bmon vs Intermapper

bmon is a free bandwidth monitor and rate estimator for Linux and macOS. It captures networking statistics for monitoring and debugging, presenting them through an interactive curses interface or programmable text output for scripts. The 5.0 release notes describe graph rendering with Braille cells, JSON output, traffic-control ingress and egress display filters, and IPv4 and IPv6 addresses in additional information. Installation guidance covers Fedora and CentOS 7 packages, Debian or Ubuntu and CentOS 6 builds, and macOS installation through Homebrew or source compilation. Release notes also mention CI builds for Linux, macOS, and FreeBSD, with fixes for FreeBSD, DragonFly BSD, and OpenBSD builds. The repository lists MIT and BSD license files. bmon is maintained by tgraf and hosted on GitHub Pages. Its free plan costs nothing.

Intermapper helps IT teams discover network devices and servers, map their relationships, monitor health and performance, and receive alerts when conditions change. Its live maps show infrastructure, dependencies, device status, and network connections. Auto-discovery identifies devices and helps keep the network view current as environments change. Flows Insight analyzes NetFlow, sFlow, jFlow, and cFlow data to show traffic patterns, utilization, and top talkers. Advanced Reporting provides dashboards and automated reports for uptime, service health, SLA performance, and infrastructure trends. Intermapper supports SNMPv3, includes built-in probes, and allows custom probes. APIs and add-ons, including the Intermapper App for Splunk, can complement other tools. Remote access supports SSL and username/password or network-address authentication. A fully functional 30-day trial is available, but continuing afterward requires a purchase. Licensing is based on monitored devices, with subscription or perpetual options starting at 10 devices and extending to unlimited; pricing is by custom quote. Paid licenses include 24/7 technical support according to the upgrade page.
