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 purposely 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  packet
        loss or response time is often an indication of a bad (or simply 
overloaded) link.

        The results are usually reported as round-trip-response times in 
milliseconds and the percentage of packetloss.


I think Windows® has a similar function: mytraceroute.

I like to use the arguments:
-w ; Wide report
-c 9 ; Use 9 iterations in the report
-m # ; trace to a depth of #

Examples:
