Use MRTG or HP-Openview to look at how much data goes through what
interface at what time. Use Netflow to get a good idea of where the
bul of it is going to and from (never captures 100% of the information
it seems). Use ip accounting and/or ip access list with log to track
down individual usage elements (security etc.).
MRTG is certainly easy to use and draws pretty graphs. I have not deployed
it on a very large collection scale. HP/OV has good SNMP spacing and
collection stuff. It would be possible to use MRTG from OV data though
we don't do this.
But Paul is right - Netflow is very useful.
