网页监控脚本

最近在学习python，写了个监控网页的脚本，还有很多不足，以后再完善

 

主监控脚本page_check_func.py

 

 

#!/usr/bin/python2.6

import httplib
import sys
import subprocess

def check_webserver(address, port, resource):
    time = subprocess.Popen("date +'%Y-%m-%d %H:%M:%S'", shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    date = time.stdout.read().rstrip()
    #create connection
    if not resource.startswith('/'):
        resource = '/' + resource
    try:
        conn = httplib.HTTPConnection(address, port, timeout=6)
        print 'HTTP connection created successfully'
        #make request
        req = conn.request('GET', resource)
        print 'request for %s successful' % resource
        #get response
        response = conn.getresponse()
        print 'response status: %s' % response.status
    except:
        err_rec=open('/root/wz/python/err_rec.txt', 'a')
        #time = subprocess.Popen("date +'%Y-%m-%d %H:%M:%S'", shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
        #date = time.stdout.read().rstrip()
        err_rec.write('HTTP connection failed: %s:%s %s\n' %(address, port, date))
        err_rec.close()
        print 'HTTP connection failed: %s:%s' % (address, port)
        return False
    finally:
        conn.close()
        print 'HTTP connection closed successfully'
    if response.status in [200, 301]:
        return True
    else:
        err_rec=open('/root/wz/python/err_rec.txt', 'a')
        err_rec.write('HTTP response status: %s:%s %s %s\n' %(address, port, response.status, date))
        err_rec.close()
        
if __name__ == '__main__':
    page_list = open('/root/wz/python/page_list.txt', 'r')
    for line in page_list:
        host_port, res = line.rstrip().split("/")
        host, port = host_port.split(":")
        check_webserver(host, port, resource=res)

说明：脚本中直接是调用linux中的date来记录时间的，这是因为本人对time模块不熟悉，当然
改成用time模块是更好的。 

page_list.txt中放置需要监控的网页(有多少就添加多少)，格式如下：

www.abc.com:80/index.php
www.123.com:81/index.html


 

err_rec.txt是放置错误信息的，格式如下：

HTTP connection failed: 2010-08-26 23:59:30
HTTP response status: 404 2010-08-26 23:59:36

把三个文件放在/root/wz/python中，将page_check_func.py加入crontab中，每2分钟执行一次

整个部署基本上就完成了，脚本写得很粗糙很憋足，当然你可以修改脚本，用飞信连接手机报警，

或者说要监控的网站太多，可以改为多进程或多线程等等，以后有时间我在完善下整个脚本，就可

以放入生产环境中使用了。
