Perhaps - I meant things that were available via snmp where it is
basically a matter of adding the device name/ip and community string.
One thing that is particularly nice about cacti is that there is a data
export link associated with each graph if you want to do more detailed
analysis of the samples with some other program. Opennms has a way to
get avg/min/max of values for a specified time span but it is cumbersome
if you want fine-grained samples.

It would probably be a good time to start since they just released the
1.8 version. It comes up basically working if you just give it IP
ranges to discover so you don't have to learn much to get started. You
do need decent hardware if you expect to collect a lot of graph data though.
