Thank you all for you suggestions, I knew it that NANOG is a perfect place
for those kind of questions.
I will discuss your comments with my colleagues to see what would be the
best solution.
Once again thank you all for your valuable suggestions, I hope I will
update you soon with some results/test and of course more questions :)

We have used ZenOss for a number of years at this scale (40k+ devices, at
intervals of 1-5 minutes). It is possible to do if you have the hardware
and storage performance to throw at it. We used OpenNMS before that and had
to change due to scale. During that time we evaluated a number of the big
name and big dollar solutions and none of them seemed to scale any better
without significantly more hardware costs.
That's not to say ZenOss is perfect, we have plenty of headaches too.

So we have used www.zenoss.org<http://www.zenoss.org> for many years. Individual collectors
are easily handling snmp poll rates of 1.5k oids per second(450k per 5m).
As zenoss core is open source Its probably worth a look for you.

Subject: SNMP - monitoring large number of devices

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 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.
