mtr

mtr combines the functions of traceroute and ping programs and is a simple network diagnostic tool

Supplementary instructions

Used to investigate the network connection between the host where mtr is running and a user-specified target host. After determining the address of each network hop between machines, it sends a series of ICMP ECHO requests to each machine to determine the quality of the link to each machine. In the process, it prints operational statistics for each machine.

Debian distribution has built-in mtr, other distributions can install it by themselves and support mainstream operating systems. You can visit its official website for details.
