![]() ![]() If you’re seeing only intermittent network issues, try bumping the number of packets up by passing the -c flag with the command. By default, MTR will send 10 packets, which is usually enough to identify issues. The “Snt” column tells you how many packets were sent. The “Loss%” line tells you how many packets were lost in between steps. Each line tells you a single hop your network traffic took between your server and the destination server. The output from MTR contains a few different pieces of information. MTR will try 10 times to reach the site, and collect summary information on the steps it took to get there. To test your connection to Google, for example, you can run: mtr -report Īnd check the output. MTR works by trying to reach the desired site multiple times and summarizing the results in a report. Visit the site, download the executable and you’re good to go. Likewise, on Macs you can just use Homebrew to install: brew install mtrįinally, for Windows users you can use WinMTR, which is built for Windows machines. For example, on Ubuntu the command is just: sudo apt-get install mtr However, in most cases you can install MTR just by using the package manager. The latest instructions for installing MTR are available on the project GitHub page. You’ll need admin access on the machine to install the program, but after that it can run without root permissions Step 1: Install MTR There are versions for Windows and Mac as well. ![]() MTR works on every Linux distribution we tested, including Ubuntu 16 & 18 as well as Debian 8 & 9. MTR lets you identify if and how a breakdown occurs between your server and a server you’re trying to reach. We’ll use a specialized tool called MTR, which is basically a combination of two common network tools: ping, and traceroute. sudo mtr -n -T -c 200, we’re looking at how to diagnose network issues. Below is an example run on the RTMP URL for Mac users. To troubleshoot connectivity issues properly, a TCP-based trace must be run. In addition, you need to run MTR both on the RTMP URL as well as the playback URL, as issues might arise both in the input and output. Using MTR with Live streams is similar to using it to analyze VOD, but a little different because MTR sends ICMP request packets and most internet devices deprioritize ICMP-based trace requests and intentionally throttle ICMP traffic which can create the illusion of packet loss. You can press q at any time to stop MTR.Note the commands listed above the data display, or press h to see all available commands:Ĭopy and paste the information you want from terminal: You should see a display that looks something like this: If you are running WinMTR instead, the only difference is that you will simply enter the domain or IP address that you want to analyze instead running mtr. The instructions below assume you are running MTR as a command line application on Mac OS. The steps below will walk you through the basic installation and use of Wireshark. Now you will be able to run sudo mtr (using sudo is required) # to get the version number - in this case 0.94 - and cd into that directory's /sbin directory To be able to run MTR, you will need to do the following in terminal: Note that Homebrew now installs MTR into a non-path directory (at least on Mac). See How to Run an MTR for information on installing MTR. Submitting MTR reports can help Brightcove Support resolve issues in some cases. It combines the functionality of the ping and traceroute commands. MTR is a popular tool for diagnosing network-related issues.
