How to collect statistics on the web server?

Question

PHP

Here I have a web server with several sites on it. I would like to have visit statistics for everyone, who requested which script, time on the site, from which site they went, for which search word, etc.
Maybe there is some suitable php script, for this or some kind of software?

Why load your server with this)

Answer 2

You can use log analyzers. For example, the most popular Webalizer and AWStats:
www.webalizer.org
www.awstats.org
However, you need to understand that such an analyzer creates an additional load on the server at the time of calculating the logs (sometimes significant if the logs are large). You also need to write logs in standard formats or change the log format settings in the analyzer if your web server writes logs in its own format.
