前言：运维工作中，我们经常需要将一些数据每天自动的发送到邮箱，比如网站的pv/uv、网站的状态码统计，或是一些其他日常监控数据的统计等，为了更方便的查看，我们采取用表格形式发到邮箱，这样既清晰有直观。
1、数据准备
- 我写了一个shell统计脚本，用于统计各个网站的状态码数量，刚开始是直接输出结果，后来为了方便python拿数据，于是稍作修改,代码如下：
#!/bin/bash
#
index_name=logstash-$(date -d "-1 day -8 hour" "+%Y.%m.%d")
#网站换成自己的网站，数据实际是通过elk收集，通过查询生成的json
for server in www.baidu.com www.360.com www.jd.com www.taobao.com
do
sed -i "14 s#\"query\": \".*\",#\"query\": \"$server\",#" vd-23.json #2xx和3xx状态码
sed -i "14 s#\"query\": \".*\",#\"query\": \"$server\",#" vd-45.json #4xx和5xx状态码
sed -i "11 s#\"query\": \".*\",#\"query\": \"$server\",#" vd-all.json #总数
#
t2_count=`curl -s -XPOST -H 'content-type: application/json' -d@/data/sh/vd-23.json http://www.elk.com:9200/${index_name}/_search?search_type=count|jq ".hits.total"`
f4_count=`curl -s -XPOST -H 'content-type: application/json' -d@/data/sh/vd-45.json http://www.elk.com:9200/${index_name}/_search?search_type=count|jq ".hits.total"`
all_count=`curl -s -XPOST -H 'content-type: application/json' -d@/data/sh/vd-all.json http://www.elk.com:9200/${index_name}/_search?search_type=count|jq ".hits.total"`
#
#变量本来是分开打的，后来改成全打在一行，其实可以考虑打成json格式，python更容易取
echo -n "$t2_count,`echo "$t2_count $all_count"|awk '{printf "%.4f%\n",$1/$2*100}'`,$f4_count,`echo "$f4_count $all_count"|awk '{printf "%.4f%\n",$1/$2*100}'`,$all_count,"
done
得到的数据是一堆用 , 连起来的数据，如下
11038332,91.0479%,1632,0.0135%,12123654,8143047,99.9921%,643,0.0079%,8143690,4558407,99.9964%,165,0.0036%,4558572,8336274,99.9991%,79,0.0009%,8336353,
2、分析数据
- os.popen执行shell
import os
a=os.popen("bash /data/sh/md_sla.sh").read()
print a.strip('\n').split(',')
得到一串list
取值直接用list的方式取
3、取值并发送邮件
- 发送邮件在 PhantomJS按尺寸截取页面，并用python发送邮件 讲过，下面直接上代码：
#!/usr/bin/env python
#coding:utf8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email import encoders
import sys
import os
from datetime import *
#
def send_mail(to_list, sub):
me = mail_user
msg = MIMEMultipart()
msg['Subject'] = sub
msg['From'] = me
msg['To'] = ",".join(to_list)
#创造数据
a=os.popen("bash /data/sh/md_sla.sh").read().strip('\n').split(',')
#构造html
d = datetime.now()
dt = d.strftime('%Y-%m-%d %H:%M:%S')
at = (d - timedelta(1)).strftime('%Y-%m-%d %H:%M:%S')
timezone = at + ' ~ ' + dt
#构造html
html = """\

msg.attach(context)
try:
send_smtp = smtplib.SMTP()
send_smtp.connect(mail_host)
send_smtp.login(mail_user, mail_pass)

- 发送结果如下：

好了，结束，做个计划任务
