Trisul

Trisul meters bandwidth usage, monitors flows, and stores raw packets for future drilldown 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. What sets Trisul apart from other monitoring tools is its drill-down capabilities for analyzing past events (e.g. "Show me the top hosts using ICMP at 5AM this morning"). Trisul combined with WebTrisul can be used as a Web-based network security monitoring platform. Web Trisul features live SVG charts that allow you to select a time interval and invoke drill-down analysis using the raw traffic data as the source. You can also write tools that communicate with Trisul directly via a secure TLS connection using the Trisul Remote Protocol.
