Network security group (NSG) flow logs in Azure Network Watcher offer valuable information that help our customers audit their networks in the cloud. Enhancements to the flow logs (version 2) now include byte and packet counts and session state on a per-flow basis. The new metrics provide additional information that can help you better understand capacity utilization and maintain compliance on the network.
These enhancements to NSG flow logs are now available in all public cloud regions.
Traffic analytics, our cloud-based network analytics solution, has been upgraded to use the additional flow data that's available in NSG flow logs version 2. Version 1 continues to be available.
