HOW TO GET STATISTICS FROM THE WWW LOGFILES

First of all you have to login wwwlab in order to follow these steps:
• The WWW log files are accesible from wwwlab in the directory: /W3dir/Logfiles. During one month we keep a separated daily log file which name is: httpd.YYMMDD.log where YY are two last digits of the year, MM the month and DD the day.

  So, for example the log file for the day 19/9/94 will be: /W3dir/Logfiles/httpd.940919.log

• If you want statistics only refered to "your part of the server www", let's call it "YourWeb" do the following:
  Normally you have a directory asigned in www called /W3dir/YourWeb and the URLs to your pages all start with http://www.cern.ch/YourWeb. So you can create "yourWebLogFile" as follows:

     grep "\/YourWeb" /W3dir/Logfiles/httpd.YYMMDD.log > /home/user/yourWebLogFile.log 
  
  

  Use this "/home/user/yourWebLogFile.log" in point 2 as log file to analyze. This will make you to get the results much faster as the log file used is much smaller.

• You can specify what kind of statistics you want using this Form to get statistics and filling the fields in this way:
  1. Which log file do you want to analyze? Specify the complete path of "yourWebLogFile.log" as the example above
  2. If you want a complete report, choose: Would you like all the reports by default?
  3. The rest of the options choose whatever you want
  4. It will take several minutes to get the results
  5. Important!! If you get an ERROR message it may be because of
     • some errors in the format of the log file, or
     • the log file is too large and the timeout for scripts to give an answer is not enough for it. In this case you should use "yourWebLogFile.log" as log file to analyze as it's much smaller.
• If you want statistics for more than one day, a week or so, you just have to append ths daily log files you need and put it in a file somewhere in your home directory . But ALWAYS remember to remove that file after using it for the statistics as they are quite large files !!

  Example:
  
  To append the files 940101, 940102 and 940103:
  
  
  prompt> cat httpd.940101.log > /home/user/tmp.log
  prompt> cat httpd.940102.log >> /home/user/tmp.log
  prompt> cat httpd.940103.log >> /home/user/tmp.log
  	.....
  Filling the form specifying /home/user/tmp.log as the log file to analyze.
  	....
  prompt> rm /home/user/tmp.log
  

• The program that generates the statistics is getstats . Please, don't install it in your local space as it is already in www. If you want to use it without the form above, ask www.support@cern.ch
