Two examples of a typical traffic display. nwload adapts to any window size, can be resized while it is running and always uses available space to yield full resolution. | |

| nwload's main menu. nwload differs from other similar utilities in that it is designed as a measurement tool, i.e. it tries to be as exact as is possible in a non-realtime environment. It doesn't autoscale to yield curves which look impressive but can't be interpreted, but offers various options and submenus to set X and Y axis scaling. |

One of nwload's submenus. This one is for setting the horizontal grid lines (Y grid spacing). | |
nwload can be used to monitor any networking
device in a GNU/Linux environment. Y axis display (traffic
values) will be exact within the limits of the kernel's counter
under any load circumstances; X axis (time) display will be exact
as long as rescheduling delays its execution for no more than 2
sampling intervals (e.g. 2 sec for a typical application).
nwload allows you to save its settings to a
file from where they are reloaded on startup. You can have a look
at its man page for a detailed
description. There is also an INSTALL file if you have
questions about installation details. Generally, there is nothing
specific here: Make sure that you have Python and Tkinter (which
is a part of Python) installed, then simply type "make
install".
nwload is available here as a gzipped tar file. Current version is v0.2e. There are currently no updates planned - there are no topics on the todo and wish lists -, but I'll continue to support it as long as traffic suggests that there is some interest in it (and probably for some amount of time after that).
