python2监控多源复制状态并发邮件

2019-09-09 17:12 1311 查看

我们环境中用到了多源复制，因此写个查看状态的Python脚本，python为系统中自带的2.6.6，邮件内容为html格式，隔行变色，脚本如下：

# -*- coding: UTF-8 -*-
import smtplib
from email.mime.text import MIMEText
from email.header import Header
import datetime
import MySQLdb
date_end = datetime.date.today()
html_part1 = """
<html>
<head></head>
<body><h2>Report of 10.10.100.10 multi source repl status {current_time}</h2>
<table border=\"1\" bordercolor=\"#000000\" width=\"350\"  style=\"width:85%;BORDER-COLLAPSE: collapse\" >
<tbody>
<tr style="color:White" bgColor=#0066CC>
<th>Master_Host</th>
<th>Slave_IO_Running</th>
<th>Slave_SQL_Running</th>
<th>Seconds_Behind_Master</th>
<th>Channel_Name</th>
</tr>
""".format(current_time=date_end)

html_part2 = """
</body>
</html>
"""
td_bgcolor_num = 1
db = 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 = '''
<tr bgcolor="'''+td_bgcolor+'''" align=\"center\" >
<td style="width: 20%;">'''+ row[1].encode('utf-8','ignore') + "</td>" + '''
<td style="width: 15%;">'''+ row[10].encode('utf-8','ignore') + "</td>" + '''
<td style="width: 15%;">'''+ row[11].encode('utf-8','ignore') + "</td>" + '''
<td style="width: 15%;">'''+ str(row[32]) + "</td>" + '''
<td style="width: 20%;">'''+ Channel_Name + '''</td>
</tr>
'''
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','126@126.com','163@163.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汇总'
message['Subject'] = Header(subject, 'utf-8')

try:
smtpObj = smtplib.SMTP()
smtpObj.connect(mail_host, 25)    # 25 为 SMTP 端口号
smtpObj.sendmail(sender, receivers, message.as_string())
print "邮件发送成功"
except smtplib.SMTPException as e:
print "Error: 无法发送邮件",
print e
