Sflow settings recommendations wanted

I have an Alcatel network with about 70 switches so need to use sflow as opposed to netflow.
What are Scrutinizer’s best practice settings for sflow on my switches.
I have seen everything from a sampling rate of 1 to 2048 and polling intervals from 5 seconds to 30 seconds used but no actual recommendations for a Scrutinizer setup. Obviously I want accurate data but I don’t want unnecessary traffic on the network if it’s not going to make much difference.

Hello Gardned1,

If you would like to email me at adam.howarth[at] with specific model information I can provide you with a recommendation.

Typically the parameters of sflow are configured in a way that captures the most sampling data, without incurring too much overhead on the switch.

Thank you,
