Description

The Set-AzNetworkWatcherConfigFlowLog configures flow logging for a target resource. Properties to configure include: whether or not flow logging is enabled for the resource provided, the configured storage account to send logs, the flow logging format, and the retention policy for the logs. Currently Network Security Groups are supported for flow logging.

Examples

Example 1: Configure Flow Logging for a Specified NSG

PS C:\> $NW = Get-AzNetworkWatcher -ResourceGroupName NetworkWatcherRg -Name NetworkWatcher_westcentralus
PS C:\> $nsg = Get-AzNetworkSecurityGroup -ResourceGroupName NSGRG -Name appNSG
PS C:\> $storageId = "/subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Storage/storageAccounts/contosostorageacct123"


PS C:\> Set-AzNetworkWatcherConfigFlowLog -NetworkWatcher $NW -TargetResourceId $nsg.Id -EnableFlowLog $true -StorageAccountId $storageID

TargetResourceId : /subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Network/networkSecurityGroups/appNSG
StorageId        : /subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Storage/storageAccounts/contosostorageacct123
Enabled          : True
RetentionPolicy  : {
                     "Days": 0,
                     "Enabled": false
                   }
Format           : {
                     "Type ": "Json",
                     "Version": 1
                   }

In this example we configure flow logging status for a Network Security Group. In the response, we see the specified NSG has flow logging enabled, default format, and no retention policy set.

Example 2: Configure Flow Logging for a Specified NSG and set the version of flow logging to 2.

PS C:\> $NW = Get-AzNetworkWatcher -ResourceGroupName NetworkWatcherRg -Name NetworkWatcher_westcentralus
PS C:\> $nsg = Get-AzNetworkSecurityGroup -ResourceGroupName NSGRG -Name appNSG
PS C:\> $storageId = "/subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Storage/storageAccounts/contosostorageacct123"


PS C:\> Set-AzNetworkWatcherConfigFlowLog -NetworkWatcher $NW -TargetResourceId $nsg.Id -EnableFlowLog $true -StorageAccountId $storageID -FormatVersion 2

TargetResourceId : /subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Network/networkSecurityGroups/appNSG
StorageId        : /subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Storage/storageAccounts/contosostorageacct123
Enabled          : True
RetentionPolicy  : {
                     "Days": 0,
                     "Enabled": false
                   }
Format           : {
                     "Type ": "Json",
                     "Version": 2
                   }

In this example, we configure flow logging on a Network Security Group (NSG) with version 2 logs specified. In the response, we see the specified NSG has flow logging enabled, the format is set, and there is no retention policy configured. If the region does not support version you specificed, Network Watcher will write the default supported version in the region.

Example 3: Configure Flow Logging and Traffic Analytics for a Specified NSG

PS C:\> $NW = Get-AzNetworkWatcher -ResourceGroupName NetworkWatcherRg -Name NetworkWatcher_westcentralus
PS C:\> $nsg = Get-AzNetworkSecurityGroup -ResourceGroupName NSGRG -Name appNSG
PS C:\> $storageId = "/subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Storage/storageAccounts/contosostorageacct123"
PS C:\> $workspace = Get-AzOperationalInsightsWorkspace -Name WorkspaceName -ResourceGroupName WorkspaceRg


PS C:\> Set-AzNetworkWatcherConfigFlowLog -NetworkWatcher $NW -TargetResourceId $nsg.Id -EnableFlowLog $true -StorageAccountId $storageID -EnableTrafficAnalytics -Workspace $workspace -TrafficAnalyticsInterval 60

TargetResourceId : /subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Network/networkSecurityGroups/appNSG
StorageId        : /subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourceGroups/NSGRG/providers/Microsoft.Storage/storageAccounts/contosostorageacct123
Enabled          : True
RetentionPolicy  : {
                     "Days": 0,
                     "Enabled": false
                   }
Format           : {
                     "Type ": "Json",
                     "Version": 1
                   }
FlowAnalyticsConfiguration : {
            "networkWatcherFlowAnalyticsConfiguration": {
              "enabled": true,
              "workspaceId": "bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb",
              "workspaceRegion": "WorkspaceLocation",
              "workspaceResourceId": "/subscriptions/bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb/resourcegroups/WorkspaceRg/providers/microsoft.operationalinsights/workspaces/WorkspaceName",
			  "TrafficAnalyticsInterval": 60
            }
          }

In this example we configure flow logging status and Traffic Analytics for a Network Security Group. In the response, we see the specified NSG has flow logging and Traffic Analytics enabled, default format, and no retention policy set.
