Hey DavidWanderer, the base Endpoint analytics product is included in Intune, regardless of how you have Intune licensed. The one exception is Remediations (which was previously found under the Endpoint analytics node in Intune) -- to use Remediations, you need Win E3 or higher licenses for the devices/users you want to target. For Intune Advanced Analytics, you will be able to purchase standalone add-on license or licenses for Intune Suite with any subscription that includes Intune. Below are some additional references. Hope that helps!
