Simon, Good on you! I installed Octomon yesterday. Fantastic tool, thanks for giving back to the community. Cheers, Harry On Sun, Oct 25, 2026 at 10:40 AM Simon Thorpe via NANOG < nanog@lists.nanog.org> wrote:
Hi all,
I'm Simon and I work at Cloudflare. I have leaned on the NANOG archives for years when chasing odd behaviour between a host and the wider internet, so I wanted to give something back and share a tool I built, in case it is useful to anyone here or to the people you support.
octomon is an open-source terminal dashboard for the end-host view of a connection: per-target latency, loss and jitter, per-process and per-remote bandwidth, Wi-Fi signal, resolver health, path MTU, clock offset, and the ISP path from traceroute.
I was sick of running a load of separate tools and scripts, piecing together the information to determine what was going on with my Internet connectivity. I also wanted to learn Rust, so this was a chance to tidy up all the scripts I've built over the past 30 years into a single cli tool for helping me diagnose my device to Internet connectivity.
Quick video of me walking through it here... https://www.youtube.com/watch?v=ECwBaSvUwfk
Thanks,
Simon _______________________________________________ NANOG mailing list
