And I've done something similar ... what would be nice is a /proc
interface for reading these values directly without an exec.

Now there are 3 of us we did it :)
But the /proc interface isn't a bad idea.  Anyone has an idea how to do this?

I can have a look at it, probably the netfilter code would need to be
changed.

Would be a good idea to have packet count, and other things in /proc?
What do the people with experience in the kernel think?

If you do this, please let me know. I would be interested in
adding support for reading these counters via SNMP
to the net-snmp package. It would be good to do the SNMP
work in conjunction with the kernel code so we make sure
that the two both do the things they expect of each other.

Whatever it is, make sure its easily parsed (tab-delimited, etc.)

There should probably be seperate class and queue lists for simplicity.

For queuing disciplines:
	Type of qdisc, handle, packets, dropped packets, borrowed packets
	Also optionally: time since last dequeue, time since last queue, etc.

Any other thoughts?

if possible, count bytes as well as packets

[LARTC] Graphing

[Sahil Gupta - Net4U Limited]

Hi there,
We currently use CBQ to traffic-shape our boxes.  Just wondering, does
anybody know of a way to graph the traffic flowing to netblocks / ip
addresses?

Cheers,
Sahil

I create graphs based on the tc-counters.  
http://home.docum.org/stef.coene/qos/gui/rrd.html
I also monitored what-ever-I-wanted with the counters of iptables/ipchains.  
But I have no graphing script for this.

Stef,
Are you using SNMP?  We currently have a great model working using
SNMP/MRTG but, we want to get away from SNMP as it isn't as accurate as we
would like it to be.  We are really looking for information off the router
itself.... are you able to shed any light to it?

Cheers,
Sahil

I use SNMP so I can monitor the box remotely.  But what do you mean with "it 
isn't as accurate as we would like it to be.  We are really looking for 
information off the router itzelf" ??

MRTG is great to monitor devices, but for custom made monitor, you better 
create your own scripts.

I'm leaving for holiday tomorrow morning, so it's possible that you will have 
to wait 2 weeks for an answer on you mails.

[LARTC] graphing

[jacob martinson]

Does anyone know what Martin used to generate the graphs in the HTB user guide?

http://luxik.cdi.cz/~devik/qos/htb/manual/userg.htm

Thanks!

Do you mean the class tree graphs? You can use GraphViz to generate those,
maybe with the help of a script like 
http://www.metamorpher.de/files/tc-graph.pl which creates graphs (together 
with GraphViz 'dot') like these 
http://www.metamorpher.de/files/fairnat.png (big!).

If you mean the statistic graphs, maybe these were done with RRDTool or 
similar. There are scripts that create this kind of graph as well, but I 
haven't got an example URL handy. Maybe someone else on this list can 
provide one.

Yep, it's a perl script to process the counters and I gnuplot to create the 
graph.  I used the same scripts to create my graphs, so I downloaded it 
somewhere from his site.
If you can't find the scripts, let me know and I will try to find mine.

I think Martin used the following tool to transmit frames:
http://luxik.cdi.cz/~devik/qos/ethloop/
and I suppose he used gnuplot to graph, I also did some graphs 
on HTB visible at http://rawsoft.org with ethloop and gnuplot.
