## 磁盘容量监控python脚本实现 ##

需求：检测`/data`路径下的磁盘容量是否超出阈值，超出阈值，发送邮件通知。

代码：`diskcheck.py`

#!/usr/bin/env python
    # -*- coding: utf-8 -*-
    import smtplib
    import socket
    from email.mime.text import MIMEText
    from email.header import Header
    import psutil
    
    # 磁盘阈值
    disk_limit = 80
    # 监控磁盘的路径
    disk_path = "/data"
    
    
    def get_host_ip():
        """
        查询本机ip地址
        :return: ip
        """
        global s
        try:
            s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
            s.connect(('8.8.8.8', 80))
            ip = s.getsockname()[0]
        finally:
            s.close()
        return ip
    
    
    def send_email():
        """
        发送邮件代码
        """
    
        ip = get_host_ip()
    
        print(ip)
    
        # 发送者的邮箱
        sender = 'xxxxxx@xxxxxx.com'
        # 接受者的邮箱
        receivers = ['xxxxxxx@xxxxxx.com']
    
        message = MIMEText('%s 机器磁盘超出阈值' % ip, 'plain', 'utf-8')
        message['From'] = Header("磁盘容量超出阈值警告", 'utf-8')
        message['To'] = Header("Admin", 'utf-8')
        message['Subject'] = Header('磁盘容量超出阈值警告', 'utf-8')
    
        try:
            smtpObj = smtplib.SMTP()
            # domain指公司域名
            smtpObj.connect("mail.domain.com", 25)
            # smtp的用户登入账号
            smtpObj.login("user", "password")
            smtpObj.sendmail(sender, receivers, message.as_string())
            print "邮件发送成功"
        except smtplib.SMTPException:
            print "Error: 无法发送邮件"
    
    
    def monitor_disk():
        """
        disk_usage判断是否超出界限值
        """
        global disk_limit
        global disk_path
        disk_percent = psutil.disk_usage(disk_path).percent
        if disk_percent > disk_limit:
            send_email()
        else:
            print("Disk space usage: {}%".format(disk_percent))
    
    
    if __name__ == '__main__':
        monitor_disk()
