HELP: Need info on monitoring network bandwidth

Hi gang,

I am trying to find a utility which will allow me to monitor the total
transmit and receive bytes for my network device over the period of a
month - essentially something like webalizer for my network.

Can anybody point me in the right direction?

I tried MRTG and can't seem to get it to work.

I get the following error when I try to use the cfgmaker script:

[ERROR]

I'll hope that someone with Mandrake snmp experience will assist you, but
suspect that you'll need the ucd-snmp, ucd-snmp-utils and perhaps the :
ucd-snmp-devel rpm. "man -k snmp" should reveal what tools net-snmp has
placed on the system, but you should have something likeis presented at
http://www.hlug.org/presentations/sn...snmp-utils.php

Also, is there any firewall issue with snmpd listening on port 161 tcp/udp
and/or udp 162? Have you verified the snmpd.conf file after a "man
snmpd.conf"?

The error you reported previously was:
--base: Get Device Info on (E-Mail Removed):
SNMP Error:
no response received
SNMPv1_Session (remote host: "aurora.borealis.org" [192.168.0.100].161)

There was no response received, so some of the above suggestions may be
useful to you. You might also examine line 570 in
/usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi/SNMP_util.pm and
line 709 in /usr/bin/cfgmaker to see what's expected. "cat -n file | less"
and then search for the line number is the easiest way to quickly check.

Thanks for your help! When I read your last post .. I wondered if snmpd was
running - it was not !! DOH !!
Everything is working like a charm now.

Regarding the above packages .. the ucd-snmp-* version is OLD and no longer
supported .. the replacement is net-snmp-*

Hope this info helps anyone who has similar problems.

Thanks again Tony.

James,
Depending upon what you decide to implement you might find
OSM useful. Part of the design of OSM is that, once the sysadm has
a working solution (using amy s/w technologies that write to
stdout and place errors on stderr) they can be a simple plugin
to OSM. You get a true web interface without any of the work.

http://ftp.opensysmon.com is a shell script archive site with an
open source system monitoring and network monitoring software package.
Many platforms are supplied already compiled.

That's good to know, and thanks for posting that info to Usenet so that
others may benefit from it when they search the archives.

One of the good things about mrtg is the ability to schedule a cron job that
queries all the network interfaces of interest on the LAN including the
external. It really gives a good idea of where any bottlenecks might be
occurring.

I noticed recently that gkrellm2 has this built in, hover your mouse of the
ethernet card window, a button will appear with the said stats wanted inside.

It will only work whilst gkrellm2 is running of course though. Its a simple,
zero configuration tool.
