输出为字符串，默认是byte
  while True:
    line =p.stdout.readline()
    if not line:
      break
    else:
      text+=line + '\n'
  return text
def get_news():
  text=[]
  count=0
  t=True
  p = subprocess.Popen('tail -F /home/hadoop/da.txt', shell=True, stdout=subprocess.PIPE,stderr=subprocess.PIPE,universal_newlines=True)
  while True:
    line =str(p.stdout.readline())
    if not line:
      break
    elif "send data" in line and t:
      for item in line.split(','):
        count +=1
        if count <= 200:
           text.append(item)
      break
  return text
def get_context():
  result=""
  word=get_news()
  for i in range(len(word)):
    if(i % 4 ==0):
      result= result+word[i]+"\n"
    else:
      result= result+word[i]+"  "
  return result
def send_image():
  try:
    lags=get_Lag()
    print(lags)
    content=get_context()
#发送消费延迟的数据
    lagImage= Image.new('RGB', (1000, 600),(255,255,255))
    draw = ImageDraw.Draw(lagImage)
    font = ImageFont.truetype("/usr/share/fonts/cjkuni-ukai/ukai.ttc", 18, encoding="unic")
    draw.text((10, 10), lags, 'black', font)
    lagImage.save('/home/hadoop/lags.jpg')
#发送日志消息
    image= Image.new('RGB', (1000, 810),(255,255,255))
    draw = ImageDraw.Draw(image)
    font = ImageFont.truetype("/usr/share/fonts/cjkuni-ukai/ukai.ttc", 18, encoding="unic") #ukai.ttc 字体
    draw.text((10, 10), content, 'black', font)
    image.save('/home/hadoop/123.jpg')
 
 #发送群组
    group = bot.groups().search("大数据小组")[0]
    group.send_image('/home/hadoop/123.jpg')
 #发送好友
    my_friend = bot.friends().search(u'涛')[0]
    my_friend.send_image('/home/hadoop/lags.jpg')
    my_friend.send_image('/home/hadoop/123.jpg')
    # t = Timer(100, send_image)
    #t.start()
  except:
    my_friend.send(u"今天消息发送失败了")
if __name__ == "__main__":
  #send_image()
  scheduler = BlockingScheduler()
  scheduler.add_job(send_image, 'cron', hour='15', minute='01')
  scheduler.add_job(send_image, 'cron', hour='14', minute='58')
  scheduler.start()
