Traditionally the traceroute (print the route packets take to network host) and ping (send ICMP ECHO_REQUEST to network hosts) programs are used as diagnostic tool to solve and isolate networking errors. It may take some time to use both tools to diagnose network issues. However, you can use the mtr program instead of ping and traceroute. It is a network diagnostic tool and it is the combination of traceroute and ping programs (in terms of functionality) and works as a single network diagnostic tool.
Once mtr invoked it starts investigates the network connection between the hosts (workstation) mtr runs on and HOSTNAME by sending packets with purposely low TTLs (time to live). It will continue 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.
During this run if you notice a sudden increase in packet-loss or response time is an indication of overloaded link or a bad link.
