superseriousstats is a small and efficient program for creating a Web page with statistics from various types of IRC logs. It keeps track of its parse history and only processes new activity before storing any accumulated data in a SQLite or MySQL database. It is suitable for high volume IRC channels and large log archives, and is relatively easy to integrate with IRC services (e.g. bots) that interact with the database and provide last seen information and many other statistics directly in your channel.
ida-syslog is a Web-based viewer for syslog data. It requires syslog data in a MySQL database. It uses AJAX and is based on jQuery and PHP. It is intended for use with rsyslog-mysql, but can be adapted to any table format via the config file. It has a fast UI with no page reloads, and can save search settings as templates for easy reuse. Tail mode and auto-loading of older entries when scrolling down. Fixes for use with Windows-Syslog-Tools (NTSyslog2, Snare).
