You can view the list of all flows that are going over the VTGW, which enables you to view the traffic and helps you to analyze and understand the utilization level of VTGW.
To see all the flows via VTGW, you can run the following query:
flows where tgw = ''
You can see the flows from SDDC to SDDC, SDDC to VPC, and VPC to SDDC via VTGW using the following flow types:
- SDDC-SDDC via TGW
- SDDC-VPC via TGW
- VPC-SDDC via TGW
Note: Flows are not supported between VMC SDDC and on-premise datacenters via
VTGW and Direct Connect Gateway.
