Hello.
I've developed a daemon for monitoring network traffic. It is called yantd (Yet
Another Network Traffic Daemon) and is available at
http://github.com/joeroback/yantd
I would like to see yantd offered in the feeds/packages repository for the
OpenWrt community to use. The git repo contains the OpenWrt build system
Makefile. If a different organization of the repo is more convenient, I am
willing to organize it which way makes it easier for integration in the
packages repo.
The idea came from the ttraff daemon used in the dreaded dd-wrt firmwares. When
I started using OpenWrt I initially started using collectd but found it too
bulky and requires a web GUI to see the graphs.
Additionally, I have one of those ISPs that caps my monthly bandwidth at 250GB.
Collectd was hard to track my usage due to its rolling history.
yantd features:
(*) small on disk and in memory footprint
(*) init.d startup script
(*) UCI configuration, supporting any number of network interfaces
(*) can specify process niceness and I/O niceness via the UCI config
(*) command line interface
A file is used to store traffic data for each month. Each traffic file consists
of a 24 byte header and 16 byte (64-bit RX bytes and 64-bit TX bytes) * number
of days in a month.
Output from the command line interface looks like the following:
r...@router:~# yantd-cli
Usage: yantd-cli [-gkmtv] [-r start-end] <traffic file>
-g Output format Gigabytes
-k Output format Kilobytes
-m Output format Megabytes
-r Only shows days in range (e.g. 3-5 shows 3rd through 5th)
-t Output format Terabytes
-v Show version info
r...@router:~# yantd-cli -m -r 1-15 /mnt/stats/yantd/router-eth1-201007.dat

My current and future plans include:
(*) option to add packet, error traffic data (additional fields from
/proc/net/dev)
(*) optional ncurses interface (to be selected via menuconfig)

Joe Roback
