详解三类网站状态监控的方式以及使用iis7网站监控脚本的方法。
西安seo常见的方法莫过于wget和curl命令了，这两个命令都是非常强大的，强大到网友查看帮助都无从选择的地步了，今天呢，天成网络为大家分享Shell编程实战方法，
网站状态监控有多种方法，大体上可以分成三类：
1、自己写脚本监控，去网上找一个写的比较好的，改一改也行呀
2、通过开源的第三方的工具，比如zabbix结合grafana
3、通过商业工具，比如：友盟统计
4、IIS7网站监控可以及时防控网站风险，快速准确监控网站是否遭到各种劫持攻击，网站在全国是否能正常打开（查看域名是否被墙），精准的DNS污染检测，具备网站打开速度检测功能，第一时间知道网站是否被黑、被入侵、被改标题、被挂黑链。精益求精的产品，缺陷为零数据提供！
它可以做到以下功能：
1、检测网站是否被黑
2、检测网站是否被劫持
3、检测域名是否被墙
4、检测DNS是否被污染
5、网站真实的完全打开时间（独家）
6、拥有独立监控后台，24小时定时监控域名

1、状态码监控脚本
下面这个脚本相当简单了，就只能检测网站的的状态码，如果状态码不是200就会发邮件通知我们，每两分钟检测一次。
#!/bin/bash
date=`date +"%Y%m%d-%H%M"`
title="status"
contentFail="status is not ok:"
contentSuccess="status is ok:"
url="Welcome"#通过下面这条命令可以取出状态码
status=`curl -m 20 -s -I $url | grep HTTP | awk '{print $2}'`
#echo "status: $status"
cd /data/shell
laststatus=`cat status.log`
if [ "$status" == "200" ]
then
if [ "$laststatus" != 200 ]
then
/usr/bin/python /shell/mail.py "$title" "$contentSuccess $url $date $status"
echo "200" > status.log
fielse
if [ "$laststatus" == 200 ]
then
/usr/bin/python /shell/mail.py "$title" "$contentFail $url $date $status"
echo "$status" > status.log

def sendmail(subject, content):
sender = 'abc@163.com'
password = 'abc'
recipients = 'abc@qq.com'
host = 'smtp.abc.com'
msg = MIMEText(content, 'plain', 'utf-8')
msg['From'] = sender
msg['To'] = recipients
msg['Subject'] = Header(subject, 'utf-8').encode()
server = smtplib.SMTP_SSL(host, 465)
server.login(sender, password)
server.sendmail(sender, [recipients], msg.as_string())
server.quit()
sendmail(sys.argv[1],sys.argv[2])

