BBclone is a PHP Web counter on steroids which displays individual logs as well as aggregated data. It is a clone of Big Brother webstats, except that it is written in PHP and it relies only on flat files (no database needed). BBclone enables any Web site administrator to have a very precise view of who visit the website: OS, browser, date, referring page etc. Main features include reload resistance, hostname resolution, proxy workaround, and blacklist.
phpOpenTracker is a framework solution for the analysis of Web site traffic and visitor behaviour. It features a logging engine that, either invoked as a Web bug by an HTML image tag or embedded with two lines of code into your PHP application, logs each request to a Web site into a database. One installation can track an arbitrary number of Web sites. Through its API, you can easily access the gathered data and perform complex operations on it (for instance, the analysis of your visitors' click paths).
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.
IPTables log analyzer displays Linux 2.4 iptables logs (rejected, accepted, and masqueraded packets) in a nice HTML page. The reports it produces are easy to read and understand, reducing the manual analysis time. They contain statistics on packets and links to more detailed information on a given host, port, or domain.
