psutil（进程和系统实用程序）是一个跨平台的库，用于检索 Python中有关正在运行的进程和系统利用率（CPU，内存，磁盘，网络，传感器）的信息。它主要用于系统监视，概要分析和限制进程资源以及管理正在运行的进程。

1、安装psutil

pip3 install psutil    # python2用户直接使用pip install psutil

2、创建get_system_info.py文件，获取系统状态

 1 import psutil as p

 2

 3

 4 def memory(): # 获取内存信息

 5     info = p.virtual_memory()

 6     return info[2]

 7

 8

 9 def disk(): # 获取磁盘使用情况

10     info = p.disk_usage('/')

11     return info[-1], info[-2]

12

13

14 def cpu(): # 获取CPU使用率

15     info = p.cpu_percent(1)

16     return info

# 在此只使用了博主所需的相关功能，详细说明见 https://pypi.org/project/psutil/

3、创建邮件发送send_Email.py文件

 1 import smtplib

 2 from email.header import Header

 3 from email.mime.text import MIMEText

 4 from email.utils import formataddr

 5

 6

 7 class send_Email():

 8     def __init__(self, mail_host, mail_port, mail_user, mail_pass, sender):

 9         self.mail_host = mail_host

10         self.mail_port = mail_port

11         self.mail_user = mail_user

12         self.mail_pass = mail_pass

13         self.sender = sender

14

15     def make_mail(self, title, code, receiver): # 生成邮件

16         mail_msg = """

17         

%s

18         

%s

19         """ % (title, code)

20         self.message = MIMEText(mail_msg, "html", "utf-8")

21         self.message['From'] = formataddr(["XX", self.sender])

22         self.message['To'] = formataddr(["User", receiver])

23         subject = title

24         self.message['Subject'] = Header(subject, "utf-8")

25

26     def send(self, receiver, title, code): # 发送邮件

27         status = 0

28         self.make_mail(title, code, receiver)

29         try:

30             self.smtpObj = smtplib.SMTP_SSL(self.mail_host, self.mail_port)

31             # print(1)

32             self.smtpObj.login(self.mail_user, self.mail_pass)

33             # print(2)

34             self.smtpObj.sendmail(self.sender, [receiver], self.message.as_string())

35             self.smtpObj.quit()

36             status = 1

37         except smtplib.SMTPException as e:

38             print("Error！ 无法发送邮件！！！" + e)

39         return status

4、整合代码

from send_Email import send_Email

import get_system_info as gsi

email = send_Email("smtp.163.com", 465, "*******@***.com", "**********", "********@***.com") # 初始化

memory = gsi.memory()

disk, capacity = gsi.disk()

info = str(memory)+"     "+str(disk)+"     "+str(round(capacity/1024/1024/1024, 2))

email.send(code=info, title="系统状态异常", receiver="*******@***.***")

status_d = 0

status_m = 0

while True: # 实时检测系统状态，会占用一定的系统资源

    memory = gsi.memory()

    disk, capacity = gsi.disk()

    if memory >= 80 and status_m == 0:

        status_m = 1

        data = "当前内存占用率为"+str(memory)+"%，建议清理或扩充内存！"

        email.send(code=data, title="系统状态异常", receiver="*******@***.***")

    elif memory < 80:

        status_m = 0

    if disk >= 80 and status_d == 0:

        status_d = 1

        data = "当前硬盘已使用"+str(disk)+"%，剩余"+str(round(capacity/1024/1024/1024, 2))+"GB，请及时扩充！"

                                       if disk >=货币符号https://www.gendan5.com/currencyworld.html

        email.send(receiver="*******@***.***", title="系统状态异常", code=data)

    elif disk < 80:

        status_d = 0

    if memory >= 90 and status_m == 1:

        status_m = 2

        data = "当前内存占用率为"+str(memory)+"%，建议清理或扩充内存！"

        email.send(code=data, title="系统状态异常", receiver="*******@***.***")

    elif memory < 90:

        status_m = 1

    if disk >= 90 and status_d == 1:

        status_d = 2

        data = "当前硬盘已使用"+str(disk)+"%，剩余"+str(round(capacity/1024/1024/1024, 2))+"GB，请及时扩充！"

        email.send(receiver="*******@***.***", title="系统状态异常", code=data)

    elif disk < 90:

        status_d = 1
