Retirement: Network security group flow logs in Azure Network Watcher will be retired

On September 30th 2027, network security group (NSG) flow logs in Azure Network Watcher will be retired.

As part of this retirement, you'll no longer be able to create new NSG flow logs starting June 30th, 2025. We recommend migrating to virtual network flow logs in Network Watcher, which overcomes the limitations of NSG flow logs and provides enhanced capabilities.

Required action

To avoid service disruptions, migrate to virtual network flow logs by September 30th, 2027.
