Automatic slow query and Analysis Based on Python and automatic mail sending

Automatic slow query and Analysis Based on Python and automatic mail sending
Consists of two program files. The first program implements slow query analysis and file upload.

# Finally, the client's local email sending program is called to send the slow query log that has just been captured to the Administrator as an email attachment. Local ('/root/tuchao/sendma. py') the second program sends the analyzed logs as email attachments to the Administrator.

Constructing a mail object is a mescript object. Constructing a MIMEText object means that a text mail object constructs a MIMEImage object, which means that an image as an attachment should combine multiple objects, you can use the MIMEMultipart object MIMEBase to represent any object.
