NetFlow Dashboard is an open-source project that provides a web interface for "near real-time" analysis of NetFlow traffic. It's designed to aggregate network accounting data in such a way as to allow easy diagnosis of traffic anomalies. It is not intended to replace off-the-shelf utilities that measure bandwidth usage. Those are typically SNMP-based and focus on "snapshotting" network throughput without giving a detailed look into specific TCP/IP connections or application usage. This is where NetFlow excels.
