Network Assessment & Value of What-If Analysis section shows "Assessment is not applicable" in VCF Operations 9.1.x

Products

• VCF Operations

Issue/Introduction

When navigating to Manage > Capacity > Plan > What-If Analysis > Network Assessment & Value and selecting a specific vCenter Server from dropdown in VCF Operations, you observe the following message despite having NetFlow enabled in the vCenter adapter enabled:

Assessment is not applicable. Currently, there is no hair pinned traffic for the selected vCenter

Environment

VCF Operations 9.1.x

Cause

This is expected behavior when there is no hair pinned traffic. The message is displayed because there is no hair pinned traffic currently occurring on the selected vCenter Server.

Resolution

To verify that there is no hair pinned traffic for the affected vCenter Server, kindly perform the following steps:
1. Log in to the VCF Operations for Networks platform.
2. Enter the following query into the search bar (replace <vcenter_fqdn> with your actual vCenter Fully Qualified Domain Name):

flows where typeTag = 'Routed' and typeTag = 'Same Host' and manager = '<vcenter_fqdn>'

3. Review the results. If no flows are returned, it confirms that no hair pinned traffic exists, validating that the user interface message is correct.

Note: If you see the flows, please open a Broadcom Support Case and refer this KB 442416.
