How to diagnose network problems with MTR
MTR is a powerful network diagnostic tool that allows system administrators to diagnose and locate network errors and provide network status reports to upstream providers. 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.
