speedometer

Python script that shows a network traffic graph in the terminal.

TLDR

Show graph for a specific interface

$ speedometer -r [eth0] -t [eth0]
copy

SYNOPSIS

speedometer [options] tap [[-c] tap] ...

DESCRIPTION

Monitor network traffic or speed/progress of a file transfer. At least one tap option (-f, -rx, -tx) must be entered. Option -c starts a new column, otherwise taps are piled vertically.

Note: before you use the program, satrt generating traffic by transferring files in/out e.g. with scp (1) in the network you're measuring.

OPTIONS

-b

Use old blocky display instead of smoothed display even when UTF-8 encoding is detected.

-f filename [size]

Display download speed with progress bar. This option must be used if directly following another file tap without an expected size specified.

-i interval

Interval in seconds. Examples: 5 or 0.25". Default is 1.

-p

Use plain-text display (one tap only).

-rx iface

Display bytes received on network interface.

-tx iface

Display bytes transmitted on network interface.

-z

Report zero size on files that don't exist instead of waiting for them to be created

EXAMPLES

How long it will take for my 38MB transfer to finish?

speedometer favorite_episode.rm $(( 38 * 1024 * 1024 ))

How quickly is another transfer going?

speedometer dl/big.avi

How fast is this LAN?

host-a$ cat /dev/zero | nc -l -p 12345 host-b$ nc host-a 12345 > /dev/null host-b$ speedometer -rx eth0

How fast is the upstream on this ADSL line?

speedometer -tx ppp0

How fast can I write data to my filesystem? (with at least 1GB free)

dd bs=1000000 count=1000 if=/dev/zero of=bigfile & speedometer bigfile
