Aria Operations for Networks features work intermittently with NSX-T Data Center version 3.x

Products

• VCF Operations for Networks
• VMware NSX

Issue/Introduction

• In Aria Operations for Networks version 6.13, optimizations have been made around the NSX-T logical ports, such that the logical port SDMs are distributed to all containers based on logical switch ID.
• You see entries similar to the following in the collector logs at /home/ubuntu/logs/collector/.
  

  ubuntu@aria-networks-collector:~$ grep "Actual inventory size" /home/ubuntu/logs/collector/ -r | grep "LogicalPort"
  2024-06-28T09:54:48.170Z INFO nsxt.tasks.InventoryHandler NSXT_##.###.##.###_Config_OpMgr-1 invoke:59 Actual inventory size 20, fetched entities size for 23, LogicalPort

• VM to VM path works intermittently. If you are searching the VM to VM path when the logical port is deleted then you won't see the path.
  
  
  
  
• Network Assurance and Verification Path : VMs with networking provided by NSX-T (logical switch/segment) will be visible intermittently in the network map.
  
  
  
  
• Most of the flows will be dropped at the collector due to Non domain of NSX-T.
  
  You can check this from flow-processor logs using a command as similar to the following:
  
  grep "NON_DOMAIN_NSXT_FLOWS:" /home/ubuntu/logs/flow-processor/ -r | grep -v NON_DOMAIN_NSXT_FLOWS:0 | tail
  
  Note: You will see output similar to the following:
  
  

Environment

Aria Operations for Networks 6.13.0
VMware NSX-T Data Center (3.x)

 

Cause

Logical port Inventory is not sent to the Platform. There is mismatch between the totalInventory and the inventory size. Here, totalInventory is the cumulative ports count and inventory is the set of logical port Ids.
Internal ports are not included into the totalInventory, but are added to the inventory set. Due to this, the inventory is not sent to the platform. 

The consistency checker will delete the logical ports in Aria Operations for Networks if that logical port id is not present in inventory.

Resolution

This issue is resolved in VMware Aria Operations for Networks 6.14.0 and VMware NSX 4.x
