How long does it take for MTR to resolve a problem?
Most issues detectable by MTR will resolve themselves within a few hours. If a problem is significant, you can often rely on your service provider to detect and resolve the issue. Chances are, if you noticed it, then the provider’s monitoring team is already working to resolve it if it is a local issue.
How often does MTR send a trace report?
MTR sends a series of trace probes once a second by default, so a report should complete in just over a number of seconds equal to your count number (200 seconds in the above example). . There are several other options you might find useful while using MTR.
What is the time to live value of MTR?
MTR generates an ICMP Echo Request packet destined for the target IP/hostname of your mtr command. The first packet will have a time-to-live (TTL) value of 1.
When to take the worst time column in MTR?
If the worst time column for each subsequent hop showed the same or greater time, then we could take that result of an incident pointing to potential latency issues. Note, in contrast, the average time column, particularly between hops 6 and 7.

What do the numbers on the MTR mean?
The numbered lines on the left-hand side of the screen refer to hops. The names to the right of the numbers are the names of the hosts being contacted. The Loss % column shows you packet loss. The Snt column shows you the number of packets sent. The Last, Avg, Best and Worst all measure latency in ms.
Why do you need MTR and traceroute?
With Traceroute, you have to update scans manually to measure how a network’s performance changes over time. In contrast, you can run MTR and your information will be connected until you say stop. Being able to monitor the change in network performance over time helps when it comes to troubleshooting.
When do you need to trust the MTR?
If one hop has a high packet loss but the other surrounding hops are at 0% then it is almost certain that MTR is being limited. As a general rule, if you see lots of different rates of packet loss being reported it is advisable to trust the later hops.
