Enhancements to NSG flow logs for Azure Network Watcher

Published date: November 16, 2018

We're excited to announce enhancements to network security group (NSG) flow logs for Azure Network Watcher. These enhancements are available in version 2 of the logs. They include per-flow throughput statistics, so you can understand flow session state and the associated number of bytes and packets transferred.

The version 2 configuration of NSG flow logs is currently available only via the Azure portal and REST API in the West Central US region. We are in the process of rolling out these changes to all Azure regions. There will be no impact to existing NSG flow logs or Traffic Analytics customers.

For more information about NSG flow logs, see the product documentation.
