"vRNI-Node_Group_Profile_TN_<UUID>" Group is Not Recreated in NSX-T by Aria Operations for Networks

Products

• VCF Operations for Networks

Issue/Introduction

• Temporarily remove the NSX-T data source from AON, then re-add it after a short period.
  
  
• The ns-group:vRNI-Node_Group_Profile_TN_<UUID> that existed before removing the NSX-T data source is not recreated on the NSX-T side after re-adding the data source.
  
  
• Checking the collector log (latest.log) during data source initialization confirms that the latency setting is set to false:

Environment

VMware Aria Operations for Networks
VMware NSX

Cause

• The NSX-T Group vRNI-Node_Group_Profile_TN_<UUID> is specifically associated with the Network Latency Statistics feature.
  
  

• The system will only create and maintain this specific group if the "Enable Latency Metric Collection" option is checked within the Data Source configuration. 
  If this option is disabled, the collector will not attempt to recreate the group if it is missing or deleted.

Resolution

If the collection of latency metrics is not required, the absence of this group is expected behavior and no action is needed.
If the group is required (or if you wish to enable latency statistics), perform the following steps:

1. Log in to the VMware Aria Operations for Networks user interface.
2. Navigate to [Settings] > [Accounts and Data Sources].
3. Locate the specific NSX-T Manager data source.
4. Click the ellipsis icon (...) on the right and select [Edit].
5. Under Additional Information, locate the checkbox for [Enable Latency Metric Collection].
6. Ensure the checkbox is Checked.
7. Click [Submit].

Once the configuration is updated and the next polling cycle completes, Aria Operations for Networks will recreate the necessary groups in NSX-T.
