This article mainly explains "how to monitor the status of multi-source replication and concurrent mail by python2". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how python2 monitors the status of multi-source replication and concurrent mail".

Multi-source replication is used in our environment, so write a Python script to check the status. Python is 2.6.6 included in the system. The content of the email is in html format, and the interlacing changes color. The script is as follows:

#-*-coding: UTF-8-*-import smtplibfrom email.mime.text import MIMETextfrom email.header import Headerimport datetimeimport MySQLdbdate_end = datetime.date.today () html_part1 = "" Report of 10.10.100.10 multi source repl status {current_time} Master_Host Slave_IO_Running Slave_SQL_Running Seconds_Behind_Master Channel_Name "" .format (current_time=date_end) html_part2 = "td_bgcolor_num = 1db = MySQLdb.connect (" 10.10.100.10 " "mysqldba", "mysql-dba-168") cursor = db.cursor () cursor.execute ("show slave status") results = cursor.fetchall () with open ('/ tmp/slavesof10010.html' Mode='w') as f: f.write (html_part1) for row in results: Master_Host = row [1] Slave_IO_Running = row [10] Slave_SQL_Running = row [11] Seconds_Behind_Master = row [32] Channel_Name = row [- 2] if td_bgcolor_num%2==0: td_bgcolor='#F0F0F0' Else: td_bgcolor='#FFFFCE' td_bgcolor_num + = 1 pro ='+ row [1] .encode ('utf-8' Ignore') + "+ row [10] .encode ('utf-8','ignore') +" +' + row [11] .encode ('utf-8') 'ignore') + "+' + str (row [32]) +" +'+ Channel_Name + 'f.write (pro) f.write (html_part2) db.close () mail_host= "smtp.xxxx.com" sender =' devops@xxxx.com'receivers = ['devops@xxxx.com','123456789@qq.com'] With open ('/ tmp/slavesof10010.html',mode='r') as f: html=f.read () message = MIMEText (html, 'html') message [' From'] = Header ("devops@xxxx.com") message ['To'] = Header (" ".join (v for v in receivers) subject = 'multi-source-repl of 100.10 summary' message ['Subject'] = Header (subject,' utf-8') try: smtpObj = smtplib.SMTP () smtpObj.connect (mail_host, 25) # 25 is SMTP port number smtpObj.sendmail (sender, receivers, message.as_string () print" message sent successfully "except smtplib.SMTPException as e: print" Error: unable to send message ", print e
