python利用saltstack检测所管理服务器的硬盘状态

一、在linux中安装saltstack

　　见此saltstack的安装博文https://www.cnblogs.com/feilu---python/p/11982951.html

二、配置python邮件发送程序

　　代码如下：

#!/usr/bin/env python
#-*- coding:utf-8 -*-
# datetime: 2019/11/4 13:31
# software: PyCharm
import smtplib, sys
from email.mime.text import MIMEText
import argparse
parser = argparse.ArgumentParser(description='manual to this script')
parser.add_argument('-S','--subject_title', type=str, default = None)
parser.add_argument('-s','--subject', type=str, default=None)
args = parser.parse_args()
class Msmtp():
    def __init__(self, target, subject, content): # 收件人、标题、内容
        self.msg_from = 'xxx@qq.com'  # 邮件发送者
        self.password = 'passwd'
        self.sender = smtplib.SMTP_SSL("smtp.exmail.qq.com", 465)
        self.msg_to = target.split(",")
        self.subject = subject
        self.content = content

    def login(self):
        self.sender.login(self.msg_from, self.password)  # 邮箱登录

    def msg(self):
        self.msg = MIMEText(self.content)  # 此处可选择文本格式或html等格式, 显示发送信息
        self.msg['Subject'] = self.subject
        self.msg['From'] = self.msg_from
        self.msg['To'] = ",".join(self.msg_to)

    def send_mail(self):
        try:
            self.login()
            self.msg()
            # sendmail 第二个参数，目的邮箱，参数类型 str 或者 list
            self.sender.sendmail(self.msg_from, self.msg_to, self.msg.as_string())
        except Exception as e:
            print(u'邮件发送失败，原因：{}'.format(e))
        else:
            # print(u'邮件发送至 {} 成功！'.format(self.msg['To']))
            pass
        finally:
            self.sender.quit()

if __name__ == '__main__':
    # 收件人， 标题， 内容
    receivers = xxx@qq.com'
    title = "测试"
    subject = "测试"
    # a = Msmtp(sys.argv[1], sys.argv[2], sys.argv[3])
    a = Msmtp(receivers, title, subject)  # receivers收件人
    a.send_mail()

三、磁盘检测代码

#!/usr/bin/env python
#-*- coding:utf-8 -*-
# datetime: 2019/11/5 14:24
# software: PyCharm
import salt.client
import send_mail_mod
remote_server_name = '*'
remost_cmd = 'df -h |grep -v Filesystem |grep -v tmpfs |grep -v /var/lib/docker |grep -v %0'
salt_client = salt.client.LocalClient()
# 获取执行命令后的所有的服务的建
server_host = salt_client.cmd(remote_server_name,'cmd.run',[remost_cmd])
disk_list_info = []
def disk_dir_free(disk_new_list):
    # 获取某个挂载目录的剩余量的值
    while '' in disk_new_list:
        disk_new_list.remove('')
    #     移除列表中的空元素
    # while循环是为了取出新列表中的空元素
    disk_free = disk_new_list[4]
    # 获取第五位的磁盘剩余量
    disk_free_num = disk_free.replace('%', '')
    return disk_free_num
def disk_check(keys):
    # 删除字符串中的空字符并形成一个列表
    for disk_pro in keys:
        disk_new_list = disk_pro.split(' ')
        disk_num = disk_dir_free(disk_new_list)
        if disk_num.isdigit():
            if int(disk_num) > 70:
                info = ''.join(('*服务器：'+serverhost,'  *磁盘名称: '+disk_new_list[0],
                         '  *总容量：' + disk_new_list[1],'  *剩余容量：'+disk_new_list[3],
                         '  *使用率：'+disk_new_list[4],'  *挂载目录：' + disk_new_list[5]))
                disk_list_info.append(info)

        # 如果磁盘容量大于某个数值就报警
for serverhost in server_host.keys():
    disk_dev = server_host[serverhost].splitlines()
    # 将获取的值以'/n'分割
    disk_check(disk_dev)

if len(disk_list_info) > 0 :
    infomation = '\n'.join(tuple(disk_list_info))
    receivers = 'xxx@qq.com'
    title = serverhost + '生产环境磁盘使用率'
    a = send_mail_mod.Msmtp(receivers, title, infomation)  # receivers收件人
    a.send_mail()

四、邮件发送需要和检测程序放置在相同目录下。
五、放置在定时任务中

            self.sender.sendmail(self.msg_from, self.msg_to, self.msg.as_string())
        except Exception as e:
            print(u'邮件发送失败，原因：{}'.format(e))
        else:
