Real-time bandwidth use

[gwl]

Is is possible to get a value of the actual download/upload rate in kb/s?
(via telnet)

thanks,

Ik now that you can get upload values by doing

wshaper status eth1

if you use Wondershaper.

There are other users who posted traffic accounting scripts, you might want to check them out.

See https://wl500g.info/showthread.php?t=666 for iptraf or use inclused executable of vnstat, use it with vnstat -tr to see traffic in last 5 seconds. You need to make a directory /var/lib/vnstat. If you want to use the database options, make a symbolic link to a usb disk. In iptraf you can use filters to select specific traffic on a specfic interface. Vnstat gives all traffic on an interface.

This is my solution...
Still figuring out how to use crond to take "snapshots"...

cat /proc/net/dev | grep ":" | sed -re 's/ +/ /g' | sed -re 's/ //' | sed -re 's/: /:/' | sed -re 's/ .+//'

cat /proc/net/dev | grep ":" | sed -re 's/ +/ /g' | sed -re 's/ //' | sed -re 's/: /:/' | sed -re 's/ .+//'

Nice think, it works.
Still i´m not sure what is the best solution from all posted ones here in the Forum. darkstat is such a nice think but the output tends to me from meaningless to uncorrect. What is the "golden way" to measure throughput under linux. DevFs, a filter rule, one of the special programs, the ifconfig value ... ?

In general, some formated value readable from the Web IF like currend / hour / day would be nice. For my curiosity, but maybe very interresting for users of volume flatrates.

Search the forums for ltraf. It's small program that does only that, realtime bandwith monitor. Hopefully, if you are lucky , you can also filter the bandwith with bpf filters.

cat /proc/net/dev | grep ":" | sed -re 's/ +/ /g' | sed -re 's/ //' | sed -re 's/: /:/' | sed -re 's/ .+//'

You can get the same results with plain old ifconfig

Using DevFS and have giving up on crond (doesn't work don't know why), i'm using the following for my stats collection:

/usr/local/sbin/post-boot
...
mkdir -p /tmp/wwwstats
while true; do sleep 60; /usr/local/sbin/makeStats; done &
busybox_httpd -p 81 -h /tmp/wwwstats
...

/usr/local/sbin/makeStats
#!/bin/sh

OUT=/tmp/wwwstats/stats.txt

date > $OUT
echo "---" >> $OUT
cat /proc/loadavg >> $OUT
echo "---" >> $OUT
cat /proc/meminfo >> $OUT
echo "---" >> $OUT
cat /proc/net/dev | grep ":" | sed -re 's/ +/ /g' | sed -re 's/ //' | sed -re 's/: /:/' | sed -re 's/ .+//' >> $OUT
echo "---" >> $OUT

Then, its up to Cacti to do the job via a http get on http://192.168.1.1:81/stats.txt
