My machine use Squid to caching Internet for clients, are there the web tool to see squid log file or manage squid?
Does everybody help me to find this program?
Thanks so much.

What you want is Webmin and Sarg. They can be found here
http://www.webmin.com for management of Squid with a browser
http://sarg.sourceforge.net/sarg.php for monitoring the usage of Squid.

That's great !
Thank for your help.
Which are benefit between them? Please tell me.
Thank you very much.

Webmin is an excellent browser-based administrator for all kinds of things (Apache, Squid, Sendmail, Postfix, etc). It has plug-ins for so many servers it's crazy. It's great for newbie admins as well as making minor changes remotely.

SARG -Squid Analysis Report Generator is used to track where your users go on the web, as well as how much time and bandwidth each person uses. It also tells you what is being downloaded by the users and who is downloading it. We use it with SquidGuard to keep the Pr0n and other such junk off our company network.

Thank for your answer.
After i install SARG, how can i use it as webpage. I also find the document, however it seem not exist. Can you tell me some?

Thanks so much.

Webalizer can analyse squid logs and present it in a graph.

Awstats can analyse squid logs and present it in a graph.

In addition to that squid has its own web interface (additional) which can be used to monitor the cache.

Thank you very much.

Sarg outputs its reports to a directory in your htdocs directory for Apache. That is, if you have Apache installed.
