In this tutorial, I will take you through 7 Simple Steps to Install MTR on Linux(RHEL/CentOS 7/8). MTR is an open source command line Network diagnostic tool which has the functionality of both traceroute and ping command. It implements the functionality of both traceroute and ping command and has many added features over these commands.
While using MTR tool for tracing the path of destination server you can see lot of other useful statistics for each of the hops as compared to traditional traceroute command that you use. You can see important information like packet loss percentage, av. response time etc. Hence it is a very important tool to troubleshoot and debug any network issues between source and destination.
a) You require a running RHEL/CentOS 7/8 Server.
b) You should have yum installed in your Server.
c) You should have root or sudo access to run Privileged commands on your Server.
Before going through the steps to install MTR on RHEL/CentOS 7/8, it is always recommended to update your Server first by using yum update -y command.
[root@localhost ~]# yum update -y

It’s usage is pretty much same as traceroute in Linux. You can simply run mtr <domain_name> or mtr <ip_address> command to trace the path of a URL based on domain name or IP Address. For example here we are tracing the path of google.com using mtr google.com command as shown below.
[root@localhost ~]# mtr google.com
