Network Watcher - Enable

Hi JB,

Thanks for reaching out in Microsoft Q&A forum,

We continue to receive the recommendation to enable Network Watcher, but Network Watcher is showing that it is enabled. What are we missing?

Network Watcher recommendations often persist if the service is enabled at the subscription level but not provisioned in specific Azure regions where your resources reside.

Check the status:

In the Azure Portal, navigate to Network Watcher > Regions. Confirm "Enabled" status for all regions containing your VNets, VMs, or gateways disabled regions trigger alerts.

List via CLI:

az network watcher list --query "[?provisioningState=='Succeeded'].{Region:location}"

Enable in Required Regions:
For each region (e.g., "East US"):

az network watcher configure --resource-group NetworkWatcherRG --locations "East US" --enabled true

This creates the NetworkWatcherRG group and instance if needed.​

Azure Advisor scans all regions containing networking resources (VNets, NICs, NSGs, Load Balancers, etc.) and flags any without a corresponding Network Watcher instance like NetworkWatcher_<region>. Your screenshot shows coverage for East US/East US 2, but overlooked resources elsewhere (common in multi-region setups) trigger the alert. Advisor ignores the Network Watcher blade and focuses on resource locations.

Run it in Azure Resource Graph Explorer (portal search):

• Match results against az network watcher list output.
• Enable NW in any gaps: az network watcher configure --locations "<region>" --enabled true.
