首页 / 数据库 / MySQL / 利用Python 发送MySQL 慢日志邮件
一 需求
因为开发针对某系统做稳定性建设,需要对数据库系统的慢日志进行审计,检查优化。和开发沟通选择定期发送慢查询到开发的邮箱的方式,每日汇总,然后一起评估 优化slow query 。二 工具实现
mail.py 脚本#!/usr/bin/env python
# -*- coding: utf-8 -*-# mail.pyimport os.pathimport timeimport sysimport osimport jsonimport stringimport randomimport smtplibimport timefrom datetime import datefrom email.mime.multipart import MIMEMultipartfrom email.mime.text import MIMETextfrom email.mime.image import MIMEImagefrom email.Header import Headerfrom email.MIMEText import MIMETextfrom email.MIMEMultipart import MIMEMultipart mail_user="xxx@xxxx.com";mail_pass="xxxxx";mail_smtp_server="smtp.xxxxx.com";mail_smtp_port= 25 def sendMail(contents,subject,attach,mail_to): lTime=str(time.strftime("%Y%m%d_%H",time.localtime(time.time()))) msg = MIMEMultipart("related"); if subject=="": subject="test"; msg["Subject"] = subject+" Time:"+ lTime; msg["From"] = mail_user; msg["To"] = ";".join(mail_to) ; html=""; for cont in contents: html = html+cont[0]; msgHtml = MIMEMultipart("alternative"); msgHtml.set_charset("UTF-8"); msgAtt = MIMEText(open(attach,"rb").read(),"base","gbk"); msgAtt["Content-Type"] = "application/octet-stream" msgAtt["Content-Disposition"] = "attachment; filename=""+subject+""" msg.attach(msgAtt); try: smtp = smtplib.SMTP(); smtp.connect(mail_smtp_server,mail_smtp_port) smtp.login(mail_user,mail_pass); smtp.sendmail(mail_user,mail_to,msg.as_string()); smtp.close(); except Exception,e: print str(e)
sendSlowlog.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-import mail ##使用了上述脚本import sysimport timeimport osimport datetime from datetime import datefrom os.path import join, getsize def sendSlowlog(subject_info,attach,mail_to): size = os.path.getsize(attach) if(size > 1): mail.sendMail("",subject_info,attach,mail_to) if __name__ == "__main__": mail_to=["qilong.yangql@xxxx.com"] lDate=str(time.strftime("%Y%m%d",time.localtime(time.time()))) lTime=str(time.strftime("%Y%m%d_%H",time.localtime(time.time()))) subject_info="Slowlog of DBname" + lTime attach="/u01/my3306/log/slow_"+ lDate +"/slow.log."+lTime sendSlowlog(subject_info,attach,mail_to)注
本系统已经每小时将slow log 进行分割,关于如何切割,各位可以思考一下。本文永久更新链接地址
