We have divided All nodes that we have on Solarwinds into 3 separate groups. What we would like to do is to limit audience receiving alerts from Solarwinds, for example group 1 should receive alerts for only nodes which are added under them , group 2 should receive alerts for only nodes added under them and similarly group 3 should receive alerts only nodes added under them. Basically different types of alerts which are configured on a node should only trigger an email to its concerned group and not all of them.
That's the what do you call it - limitations I think. I would need to check on our environment. But you can do it with limitations. Which are implemented in orion settings and then applied through the limitations of the alerting.
