About the MTR Report

MTR combines traceroute and ping: it sends ten ICMP echo probes to every hop on the path and reports, per hop, how many were lost and how the round-trip time varied. That separates a router that is merely slow to answer from a path that really loses traffic, which is the evidence a network operator asks for.

• Loss, last, best, average and worst time and StDev for every hop
• Each hop's name and network (AS number)
• Ten probes a hop in about fifteen seconds, from the OpenVibe server

Frequently asked questions

Why is MTR better than traceroute for support tickets?

It samples repeatedly, so it distinguishes a genuinely lossy hop from a single dropped probe. That is the evidence a network operator needs.

A middle hop shows loss but the destination shows none. Is something wrong?

Usually not. Routers limit how often they answer probes addressed to themselves while forwarding traffic normally. Loss that starts at a hop and carries on to every hop after it, including the destination, is real loss.
