Python腳本實作郵件報警功能
使用了smtplib等第三方庫,進行發送郵件,完成郵件報警功能
如下是實體 :
#!/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 = ""
#主方法
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()
#這里監控檔案夾下的檔案數,超出25個檔案即報警
datanum = cntFiles("/data/","csv")
if (operator.gt(datanum,25)):
msg += " Please be alert : \n the number of files under /data/ path is greater than 25 :"
msg += "\n =========================================="
msg += "\n The number of files is : " + str(datanum)
sendmsg(options,msg)
print("==== end ====")
#添加發送郵件的資訊
def sendmsg(options,msg):
if options.mail:
toAddr = options.mail
if options.admin:
fromAddr = options.admin
else:
fromAddr = '[email protected]'#這里是公司的公用SMTP郵箱賬號
if options.title:
subject = options.title
else:
subject = 'File Stacking Alarm'
msg += "\n ========================================== \n"
print( msg)
msg = createMsg(fromAddr, toAddr, subject, msg)
print( msg)
send(fromAddr, toAddr, msg)
else:
print( msg)
#glob方法,統計檔案夾下的檔案數
def cntFiles(in_directory, ext):
stage = len(glob.glob1(in_directory,"*." + ext))
return stage
#創建郵件頭
def createMsg(fromAddr, toAddr, subject, body):
msg = MIMEText(body)
msg['Subject'] = subject
msg['To'] = toAddr
msg['From'] = fromAddr
msg['Date'] = formatdate()
return msg
#發送郵件
def send(fromAddr, toAddr, msg):
try:
#這里添加公司的SMTP郵箱地址
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上做計劃任務,把指令添加進計劃任務中:
Errymsfileemail.py -m [email protected] -t "[ERROR/$HOST] File Stacking Alarm"
