What is this?
=============
Bandwidth Monitor NG is a small and simple console-based live network and disk
io bandwidth monitor for Linux, BSD, Solaris, Mac OS X and others.
Short list of features:
- supports /proc/net/dev, netstat, getifaddr, sysctl, kstat, /proc/diskstats
/proc/partitions, IOKit, devstat and libstatgrab
- unlimited number of interfaces/devices supported
- interfaces/devices are added or removed dynamically from list
- white-/blacklist of interfaces/devices
- output of KB/s, Kb/s, packets, errors, average, max and total sum
- output in curses, plain console, CSV or HTML
- configfile
This was influenced by the old bwm util written by written by Barney
(barney@freewill.tzo.com) which had some issues with faster interfaces and
was very simple. Since i had almost all code done anyway for other projects,
i decided to create my own version.
I actually dont know if netstat input is usefull at all. I saw this elsewhere,
so i added it. Its target is "netstat 1.42 (2001-04-15)" linux or
Free/Open/NetBSD. If there are other formats i would be happy to add them.
For info about libstatgrab please refer to http://www.i-scream.org/libstatgrab/

INSTALL
=======
For detailed decription please read INSTALL
./configure --help for a list of options
./configure
make
to install use as root:
make install
WIN32
=====
To compile the Windows version in Linux (debian):
./configure --with-win32 --without-procnetdev --without-diskstats --without-curses --without-netstatlinux --build i686-pc-linux-gnu --host i586-mingw32msvc
make
get ansi.sys for better output: http://en.wikipedia.org/wiki/ANSI.SYS
Specs
=====
csv output format:
Type rate:
unix timestamp;iface_name;bytes_out/s;bytes_in/s;bytes_total/s;bytes_in;bytes_out;packets_out/s;packets_in/s;packets_total/s;packets_in;packets_out;errors_out/s;errors_in/s;errors_in;errors_out\n
Type svg, sum, max:
unix timestamp;iface_name;bytes_out;bytes_in;bytes_total;packets_out;packets_in;packets_total;errors_out;errors_in\n
Use --count 0 to skip the all zero output after start.
html output format:
edit the bwm-ng.css to modify the output. Please note the htmlrefresh only
modifies the META refresh, you maybe wanna sync --timeout and --htmlrefresh
USAGE
=====
USAGE: bwm-ng [OPTION] ... [CONFIGFILE]
Please read the manpage or `bwm-ng -h` for a list and explanation of options.
Keybindings (curses only):
'h' show help
'q' exit
'+' increases timeout by 100ms
'-' decreases timeout by 100ms
'k','d' switch KB and auto assign Byte/KB/MB/GB
'a' cycle: show all interfaces, only those which are up,
only up and not hidden
's' sum hidden ifaces to total aswell or not
'n' cycle: input methods
'u' cycle: bytes,bits,packets,errors
't' cycle: current rate, max, sum since start, average for last 30 sec
Configfile
==========
either via cmdline or /etc/bwm-ng.conf or ~/.bwm-ng.conf
it consists of:
longoption=value
with 1 or 0 as values for keys without a value in cmdline options.
For more help take a look at bwm-ng.conf-example
Misc
====
Bugs/Known Problems:
- curses output coredumps on netbsd 1.6.1 (maybe others) with unknown TERM
set and configfile support compiled in
- no other yet, wow ;) (please report if you found one)
Todo:
- Docs
- checking options to be valid
- mysql output (ipac-ng compatible)
- setting which stats to output for csv/sql
- distributed gathering of stats (client/server)
- whatever you can think of
