We built our own system for this purpose and just spawn one process per device being polled. This seems to work out OK and many cores can make this work out. You can also just split the workload horizontally across multiple servers. The challenges are as usual how to report from a dataset like that. Many systems exist to distribute workload across the servers. Custom poller is really the way to go here IMHO. It’s not that hard but requires investment to build it and operate it. - Jared

The idea is to pool about 20 OID's from 50k cable modems in less then 5 minutes (yes, I know it's a one million OID's). Before you say check out some very professional and expensive solutions I would like to know are there any alternatives like open source "snmp framework"? To be more descriptive many of you knows how big is the mess with snmp on cable modem. You always first perform snmp walk in order to discover interfaces and then read the values for those interfaces. As cable modem can bundle more DS channels, one time you can have one and other time you can have N+1 DS channels = interfaces. All in all I don't believe that there is something perfect out there when it comes to tracking huge number of cable modems so I would like to know is there any "snmp framework" that can be exteded and how did you (or would you) solve this problem. Thank you.
