MTR, a Linux shell command, combines the functionality of the ‘traceroute’ and ‘ping’ programs in a single network diagnostic tool.
When MTR starts, it investigates the network connection between the host MTR runs on and HOSTNAME (e.g. www.google.com), by sending packets with purposly low TTLs. It continues to send packets with low TTL’s, noting the response time of the transit routers. This allows MTR to print the response percentage and response times of the internet route to the remote host. A sudden increase in packetloss or response time is often an indication of a problematic or saturated link.
Compared to mixing and matching ping and traceroute commands, MTR is a true network diagnostic swiss army knief. For those bound to Windows destkops, Microsofts command link “pathping” is similar to MTR but lacks the real time tracing and statistical data.
