Question:
We have a 56K line coming into our office.
This line goes into a Livingston IRX 1-11 PortMaster
router. Our Lan is a bus.
I am using a Sparc 10 with Solaris 2.5.1 with one ethernet
interface le0.
I am trying to figure out how much of the 56K we
actually use, i.e. I want to montior it / log it ...
(I already have software for analyzing the ethernet.)
I want something to tell me what percentage of
the 56K is being used by us, because it could actually
be cheaper to pay per volume of traffic on a fractional
T1 line than it is to pay for our current 56K line.
Answer:
This is what I am now using.
1. I enabled SNMP in the Livingston PortMaster.
2. I installed ucd-snmp-3.1.2
from UCDavis at: ftp://ftp.ece.ucdavis.edu/pub/snmp/
This is a strain of the original CMU code.
Its easy to compile and configure.
3. I installed a package called router-stats from:
http://www.scn.de/~iain/router-stats/
This is a collection of Perl scripts that are easy to configure
and generate HTML pages containing gifs of your routers usage
statistics.
And a few simple crontab entries takes care of the statistics
collection and generation when all is working.
Some other suggestions:
- bing from http://web.cnam.fr/Network/bing.html
It is a Bandwidth pING.
This I use all the time. It is very useful.
- Driver Aces, Inc. IP Quota software - IPCTL
This is quite useful especially if you are a
site that is charged based on network usage.
I'll take a closer look when I get time.
- MRTG, a SNMP package from http://mailer.gu.se/traffic/mrtg.html
This uses cmu-snmp.
mrtg and cmu-snmp can be found at:
ftp://ftp.dmu.ac.uk/pub/netcomm/src/internet/
I wasted a lot of time trying to compile and configure these.
- Ask our ISP for router statistics.
I did this and I got some poor quality faxes of a printout
of some postscript to gifs. When asked what software they used
I received a reply that it was home-grown and hey they were
going to start offering router usage statistics for a fee.
- For a router that supports SNMP check out Neon Software
http://www.neon.com/. They sell a product called CyberGuage
for the Mac.
- I would like to recommend scotty-2.1.5. It contains a network
editor called Tkined (tkined1.4.5) that requires Tcl 7.5 and Tk 4.1.

They are available from:
ftp://ftp.ibr.cs.tu-bs.de/pub/local/tkined/,
ftp://netlab-c.mscs.mu.edu/scotty/
