Pythonスクリプトに基づいてメールアラーム機能を実現します。

smatplibなどの第三者ライブラリを使ってメールを送り、メールアラーム機能を完成させました。
実例は以下の通りです

#!/usr/bin/python
 
import glob
import operator
from optparse import OptionParser
import smtplib
import email.MIMEText as MIMEText
import email.Utils.formadate as formatdate
 
msg = ""
#   
def main():
  global options
  global msg
 
  parser = OptionParser(add_help_option=False)
  parser.add_option("-m", "--mail", dest="mail", type="str", help="email address to send report result (comma separated)")
  parser.add_option("-t", "--title", dest="title", type="str", help="email title (default:Error File Count)")
  parser.add_option("-a", "--admin", dest="admin", type="str", help="set sender address. works with -m option")
  (options, args) = parser.parse_args()
 
  #            ,  25      
  datanum = cntFiles("/data/","csv")
  if (operator.gt(datanum,25)):
    msg += " Please be alert : 
 the number of files under /data/ path is greater than 25 :"
    msg += "
 =========================================="
    msg += "
 The number of files is : " + str(datanum)
    sendmsg(options,msg)
  print("==== end ====")
 
#         
def sendmsg(options,msg):
  if options.mail:
    toAddr = options.mail
    if options.admin:
      fromAddr = options.admin
    else:
      fromAddr = '[email protected]'#        SMTP    
 
    if options.title:
      subject = options.title
    else:
      subject = 'File Stacking Alarm'
    msg += "
 ========================================== 
"
    print( msg)
    msg = createMsg(fromAddr, toAddr, subject, msg)
    print( msg)
    send(fromAddr, toAddr, msg)
  else:
    print( msg)
 
#glob  ,          
def cntFiles(in_directory, ext):
  stage = len(glob.glob1(in_directory,"*." + ext))
  return stage
 
#     
def createMsg(fromAddr, toAddr, subject, body):
  msg = MIMEText(body)
  msg['Subject'] = subject
  msg['To'] = toAddr
  msg['From'] = fromAddr
  msg['Date'] = formatdate()
  return msg
 
#    
def send(fromAddr, toAddr, msg):
  try:
    #       SMTP    
     s = smtplib.SMTP('192.168.12.120')
     s.sendmail(fromAddr, toAddr.split(','), msg.as_string())
     s.close()
     print("SUCCESS: sending email")
  except smtplib.SMTPException:
     print("ERROR: sending email")
 
if __name__ == '__main__':
  main()

linuxで計画的なタスクを行い、命令を計画的なタスクに追加します。
