![]() If the growth is proportional and does not present significant jumps, this means that there are no problems on the network. Normally the latency increases proportionally to the test execution time. The latency data is shown in the last five columns of the report (the second column shows the progressive number of the ICMP packets sent). These data are very often observable but do not indicate malfunctions or network problems.Ī significant loss of data from hop 8 to 13 indicates a serious connection problem and certainly deserves further investigation. It is generally observed at the ISP address and is caused by bandwidth limits set by the ISP itself or by the fact that the router CPU is busy.īandwidth of our ISP causes, on the Mtr report, the presence of a small packet loss in the first hops. If in the report we find a single Hop with a high percentage of lost packets this certainly does not represent a network problem. On the first column of the report, for each Hop, the percentage of packages that have not reached the destination host is indicated. The Hops between these two groups represent the internet network between the two networks analyzed. Furthermore, the first Hops shown in the report generally belong to your ISP (Internet Services Provider) while the last Hop belong to the ISP of the destination Host. ![]() One realizes that the results are very often different in one direction or another. Considering that a single test with Mtr is unidirectional, it would be advisable to trace in both directions. The MTR output shows data for two sectors of analysis: lost packets and latency. Interpretation of MTR results Basic concepts:Ī reliable test with Mtr should last at least ten minutes. The result is similar to that reported for Linux Based Operating Systems. Open a terminal and execute the command “sudo mtr ”.You can download the Mtr package from Rudix, a platform that offers several utilities for MAC systems and generally for Linux Based systems. Insert an IP address or a domain name in the Host field and click on “Start”.The result is generally a data report like the one below: Installation and use of MTR on Linuxįor operating systems based on Redhat, download MTR as follows:įor Debian based operating systems, download MTR with the following command: Mtr, after having determined every single Hop address (Hop are the single nodes (router or other devices) that are located between the source and destination hosts), sends to each single node a series of ICMP ECHO commands so as to being able to check the quality of the connection between the computer of the source and the destination computer. Generally a test is carried out between a Host, where Mtr is installed, and a Destination Host specified by the user. In this article we will see how to install MTR Traceroute and how to interpret the returned data. My Traceroute (mtr), combines the features of Ping and Traceroute software in a single application useful for analyzing the quality and performance of network traffic.