2、超时时间监控脚本
[root@qd-inf-logcollector01 web_monit]$ pwd
/app/script/web_monit
[root@qd-inf-logcollector01 web_monit]$ ll
total 12
-rwxr-xr-x 1 root root 870 Oct 12 21:34 http_monit.sh //监控脚本
-rwxr-xr-x 1 root root 857 Oct 12 21:25 sms.py //短信报警脚本，里面有报警联系人
-rw-r--r-- 1 root root 377 Oct 12 21:27 weblist.txt //监控的网站域名列表
[root@qd-inf-logcollector01 web_monit]$ cat http_monit.sh#!/bin/sh
weblist=/app/script/web_monit/weblist.txt for list in `cat $weblist|grep -E -v "#|^$"` do
httpcode=`curl -o /dev/null -s -w %{http_code} "$list"`
httptime=`curl -o /dev/null -s -w "time_connect: %{time_connect}\ntime_starttransfer: %{time_starttransfer}\ntime_total: %{time_total}\n" "$list"|grep time_total|awk -F ":" '{print $2*1000}'`if [ $httpcode = 500 ]||[ $httpcode = 502 ]||[ $httpcode = 503 ]||[ $httpcode = 504 ]
then
python /app/script/web_monit/sms.py $list "$list 访问有误!状态码为$httpcode!请收到报警后尽快查看并处理!"else
echo "$list is checked ok!"
fi
if [ $httptime -ge 10000 ]
then
python /app/script/web_monit/sms.py $list " $list访问超时!超时时间为$httptime毫秒!请收到报警后尽快查看并处理!"else
echo "$list is connect ok!"
fi
done
////小案例
[11:01root@kk ~]# curl -o /dev/null -s -w %{time_namelookup}---%{time_connect}---%{time_starttransfer}---%{time_total}---%{speed_download}"\n" www.baidu.com0.013---0.035---0.058---0.058---40709.000
[11:02root@kk ~]# curl -o /dev/null -s -w %{time_namelookup}---%{time_connect}---%{time_starttransfer}---%{time_total}---%{speed_download}"\n" www.zhanghehe.cn0.063---1.436---2.797---2.797---60.000
-o：把curl 返回的html、js 写到垃圾回收站[ /dev/null]
-s：去掉所有状态
-w：按照后面的格式写出rt
time_namelookup：DNS 解析域名http://www.36nu.com的时间
time_commect：client和server端建立TCP 连接的时间
time_starttransfer：从client发出请求；到web的server 响应第一个字节的时间
time_total：client发出请求；到web的server发送会所有的相应数据的时间
speed_download：下周速度 单位 byte/s
上面这条命令及返回结果可以这么理解：
0.015: client发出请求，到c/s 建立TCP 的时间；里面包括DNS解析的时间
0.018: client发出请求；到s响应发出第一个字节开始的时间；包括前面的2个时间
0.019: client发出请求；到s把响应的数据全部发送给client；并关闭connect的时间
1516256.00 ：下载数据的速度
建立TCP连接到server返回client第一个字节的时间：0.018s – 0.015s = 0.003s
server把响应数据发送给client的时间：0.019s – 0.018 = 0.01s
curl的部分时间等变量注释：
url_effective The URL that was fetched last. This is most meaningful if you've told curl to follow location: headers.
filename_effective The ultimate filename that curl writes out to. This is only meaningful if curl is told to write to a file with the --remote-name or --output option. It's most useful in combination with the --remote-header-name option. (Added in 7.25.1)
http_code http状态码，如200成功,301转向,404未找到,500服务器错误等。(The numerical response code that was found in the last retrieved HTTP(S) or FTP(s) transfer. In 7.18.2 the alias response_code was added to show the same info.)
http_connect The numerical code that was found in the last response (from a proxy) to a curl CONNECT request. (Added in 7.12.4)
time_total 总时间，按秒计。精确到小数点后三位。 （The total time, in seconds, that the full operation lasted. The time will be displayed with millisecond resolution.）
time_namelookup DNS解析时间,从请求开始到DNS解析完毕所用时间。(The time, in seconds, it took from the start until the name resolving was completed.)
time_connect 连接时间,从开始到建立TCP连接完成所用时间,包括前边DNS解析时间，如果需要单纯的得到连接时间，用这个time_connect时间减去前边time_namelookup时间。以下同理，不再赘述。(The time, in seconds, it took from the start until the TCP connect to the remote host (or proxy) was completed.)
time_appconnect 连接建立完成时间，如SSL/SSH等建立连接或者完成三次握手时间。(The time, in seconds, it took from the start until the SSL/SSH/etc connect/handshake to the remote host was completed. (Added in 7.19.0))
time_pretransfer 从开始到准备传输的时间。(The time, in seconds, it took from the start until the file transfer was just about to begin. This includes all pre-transfer commands and negotiations that are specific to the particular protocol(s) involved.)
time_redirect 重定向时间，包括到最后一次传输前的几次重定向的DNS解析，连接，预传输，传输时间。(The time, in seconds, it took for all redirection steps include name lookup, connect, pretransfer and transfer before the final transaction was started. time_redirect shows the complete execution time for multiple redirections. (Added in 7.12.3))
time_starttransfer 开始传输时间。在client发出请求之后，Web 服务器返回数据的第一个字节所用的时间(The time, in seconds, it took from the start until the first byte was just about to be transferred. This includes time_pretransfer and also the time the server needed to calculate the result.)
size_download 下载大小。(The total amount of bytes that were downloaded.)
size_upload 上传大小。(The total amount of bytes that were uploaded.)
size_header 下载的header的大小(The total amount of bytes of the downloaded headers.)
size_request 请求的大小。(The total amount of bytes that were sent in the HTTP request.)
speed_download 下载速度，单位-字节每秒。(The average download speed that curl measured for the complete download. Bytes per second.)
speed_upload 上传速度,单位-字节每秒。(The average upload speed that curl measured for the complete upload. Bytes per second.)
content_type 就是content-Type，不用多说了，这是一个访问我博客首页返回的结果示例(text/html; charset=UTF-8)；(The Content-Type of the requested document, if there was any.)
num_connects Number of new connects made in the recent transfer. (Added in 7.12.3)
num_redirects Number of redirects that were followed in the request. (Added in 7.12.3)
redirect_url When a HTTP request was made without -L to follow redirects, this variable will show the actual URL a redirect would take you to. (Added in 7.18.2)
ftp_entry_path The initial path libcurl ended up in when logging on to the remote FTP server. (Added in 7.15.4)
ssl_verify_result ssl认证结果，返回0表示认证成功。( The result of the SSL peer certificate verification that was requested. 0 means the verification was successful. (Added in 7.19.0))
