服务器巡检shell脚本，python生成excel文档并邮件发出
背景及思路：
五一小长假之前，公司要求我做一次服务器巡检。
1、写了一个简单的脚本获取服务器的各种基础信息：cpu，内存，swap分区使用情况，磁盘，网卡信息种种，具体见脚本，将这些信息追加到一个文件中，然后在监控机上做一次汇总，汇总方式就不详谈，我用的是for循环ssh追加
2、然后利用python的xlsxwriter模块生成excel
3、最后利用python发带附件为excel的邮件到指定邮箱
获取服务器信息部分脚本：
#取所需要的内网IP
Int_ip=`ifconfig|awk '/inet addr/ {gsub(/:/," ");print $3}'|egrep "^192.168.18"|head -1`
#取除该内网ip以及127.0.0.1之外的所有ip
Out_ip_list=`ifconfig|awk '/inet addr/ {gsub(/:/," ");print $3}'|grep -v $Int_ip|grep -v 127.0.0.1`
#取内存总值，单位为G，四舍五入
Memory=`free -m|awk '/Mem/ {printf ("%.f\n",$2/1024)}'`
#取内存fr
ee值，从系统角度看，取的是第一行的free
Memory_free=`free -m|awk '/Mem/ {printf "%.f\n",$4/1024}'`
#取CPU核数
Cpu_num=`grep processor /proc/cpuinfo|wc -l`
#取服务器运行时间
Uptime=`uptime|awk '{print $3}'`
#取最近15分的负载
Load=`uptime|awk '{print $12}'`
#取磁盘大于80%的磁盘目录
Disk=`df -h|awk '{a=+$(NF-1);if(a>=80)print $NF}'`
#swap分区总值，单位为G，四舍五入
Swap=`free -m|awk '/Swap/ {printf ("%.f\n",$2/1024)}'`
#swap分区
Swap_free=`free -m|awk '/Swap/ {printf "%.f\n",$4/1024}'`
生成excel
excel.py:
#!/usr/bin/python
# -*- coding: utf-8 -*-
from xlsxwriter import workbook
import ConfigParser
import time
import sendmail
def write_excel(file):
'''
1、设置 Excel 样式
2、将数据写入到 Excel 中
'''
# 生成 Excel 文件
work = workbook.Workbook(file)
# 建立工作表，表名默认
worksheet = work.add_worksheet()
# 设置字体加粗、字体大小
format_title = work.add_format({'bold': True, 'font_size': 16})
# 设置水平对齐、垂直对齐
format_title.set_align('center')
format_title.set_align('vcenter')
format_body = work.add_format({'font_size': 14})
# 设置样式，行高、列宽
worksheet.set_row(0, 25)
worksheet.set_column(0, 7, 30)
worksheet.set_column(8,9,50)
worksheet.set_column(9,10,100)
# 定义表头
title = (
'服务器IP',
'内存大小 GB',
'内存剩余 GB',
'Swap大小 GB',
'Swap剩余 GB',
'运行时间 天',
'系统负载 ',
'CPU 核数',
'磁盘超过80%',
'其余IP',
)
row = 0
col = 0
#写入表头
for item in title:
item = unicode(item,"utf-8")
worksheet.write(row, col, item, format_title)
col+=1
#写入数据
cf = ConfigParser.ConfigParser()
cf.read('/data/scripts/excel/config_total.txt')
for ip in cf.sections():
row+=1
col = 0
for opt in cf.options(ip):
key=cf.get(ip,opt)
worksheet.write(row,col,key,format_body)
col+=1
work.close()
if __name__ == '__main__':
Excel_name = "Server_%s.xls" %(time.strftime("%Y-%m-%d", time.localtime()))
write_excel(Excel_name)
sendmail.send_mail('********@139.com','服务器巡检表格','fuliao server message',Excel_name)
sendmail.py:
#!/usr/bin/python
import smtplib
from email.header import Header
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.application import MIMEApplication
import sys
mail_host = 'smtp.163.com'
mail_user = '163邮箱账号'
mail_pass = '163邮箱密码'
mail_postfix = '163.com'
def send_mail(to_list,subject,content,name):
me = mail_user+"<"+mail_user+"@"+mail_postfix+">"
msg = MIMEMultipart()
msg['Subject'] = subject
msg['From'] = me
msg['to'] = to_list
msg.attach(MIMEText(content))
part = MIMEApplication(open(name,'rb').read())
part.add_header('Content-Disposition','attachment', filename=name)
msg.attach(part)
try:
s = smtplib.SMTP()
s.connect(mail_host)
s.login(mail_user,mail_pass)
s.sendmail(me,to_list,msg.as_string())
s.close()
return True
except Exception,e:
print str(e)
return False
最后生成的excel图：
效果在上面
