使用Python在windows环境下获取Linux服务器的磁盘、内存等信息

最近想持续监服务器的测硬盘容量，但是又不想在服务器上东搞西搞，发现python有个paramiko可以连接linux,

# -*- coding: utf-8 -*-
# @Author  : mlp
# @File    : linux_email.py
import paramiko,re,time,smtplib
import smtplib
from email.mime.text import MIMEText
from email.header import Header
# HostIP = 地址
# username = 登录名
# passwd = 密码
#端口一般默认为22
def run(HostIP, username, passwd):
try:
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(HostIP, 22, username, passwd)
#连接测试
        #ssh.exec_command('ls')
        #print(u"%s 连接成功"%HostIP)
        #执行命令获取结果
 stdin, stdout, stderr = ssh.exec_command('df -h')
#result = stdout.read().decode()
 err = stderr.read()
        result = stdout.read()
        ssh.close()
#print(stdin, err)
        #print(stdout.read())
 aa = re.findall("[0-9]{1,2}%", result)
#print result   #直接查看服务器返回结果
 if int(aa[0].strip("%")) >= 50:
#print(u"************【注意】{0}服务器硬盘容量目前已使用{1}************\n".format(HostIP, aa[0]))
            # 输入Email地址和口令:
 from_addr = "mulipeng666@163.com"
 password = "mlp123456"
 # SMTP服务器地址:
 smtp_server = "smtp.163.com"
 # 收件人地址:
 to_addr = "1023739289@qq.com"
 msg = MIMEText(u"************【注意】{0}服务器硬盘容量目前已使用{1}************\n".format(HostIP, aa[0]), 'plain', 'utf-8')
            msg['From'] = "mlp<********@163.com>"
 msg['To'] = "***<******@qq.com>"
 subject = u'【注意】硬盘容量预警'
 msg['Subject'] = Header(subject, 'utf-8')
            server = smtplib.SMTP(smtp_server, 25)  # SMTP协议默认端口是25
 server.set_debuglevel(1)
            server.login(from_addr, password)
            server.sendmail(from_addr, [to_addr], msg.as_string())
print(u"邮件发送成功")
            server.quit()
else:
print(u"{}硬盘容量目前已使用{}\n".format(HostIP, aa[0]))
except Exception as ex:
print "\tError %s\n" % ex
if __name__ == '__main__':
print("--------------------------------------------------------------")
print u"开始连接"+time.strftime(u"当前日期:%Y年%m月%d日 %H:%M:%S",time.localtime(time.time()))
    #把地址和密码放在下面
    serverlist = {“***”：“******”}
for hostip in serverlist:
        run(HostIP=hostip, username="root", passwd=serverlist[hostip])
ok，凑活能用
