aws 预留实例到期监控

环境准备

安装python的aws 开发工具包

pip install boto3

配置aws账号

[root@zabbix service]# aws configure
AWS Access Key ID [None]: xxxxxx
AWS Secret Access Key [None]: xxxxx
Default region name [None]:
Default output format [None]:

监控脚本：

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import boto3,os
import datetime
from ReservedInstancesMonitor_message import *
def reserved_instances_info():
    data=response['ReservedInstances']
    #send_message=""
    reserved_instances_number=0
    for info in data:
        #购买时长
        purchase_time=info['Duration']
        #购买起始时间
        purchase_start_time=info['Start']
        #print(purchase_time,purchase_start_time)
        #获取当前时间
        current_time=datetime.datetime.now()
        #print(current_time)
        #获取过期时间
        retired_time=datetime.datetime.strptime( str(purchase_start_time).split('+')[0],"%Y-%m-%d %H:%M:%S.%f") + datetime.timedelta(seconds=purchase_time)
        #剩余过期时间
        retired_left_time=(retired_time -current_time).days
        if retired_left_time <= 7:
           #send_message +=info['InstanceType'] +" "+str(info['InstanceCount'])+"\n"
            reserved_instances_number+=info['InstanceCount']
        #print("预留实例类型:   " + info['InstanceType'],"   过期数量:   ",info['InstanceCount']   ,"   多少天后过期:  " , retired_left_time)
    return reserved_instances_number
if __name__=='__main__':
    region_list=['ap-northeast-2','eu-central-1']
    for region in region_list:
        print("-"*100)
        client=boto3.client('ec2',region_name=region)
        response = client.describe_reserved_instances(Filters=[{'Name':'state','Values':['active',]},])
        instances_number=reserved_instances_info()
        if instances_number != 0:
           message="【xx告警】区域: " +region+ " " + str(instances_number) +" "+ "台预留实例将于7天后到期,请及时购置!"
           print (message)
           send_sms(apikey,message,mobile)

发短信脚本(使用的云片网接口)：

#!/usr/bin/python
#-*- coding:utf-8 -*-
# apikey:成功注册后登录云片官网,进入后台可查看
# text:需要使用已审核通过的模板或者默认模板
# mobile:接收的手机号,仅支持单号码发送
import os
import urllib,urllib2,httplib,time
from subprocess import Popen,PIPE
apikey='xxxx'
mobile='xxxx'
def send_sms(apikey, text, mobile):
     #服务地址
     sms_host = "sms.yunpian.com"
     #端口号
     port = 443
     #版本号
     version = "v2"
     #智能匹配模板短信接口的URI
     sms_send_uri = "/" + version + "/sms/single_send.json"
     params = urllib.urlencode({'apikey': apikey, 'text': text, 'mobile':mobile})
     headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}
     conn = httplib.HTTPSConnection(sms_host, port=port, timeout=30)
     conn.request("POST", sms_send_uri, params, headers)
     response = conn.getresponse()
     response_str = response.read()
     conn.close()
     return response_str
if __name__=='__main__':
     pass
     #message="【xx告警】区域: %s %s 台预留实例将于7天后到期,请及时购置!" %(region,instances_number)
     #print send_message
     #send_sms(apikey,message,mobile)

云片网配置短信模板

【xx告警】区域: #region# #instance_number# 台预留实例将于7天后到期,请及时购置!

将过期时间调长，测试脚本执行

开启定时任务：
