VNA Multitenancy integration

Products

• CA Virtual Network Assurance

Issue/Introduction

We are planning a multi-tenancy integration between VNA and Spectrum / PM, I read on Spectrum docs the VNA Aggregator integration, but nothing else. So, I need your help to locate these: 
- How to configure the VNA Aggregator.
- How to integrate PM with a VNA Aggregator. 

Environment

Release : 3.7

Component : Virtual Network Assurance For CA Performance Management

Resolution

The VNA aggregator is only used with Spectrum.

The CA PM (Performance Center) does not use the aggregator at all.
