BandwidthD tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization. Charts are built by individual IPs. Color Codes HTTP, TCP,UDP, ICMP, VPN, P2P, etc.

This is the PostgreSQL version of bandwidthd which supports multiple sensors and uses a dynamic (php-based) web interface. If you don't need these features then using the package bandwidthd is suggested.
