[plug] Traffic Monitoring

[Ben Jensz]

MRTG isn't that hard to setup, if you're just going to be monitoring network
bandwidth then its quite simple to setup, the hardest part of it is setting
up ucd-snmp (net-snmp - http://net-snmp.sourceforge.net/).  MRTG comes with
a script called "cfgmaker" which when pointed to the machine running the
snmp daemon with the right access community will just find all valid network
interfaces and write the config for it.

If you want to go beyond doing just network traffic graphing, you can graph
almost anything that snmp will give a value for.  I've got it setup to
monitor network, CPU, memory and disk usage on my work's servers (and the
Linux games servers I run in Perth as well).

It depends how complex you want to go :).  But for just doing network usage
graphing, its pretty easy, it appears harder at first than it really is :).

Hi,
I need to monitor all traffic going through all of our clients Linux
gateways.  What's the best way to do this, with minimal configuration?
I looked at MRTG but that has a lot of configuration, I will use it if there
is no others but I thought I would just check first.
Thanks
