Hi Antonios.

As a necessety for my job is to real-time monitor the bytes, packets, packet dropped etc of all the qdiscs working inside the kernel i've tried varius methods:I have developed myself a similar setup, but i used a perl script with snmp pass_persist to retrieve the data via snmp feed it to MRTG and then display it with a CGI script, since i changed jobs recently i made some changes to the setup and was thinking in creating a sourceforge project.
1. Parse tc -s command output and update a round robin database and use rrdtool to graphically display tc statistics.
But i don't think it is ready for that yet, i mean, it is working beautifully for me (and in my previous employer) but there are some rough edges to address first.
Btw, the setup generates TC, iptables and MRTG configuration from a config file.
I think it is time to see how can the setup be improved.
[varius perl scripts exist for the above job]
2. Unsuccesfully tried QoS SNMP extensions, in order to use a new MIB to extract qdisc stats from.
There is also some work in the kernel level that will help reveal qdisc stats to userspace (thanks Thomas Graf)
I have never heard of this, must google it.
To get to the point.. the perl parsing method is hackish and quick&dirty.I really never tried to write a better tool, with less 'tc -s' parsing, don't have the time or incentive to hack the needed code, so can't help you there :-)
A proper open-source tc monitoring tool SHOULD exist ! Maybe inside iproute2 maybe in sourceforge.
Are there any volunteers to start working on such a project? I could put 4-6 weeks full time work on that... any suggestion for the most proper solution to the above problem is welcome.
I can forward you the software that i use with some documentation.
Thanks,
Antonio _______________________________________________
