Trisul is a flexible network traffic monitor. It meters bandwidth usage, counts sessions, and stores raw packets for future analysis. All traffic data is stored in a SQLITE3 database. It communicates with the outside world via the Trisul Remote Protocol (TRP) and via a Ruby-on-rails application called Web-Trisul.
Note: Always download the Featured package. We keep the older packages around in case there is a regression and someone wants access to the previous releases.
