Akvorado vs bwmon

Akvorado is free network-flow software that receives NetFlow, IPFIX, and sFlow records, enriches them, and exposes the results through a web interface. Its inlet forwards incoming flows to Kafka. The outlet parses and augments them before sending data to ClickHouse. SNMP can supply exporter and interface details, while IPinfo or MaxMind can add geographic information. Optional BGP routes received through BMP contribute AS numbers, AS paths, and communities. A Grafana plugin is available, and the inlet, outlet, orchestrator, and console expose HTTP metrics. Written in Go, Akvorado is delivered as a single binary or Docker image, but deployment requires Kafka and ClickHouse. Recommended resources are 8 vCPUs, 100 GB disk, and 16 GB RAM, with AMD64 or ARM64 listed. The console expects an authenticating proxy to provide user headers. Relational data can use SQLite, MySQL, or PostgreSQL; without one, data remains in memory and disappears on restart. Downgrades are unsupported. The license is AGPLv3.

bwmon is a free, self-hosted bandwidth monitor for one Linux host and one network interface. Its dashboard updates receive and transmit rates every second, charts recent traffic, and lists top processes. When traffic passes five times its rolling two-minute average, bwmon records process attribution, all-interface rates, and leading conntrack flows for spike investigation. It retains five-minute samples for six months, with views from one hour to all time, a time-of-week heatmap, and a rate histogram. A banner appears when the rolling five-minute average reaches 40 Mbps; cleared alerts remain in the history table. Installation uses a shell script that sets up the collector, systemd service, cron jobs, and nginx server block; the dashboard defaults to port 8080. It requires Linux kernel 4.0 or later and root access. Debian and Ubuntu use the apt-based installer, while other distributions need manual dependency setup. The project recommends authentication for internet-exposed installations.
