I'm about to begin writing a program using the curses library and I'm not 100% sure how to structure it (which is why I have no active code).

The program is going to histogram info retrieved via snmp from a cable plant.

What needs to happen is this:

1. The CMTS is queried via snmp for a list of registered modem ips.

2. Generate/update a hash with the ips.

3. Query each IP for 2 values and store them in the hash. Repeat on an interval.

4. Calculate statistics on the recorded values

5. Print a histogram and associated stats to the screen, dynamically updating on a fixed time basis.

So I'm thinking of having one forked process running on a schedule (on invoked by a key) to poll the cmts to update the list of IP's.

I'd then have another forked process to march through the hash, running the snmp queries and updating the values. Would having an individual process for each IP (200+ in some circumstances) be too much?

Lastly, I'd have a process that does nothing but process the data in the hash and generate the UI.

Does this sound like a reasonable approach?
