Network Troubleshooting

Capturing an MTR

In some cases, you may be asked by support to provide an MTR to diagnose potential routing issues between your service and another point on the internet. Below are 2 methods on capturing an MTR, one for Windows and one for each flavour of Linux.

Windows (WinMTR)

  • Download WinMTR
  • Extract the contents of the .zip file to your desktop.
  • Open the WinMTR folder, then open the folder that matches your version of Windows (32-bit or 64-bit) and run WinMTR.exe.
  • Enter the IP address you want to test in the Host field. This will be the IP of the service you're diagnosing.
  • Note: If multiple IPs are listed, run a WinMTR test for each IP address.
  • Click Start, then launch the server you're testing. If no connection issue is found in the first 5 minutes, restart the test.
  • When a connection error occurs, play for at least 5 more minutes, then click Stop in WinMTR.
  • Click “Copy Text to Clipboard”.
  • Reply to your ticket and paste the results within your reply.

Linux

Debian/Ubuntu-based Systems

  • Run the following commands as root to install mtr:
apt-get update
apt-get install -y mtr
  • Run the MTR (replace IP_ADDRESS_HERE with the IP of the service you're diagnosing):
mtr --report -w -z IP_ADDRESS_HERE
  • Select and copy the results from the output, including the fields at the top (Start and HOST) and finishing after the last result displayed.
  • Reply to your ticket and paste the results within your reply.

CentOS/RHEL-based Systems

  • Run the following commands as root to install mtr:
yum update
yum install -y mtr
  • Run the MTR (replace IP_ADDRESS_HERE with the IP of the service you're diagnosing):
mtr --report -w -z IP_ADDRESS_HERE
  • Select and copy the results from the output, including the fields at the top (Start and HOST) and finishing after the last result displayed.
