Estoy subscrito al RSS de Planet Ubuntu[1] y por esa vía me llegó un
post[2] bien interesante con esta herramienta que desconocía por
completo.

NAME
       mtr - a network diagnostic tool

SYNOPSIS
       mtr    [-hvrctglspni46]    [--help]   [--version]   [--report]
 [--report-cycles COUNT]   [--curses]   [--split]   [--raw]
[--no-dns]   [--gtk]
       [--address IP.ADD.RE.SS] [--interval SECONDS] [--psize BYTES |
-s BYTES] HOSTNAME [PACKETSIZE]

DESCRIPTION
       mtr combines the functionality of the traceroute and ping
programs in a single network diagnostic tool.

       As mtr starts, it investigates the network connection between
the host mtr runs on and HOSTNAME.  by sending packets with purposly
low  TTLs.  It
       continues to send packets with low TTL, noting the response
time of the intervening routers.  This allows mtr to print the
response percentage and
       response times of the internet route to HOSTNAME.  A sudden
increase in packetloss or response time is often an indication of  a
bad  (or  simply
       overloaded) link.
