It detects hosts with abnormal traffic volumes and can notify operators, run scripts, or trigger BGP-based mitigation. ### Project history The public FastNetMon repository dates to 2013 and the official documentation site has carried Community Edition documentation since 2016. The README now presents the open Community Edition alongside FastNetMon Advanced, a commercial edition from FastNetMon LTD. Technically, the project grew around packet and flow ingestion rather than web-service monitoring: the README lists NetFlow v5/v9, IPFIX, sFlow v5, PCAP, AF_PACKET, AF_XDP, Netmap, and older PF_RING support. That breadth explains why the package has daemon, client, API-client, capture-backend, and router-integration concerns. ### Adoption history FastNetMon is aimed at network operators, hosting providers, and other teams that need fast traffic anomaly detection close to routers or mirrors. Its official support surfaces include a mailing list, Slack, IRC, Telegram, and Discord, which is a strong signal of an operator community around the tool. The README points to Linux installation instructions, macOS installation through Homebrew, and a FreeBSD port, while its Repology badge tracks distribution packaging. The Community Edition release stream continued through the 1.2.x series, including 1.2.8 in 2024 and 1.2.9 in 2026. ### How it is used FastNetMon is configured as a sensor for local networks and thresholds. It watches packets, bytes, or flows per second, compares them with configured limits, and then executes configured actions such as notifications, callback scripts, ExaBGP or GoBGP announcements, and metric export. The default Unix-style configuration path is /etc/fastnetmon.conf, with related network-list paths such as /etc/networks_list and /etc/networks_whitelist shown in the distributed sample configuration. It has no documented user credential file for the package itself. ### Why package nerds care FastNetMon is interesting to package maintainers because it is a real network daemon with a CLI client surface, fast-path packet capture integrations, BGP/router integrations, telemetry options, and a long-lived open/commercial split. Packaging it is less about installing one binary and more about preserving operational defaults. ### Timeline - 2013: The public GitHub repository is created. - 2016: The official Community Edition documentation page is published. - 2022: FastNetMon Community 1.2.2 is released. - 2024: FastNetMon Community 1.2.8 is released. - 2026: FastNetMon Community 1.2.9 is released. ### Related projects - FastNetMon commonly integrates with ExaBGP or GoBGP for BGP announcements and with systems such as Prometheus, Kafka, ClickHouse, InfluxDB, Graphite, Redis, MongoDB-compatible stores, and router vendors documented by the project. ### Sources - - - - - ## Security Notes broad file, network, media, or database tool signal. formula declares a Homebrew service. - **Geiger risk:** orange / medium - broad file, network, media, or database tool signal - formula declares a Homebrew service ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
