Web server log analyzer?

Question

Journaling

Google gives me various tools for analyzing statistics. But I need something else.
You need to be able to view the log by mask. Filter by date eg. By request type, by IP. Filter by regularity.

Answer 1

So filter by regular expression, but by what you want, what's the problem? sed, awk, Perl, Python, PHP, any other script of 1 or more lines. It is not very clear how "statistics analyzer" relates to a banal filter.
Perl modules Logfile::Access , HTTPD::Log::Filter , Parse::AccessLogEntry
chapter "Parsing Web Access Logs" from the book "Perl for Web Site Management" on parsing with regexps

Answer 2

sawmill can do most of your wishlist.

Answer 3

MacOS has a built-in log viewer with a graphical interface and a filter.
