Aria operations for Networks (AON) UI shows no flows on the NSX Data source

Products

• VCF Operations for Networks

Issue/Introduction

• From AON UI -> Settings -> Data source, you are not seeing any flows: 
  

• On the NSX Manager UI -> Plan & Troubleshoot -> IPFIX -> Collectors, you confirmed that the collector is added. 

Environment

Aria Operations for Networks

VCF Operations for Networks

Cause

The NSX Manager was added with a user permission different from the "enterprise_admin, network_engineer, or security_engineer" roles, which is required for IPFIX.

Resolution

• Change the user role permissions on the NSX Manager UI -> System ->User Management -> User Role Assignment to following permissions "enterprise_admin, network_engineer, or security_engineer".
• Edit the NSX-T data source on the AON UI, ensure the collector profile selected is correct, add the User with required permission and 'Save' the configuration.
• Toggle OFF the data collection and wait for some time and toggle ON.
• The flows should start to populate the environment (reference image below):
