I’ve been doing something similar at home for years. An OpenBSD box at the egress point exports IPFIX data to nfdump and I designed custom charts for myself using the legacy dygraphs. IPFIX plus nfdump is wonderful as I can quickly use a tcpdump-like interface to very quickly search against data from months ago and the dygraphs charting allows me to easily see traffic patterns with the ability to quickly zoom in.
