I/O and Network Usage

Thanks for the ideas. Actually, you can add the network usage adding {net} sensors. You can add it in the preferences menu-item. We are working in a help message with the explenation of others feature than memory and CPU usage.

It requires 'ifstat' on the system. But when I installed it from the repository it is always fixed showing "↓0kB/s ↑0kB/s". Is there any other settings required? I am using Ubuntu 12.10.

I think it doesn't need other dependeces, but I'm not completly sure. Anyway...
Is ifstat working correctly in your system? Run ifstat in a console and see if the output is different from "↓0kB/s ↑0kB/s".

Try running it en a console and see if the output is usefull.

What version are you runing? You can try the latest version, it has some improvements. You install like this:
$ rm ~/.indicator-sysmonitor.json
$ bzr branch lp:indicator-sysmonitor

and then execute it
$ ./indicator-sysmonitor/indicator-sysmonitor

ifstat is working properly. Numbers are non-zero and appearing normal (for
example when listening to streaming radio). The version I am currently
using is 0.5.1~unreleased. I did the procedure you described, still the
same result, network data does not change than zero.

Cheers,
Hamid

This is really strage. I looked at the code and the operation is really simple. It just put in the systray the output of the next command

$ ifstat -a -n -q -S -T 0.5 1 | tail -1 | awk '{ printf("↓%dkB/s ↑%dkB/s ", $6, $7)}'

If it shows "↓0kB/s ↑0kB/s" there is some wrong in the command.

I always use the app with ubunut 12.04. Anyway I'm going to test it in 12.10. Give me some time to install it.

Please run in a console and paste the output here.
Also, paste here the customize output. (Preferences => Advance)

Well it is like what you guessed:
"↓0kB/s ↑0kB/s" $
Outputs once and then the prompt.

Thanks

So, that is the problem. Give me the output of the next commands

$ ifstat -v
$ ifstat -a -n -q -S -T 0.5 1
$ ifstat -a -n -q -S -T 0.5 1 | tail -1

Anyway, this is a bug, when I have some time i'll try to replace the requirement of ifstat

Here:

$ifstat -v
ifstat version 1.1.
Copyright (C) 2001-2003, Ga�l Roualland <email address hidden>
Compiled-in drivers: proc, snmp.

$ifstat -a -n -q -S -T 0.5 1
        lo eth0 wlan0 Total
 KB/s in KB/s out KB/s in KB/s out KB/s in KB/s out KB/s in KB/s out
    0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00

$ifstat -a -n -q -S -T 0.5 1 | tail -1
    0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00

OK, I realized there is a big problem. The output will be different depending on the number of net interfaces. I think a real solution is replace the code without using ifstat. I working on that and let you kwow when I finish.
Thanks for discover the bug.

Hamidreza, I uploaded a fix.
Reinstall everything

$ rm ~/.indicator-sysmonitor.json
$ bzr branch lp:indicator-sysmonitor
$ ./indicator-sysmonitor/indicator-sysmonitor

Thanks Gabriel! It works, but there is one problem: as the figures change it takes more or less space on the panel, and thus shifts everything right or left accordingly. I searched a bit but seems there is no easy way to reorder items in the panel so that one places sysmonitor in the end. Is there a way to pad network numbers with space characters so that a number takes always three places?

you're welcome Hamidreza! The API which puts text in the systray is very limitated, but it is possible to fix the problem you mention. I'm going to try it in march or april because I'm busy right now.
