Python实现云备份进程状态监控与自动报警脚本

本文提供了一个Python脚本示例，用于验证云备份进程是否处于正常运行状态。该脚本通过详细的代码实现，帮助开发者或运维人员参考学习，确保备份任务的可靠性。

监控场景与需求

应用场景设定为服务器自动备份数据库文件，系统每两小时生成一个新的备份文件，并由云备份客户端自动执行上传操作。运维人员需要每日检查备份是否成功完成。

脚本功能实现

脚本的主要功能包括：验证文件是否已成功备份，检查相关进程是否正在运行，并在检测到问题时发送相应的邮件通知。

#! /usr/bin/env python
import os
import time
import smtplib
from email.mime.text import MIMEText
from email.header import Header 
from configparser import ConfigParser 
def SendMail(server,sender,pwd,receiver,msg):
  '''
  Conncet to Office365 mail server and sent emails
   
  '''
  email = smtplib.SMTP(server,587)
  email.starttls()
  email.ehlo(server)
  email.login(sender,pwd)
  email.sendmail(sender,receiver,msg)
  email.quit()     
def GetNewFiles(path,num):
  '''
  Get file lists and return the last num created files   
  '''
  lists = os.listdir(path)
  lists.sort(key=lambda fn:os.path.getctime(path+'\\'+fn))   
  return lists[-num : ]   
def CheckProcess(name):
  '''
  Check if the process exits and return result.
   
  ['\n', 'Image Name           PID Session Name    Session#  Mem Usage\n', '========================= ======== ================ =========== ============\n', 'Dropbox.exe         20484 Console          1   71,652 K\n', 'Dropbox.exe         23232 Console          1   2,456 K\n', 'Dropbox.exe         61120 Console          1   2,168 K\n']

  proc = []
  p = os.popen('tasklist /FI "IMAGENAME eq %s"' % name)
  for x in p:
    proc.append(x)
  p.close()
  return proc
   
def MailContent(path,num):
  '''
  make the mail contents
  '''
  content = []
   
  dropbox = CheckProcess('dropbox.exe')
  carboniteservice = CheckProcess('carboniteservice.exe')
   
  #IF process doesn't run
  if len(dropbox) < 2 or len(carboniteservice) < 2 :
    content.append("Dropbox or CarBonite doesn't run")
    s = '\n\t'.join(dropbox) + '\n\n' + '\n\t'.join(carboniteservice)
    content.append("Process Check Result:\n\t" + s)
    return content
   
  #Check if the backup files are correct.
  files = GetNewFiles(path,num)
  file_ctime = os.path.getctime(path + '\\' + files[0])
  now = time.time() - 86400
   
  if file_ctime > now :
    content.append("DB Backup Successfull")
    body = "\nThe Backup files are:\n\t" + '\n\t'.join(files)
    content.append(body)
    return content
  else :
    content.append("DB Backup Failed")
    body = "\nThe last backup sucessfull file is " + files[-1]
    content.append(body)
    return content  
def main():
   
  #server = 'smtp.office365.com'
  #sender = 'online@netbraintech.com'
  #receiver = ['gavin.yuan@netbraintech.com' , 'feng.liu@netbraintech.com']
  #pwd = 'Netbrain12'
   
  config = ConfigParser()
  config.read_file(open('config.ini'))
  path = config.get('os', 'path')
  receiver = config.get('email', 'receiver')
  server = config.get('email', 'server')
  sender = config.get('email', 'sender')
  pwd = config.get('email', 'pwd')   
  content = MailContent(path,12)
  #content = MailContent("D:\\test",6)
  mail_content = content[1]   
  msg = MIMEText(mail_content, "plain", "utf-8")
  msg["Subject"] = Header(content[0], "utf-8")
  msg["From"] = sender
  msg["To"] = Header(receiver)   
  SendMail(server,sender,pwd,receiver.split(','),msg.as_string()) 
if __name__ == '__main__':
  main()

脚本依赖一个INI格式的配置文件来存储参数。

[os]
path=D:\test
[email]
server=smtp.office365.com
sender=xxxx@outlook.com
pwd=xxxxx
receiver=xx@outlook.com,xxxxx@gmail.com
