"yaala" parses logfiles and generates very detailed statistics in HTML format. The information one will get can be selected by using SQL-like expressions, which provide filtering with relational operators (like equal, greater than, less than) as well as regular expressions. It includes input parsers for the Common Log Format (e.g. Apache's access logs), NCSA logs (e.g. Apache's combined logs), Squid access logs, the xferlog format (used by FTP daemons), bind9's query logs, and postfix entries in the maillog.
