I'm able to poll a few thousand CMs in a few seconds using perl's Net::SNMP and
async calls. 50k seems pretty doable.

Hi all,
recently I have been tasked with a NMS project. The idea is to pool
OpenNMS has a poller that will do what you want. The problem is
figuring out what you wish to collect and how to use it. Most of the
time it's not as simple as pointing at the modem and saying go.
I've added a few oids for some of the modems we support, just so I can
get SNR on them. I

Hi all,
recently I have been tasked with a NMS project. 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
Pavel,
AFAIK there are no frameworks that solve, or even come close to solving,
this problem. The first thing to learn is how to do asynchronous SNMP
calls that will let you send out requests without having to wait for the
response. How you do those will vary by the language that you're using.
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
