Re: NetFlow - path from Routers to Collector
Agreed, we are as well :) VLAN, VRF, whatever. + optimal tweaks include local flow proxy that can also rate limit / re-sample, and send topk talkers over 'true' OOB. Avi Freedman CEO, Kentik avi at kentik dot com

~20% matches our subjective observations, as well.
We're doing our best to increase that number.

Yes, a lot of distributed flow collection/analysis architectures are deployed this way, doing more than top-talkers, even. The key is that traffic between the elements of those types of deployments *must* not be disrupted; true OOB is preferred, but VLAN/VRF is still the norm, there. ----------------------------------- Roland Dobbins <rdobbins@arbor.net>
