"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.
NISCA (Network Interface Statistics Collection Agent) is a more flexible PHP4-based MRTG replacement. It supports both SNMP and reading localhost's /proc/net/dev device file directly for statistics gathering. It uses MySQL to store collected data in, and stores statistics for bytes transferred, packets transferred, transfer errors, and dropped packets separated into a per interface incoming and outgoing set. It generates both graphs and a textual report table using the data from any timeframe contained in the database. The entire package runs using PHP4; it uses the CGI binary version of PHP for stats collection (running in the background as a "daemon") and either the CGI or Apache module versions to generate the GUI form and reports. It can also import existing MRTG logfiles.
proxy-report.pl generates a list of requested server addresses (simplified URLs) from your Squid proxy server log files. Requests for each URL are summarized on a per day basis. This script can generate reports based on the IP of the user. It also automatically handles gzipped files. URL exclusion patterns are supported. A sample report is available on the home page.
