Multiple Servers / SNMP from Switches

[statewide]

Any help regarding this would be greatly appreciated. I think this should be easy if I owned the switches, but the colocation facility owns the switches.
How can I make cacti graph bandwidth info for multiple servers? Here's what I want to do and explain what cacti can do.

I need it to create bandwidth usage graphs where it would grab the info from SNMP from the switches managed by the colocation facility. The software would need to ONLY be installed on server #1. Each dedicated server client would have their own login to server#1 to see their own dedicated server's bandwidth usage graphs. I don't want any software installed on client servers like SNMPd. I only want it installed on Server#1. I want the software to read from the SNMP from the colocation facility's owned switches.

Thank you.

Where can I find the Aggregate plugin?

How does it work? Does it grab the bandwidth usage from the switches? Can I still get the bandwidth usage (for each individual server) from the switches when they are switches owned by the colocation facility?

gandalf, thank you for letting me know about the discussion list post, since I hadn't received the email. I had to visit the discussion list online archive to see the message.

If you have SNMP read access to the switches, this is doable.

But it is a task to relate all switch ports to the related servers and to
provide access to those graphs only, that relate to servers of each respective
client.
All this can be done with cacti

ok, I see. Basically this would be easier if I owned the switches, but since I don't it would be tougher. Even if I owned the switches, I would have to figure out which switch port corresponds with which server. And each would make separate graphs.

For client servers, if they purchased from us a managed server, we would have no problem just installing cacti or MRTG on each server since we'd have access to it and would be the administrator of the server (they have root access if they want it though) to get the bandwidth usage on each server. Then give the client a login to view their bandwidth graphs for their server.

But with unmanaged dedicated servers, I was hoping to find a method of not installing any software on the client server since they would A). not like that, B). would mess with it, C). they could possibly modify it so the bandwidth graph is not accurate since this would be based on their monthly billing. For dedicated servers we bill per GB rather then per MB, but either way the graph is needed for accurate monthly billing. Do you guys have any alternative ideas?

While you still may want to monitor the switches, you only must make sure to know which port is associated with which server.
