grep current rx and tx speed

replica9000 · 02-06-2008, 10:47 PM

Is there a command I can use with grep to get the current rx and tx speeds in terminal without root privileges?

rx and tx speeds of what?

If you mean a wireless interface, iwconfig should show that to you, even as non-root.

Run something like this:

Code:

/sbin/ifconfig eth0 | grep 'TX bytes'

Result on RHEL:

Code:

$ /sbin/ifconfig eth0 | grep 'TX bytes'
          RX bytes:6379743404 (5.9 GiB)  TX bytes:16551093106 (15.4 GiB)

==============================
Edit:
sorry, my bad...

That's not what I'm looking for, that's the total rx / tx bytes downloaded, unless my laptop is downloading at 68.8 GiB/s. I'm looking for the download rate. Like when I'm downloading a file, I wanna be able to grep the rate the file is downloading at.

slurm -i eth0 shows me this, but I can't grep the output.

The reason I want to do this is I use SuperKaramba to monitor my network speed. But it greatly exaggerates the actual speed (by about 10x), even on multiple machines.

I was looking to replace this line in my .theme file:

Code:

sensor=network format="%inkb Kbps" device="eth1"

With something similar to this:

Code:

sensor=program program="slurm -i eth1 | grep 'Current TX Speed' cut -d ' ' -f20,21" interval=1000

Except like I said grep doesn't work with slurm, and ifconfig only gives the total downloaded or uploaded.

then try ethstats it's a perl script that reads /proc/net/dev and print out in/out speed i MB/s. Maybe by analyzing this script you can develop you own...

Are you looking for speed in KBps instead of Kbps? That might be the issue.

ok, i've foun what you have been looking for ^_^ it's vnstat but it has a 5 sec delay T_T... and i wrote simple line to get rates ^_^:

Code:

dawid@rei:~$ vnstat -i eth0 -tr
1008 packets sampled in 5 seconds
Traffic average for eth0

      rx          37.57 kB/s             87 packets/s
      tx         136.29 kB/s            114 packets/s

dawid@rei:~$ vnstat -i eth0 -tr | grep rx
      rx          44.85 kB/s             93 packets/s
dawid@rei:~$ vnstat -i eth0 -tr | grep tx
      tx         124.51 kB/s            115 packets/s
dawid@rei:~$ vnstat -i eth0 -tr | grep rx | awk '{print "RX rate: " $2 " " $3}'
RX rate: 62.18 kB/s
dawid@rei:~$ vnstat -i eth0 -tr | grep tx | awk '{print "TX rate: " $2 " " $3}'
TX rate: 120.54 kB/s
dawid@rei:~$ vnstat -i eth0 -tr | grep rx | awk '{print "RX rate: " $2 " " $3 " (packets: " $4 ")"}'
RX rate: 40.00 kB/s (packets: 81)
dawid@rei:~$ vnstat -i eth0 -tr | grep tx | awk '{print "TX rate: " $2 " " $3 " (packets: " $4 ")"}'
TX rate: 125.81 kB/s (packets: 125)
dawid@rei:~$

maybe this can help you...

Yes that was the issue!
I looked into the SuperKaramba options and found out that %outkb=kilobits/sec and %out=kilobytes/sec

Thanks!

Thanks for this info also, might help me with other things down the road.
