We do this because internet traffic doesn’t always take the same path in both directions. And then after that, you will run an MTR test from the server while testing against the end user’s “local IP”. This means the end user will run MTR using the “target IP” (server IP) to run a test from their own computer. Once you know your local IP and the target IP, it is necessary to run MTR in “both directions” to best identify the source of any network issues. We will call the server IP the “target” IP. It is also critical to know the IP address of the server that is having problems. If you do not know your local IP, you can find it from an IP website such as. Therefore, if an end user is having trouble reaching your network, it is critical to know the IP address of that end user. Typically, performance may suffer between one source and one destination without impacting other destinations. The interval (time between iterations) should be 0.5 seconds or slower.Ī network problem does not exist for all parts of the internet at once.Run MTR with the –no-dns option enabled.Run the MTR test in both directions (from the client to the server, and from the server to the client).To get useful MTR results, follow these important tips: As well, this allows them to bring the issue to the attention of the network in question, asking them to fix the problem. A generic complaint of “the network is not good” does nothing to help narrow down which router is having a problem and therefore provides no ability to route around the problem network hop.īy knowing the hop where packet loss begins, a network operator can adjust their routing to avoid the troublesome network hop. This allows MTR to provide a more in-depth report of the connection quality than a standard traceroute.įrom an end user perspective, the biggest reason to use an MTR, is that without the MTR results, their hosting provider has no ability to determine if there is a network problem and no ability to solve it. As a result, MTR can be used to determine if there is packet loss on a particular route, and which network hop that packet loss begins. Packet loss as low as 0.2% can cause performance problems, and so testing a link using an MTR with 1,000 or more iterations is necessary to find this small amount of packet loss. The main difference from a traceroute is that MTR tests each hop many times, whereas a traceroute by default only tests each hop 3 times.īecause an MTR tests each hop many times, it is possible to identify the source of small amounts of packet loss. Both tools help you understand if a packet is taking a sub-optimal path to reach its destination, such as, going from Hong Kong to Los Angeles to Singapore, instead of directly from Hong Kong to Singapore. Both MTR and traceroute calculates the route a packet takes and shows the user the amount of time taken for the packet to traverse each hop. To summarize, the MTR diagnostic tool is mainly used to assist in identifying where internet connections are failing, and in the process, help identify what is causing network performance to suffer.Ī standard traceroute is primarily used to understand the routing within a network. Once polled, an MTR reports the quality of connections in the format of a table. It has replaced the standard Traceroute as a go-to tool, mainly used to poll remote servers with a hop-by-hop analysis similar to a standard traceroute. MTR or MyTraceRoute is one of the most popular diagnostic resources available at the moment.
