The MTR (My traceroute) is a network diagnostic tool that incorporates pings and traceroute into a single program. The MTR provides two interfaces: a ncurses interface that is useful for using MTR from a Telnet session, and a GTK + interface for X (provided in the MTR-GTK package).

MTR use

1. MTR Command line tools

MTR is easy to use, please refer to the man page of MTR for detailed usage.

[Email protected] ~]# Mtr–help

usage:mtr [-hvrctglspni46] [help] [–version] [–report]

[–report-cycles=count] [–curses] [–GTK]

[–raw] [–split] [–no-dns] [–address Interface]

[–psize=bytes/-s bytes]

[–interval=seconds] HOSTNAME [PacketSize]

The main parameters are explained as follows:

–report trace results in report mode output

–report-cycles=count defines the number of traces, the default is 16

–raw to output the result in the original format

–split the results of each trace separately, not like –report, to count the entire result

–no-dns only displays IP addresses, does not resolve host names corresponding to IP addresses

–psize=bytes/-s bytes defines the size of the packet, in bytes


Mtr-h provide help commands

Mtr-v displaying the version information of the MTR

Mtr-r reported mode display

Mtr-s used to specify the size of the ping packet

Mtr-nno-dns IP address does not do domain name resolution

Mtr-a to set the IP address of the sending packet this is useful for a host by multiple IP addresses

Mtr-i Use this parameter to set the requirement between ICMP returns by default is 1 seconds

Mtr-4ipv4

Mtr-6ipv6

As a result, you can visually see the minimum/maximum time and standard deviation of packet loss and ping commands from my host to the routed nodes that pass through and to each node.

Report Description:

First column: The IP address and the native domain name are displayed, which is like tracert

Second column: Snt:10 sets the number of packets sent per second, the default value is 10 can be specified by the parameter-C.
Where-C is the description:--report-cycles COUNT

Column Three: is the packet loss rate for each corresponding IP displayed

Fourth column: The most recent return delay shown

Fifth column: Is the average this should be the mean time delay for sending ping packets

The Sixth column: is the best or the shortest delay

The seventh column: The worst or the most frequent delay

Eighth column: is the standard deviation
