How to analyze Apache access.log with AWStats?

When i use VirtualSever in which provide the awstats report for administrator to help analyze the webserver`s visit status.In my case , I want a single static html file , easily to share πŸ™‚

First of all .you must change you awstats.model.conf correctly!

In my case , i change this.

# i change to 4 default is 1

# change the path to you access.log file full path!

Then you can run the command below to generate the html report file!

$ cd awstats-7.7\wwwroot\cgi-bin
$ perl -config=model -output -staticlink >> youserver.html

When you access.log file include long duration of can use sed command to extract the line you want to analyze!

$ sed -n '[start line number],[end line number]p' access.log >> access_sed.log


Some images in the static html can`t show , so i will figure it out later.
