The record

Purpose: OphanimFlow collects, classifies and preprocesses NetFlow, IPFIX and sFlow data to graph network bandwidth per host and provide traffic accounting.
Collectors: NetFlow/IPFIX and sFlow collectors can run simultaneously and share network configuration and database tables.
Web interface: The setup instructions say a web interface lets users configure networks and start using OphanimFlow.
Supported setup systems: The README provides batch setup instructions for FreeBSD 14.4/15.0/15.1 and Debian 13.0 trixie.
Graph API: The REST API can return traffic graphs as PNG images, with options for IP address, direction, time period and image dimensions.
Traffic summary API: The gettraff endpoint returns upload and download byte totals for all hosts or a specified IP, with optional year and month parameters.
External use: The README says the REST API can provide preprocessed data and graphs for use in external apps.
API access: The README states API endpoints are accessible without authorization and documents an ENDPOINTS_HOSTS setting to restrict which host IPs can receive data.
Initial credentials: The setup instructions give the default login as admin and password as demo, and advise changing the password in user profile settings.
Data retention: Since release 0.0.5, OphanimFlow automatically rotates and flushes old data to reserve storage space, set to 10% by default.
Collector defaults: The documented default NetFlow UDP port is 42112, the sFlow port is 6343, and the sampling rate is 100.
License: The GitHub repository identifies the project license as GPL-3.0.
Intended use: The repository topics include ISP management, bandwidth monitoring, traffic analysis and traffic visualization.
