MTR represents an evolution of the `traceroute` command by providing a greater data sample, as if augmenting `traceroute` with `ping` output. This document provides an in depth overview of MTR, the data it generates, and how to interpret and draw conclusions based on the data provided by it. -For a basic overview of network diagnostic techniques, see our introduction to [network diagnostics](/docs/using-linux/administration-basics/#network-diagnostics). If you are having general issues with your system, read our overview of general [system diagnostics](/docs/using-linux/administration-basics/#system-diagnostics). - ## Network Diagnostics Background -For a simple overview, check [this document about network diagnostics](network-diagnostics). Networking diagnostic tools including `ping`, `traceroute`, and `mtr` use Internet Control Message Protocol (ICMP) packets to test contention and traffic between two points on the Internet. When a user pings a host on the Internet, a series of ICMP packets are sent to the host, which responds by sending packets in return. The user's client is then able to compute the round trip time between two points on the Internet. In contrast, tools such as traceroute and MTR send ICMP packets with incrementally increasing TTLs in order to view the route or series of hops that the packet makes between the origin and its destination. The TTL, or time to live, controls how many hops a packet will make before "dying" and returning to the host. By sending a series of packets and causing them to return after one hop, then two, then three, MTR is able to assemble the route that traffic takes between hosts on the Internet. @@ -342,4 +339,4 @@ A majority of routing issues displayed by MTR reports are temporary. Most issues While routing errors and issues account for a percentage of network-related slowness, they are by no means the only cause of degraded performance. Network congestion, particularly over long distances during peak times, can become severe. Trans-Atlantic and trans-Pacific traffic can be quite variable and are subject to general network congestion. In these cases, it is recommended that you position hosts and resources as geographically close to their targeted audience as possible. -If you are experiencing connectivity issues and are unable to interpret your MTR report, open a support ticket.
