9.2 MTR results analysis
Posted by Evita Lin on 27 May 2016 02:19 PM
Analyzing WinMTR / MTR output, the most important is: packet loss and lateancy.
First of all, you need to pay attention on packet loss.
When you find packet loss on any nodes, it might mean this particular routing node may has some problem.
However, some service providers have restrict to WINMTR / MTR tool sending an ICMP transmission.
It causes illusion on packet loss but actually there is no packet loss.
it is just restrict for ICMP, not actual packet loss.
In this case, the loss from the first hop to the second one is may due to the routing restrict to ICMP.
Another example for comparison:
In this case, 60% packet loss between the third and fourth one, then you can assume
Based on two different loss results, we always take the packet loss rate of the last-hop as actual rate.
Some packet loss may occur on returned transmission. Sometimes packets can reach the destination correctly

Hostname: each node to the destination server host name or IP to go through.
Nr: After the number of nodes
Loss%: ping packet reply to the percentage of failures;
Sent: The number of packets have been transmitted.
Recv: the number of packets successfully received.
Best: minimum response time.
Avrg: the average response time.
Worst: the maximum response time.
Last: The last packet response time.
