Description

The New-AzNetworkWatcherPacketCapture cmdlet creates a new packet capture resource and starts a packet capture session on a VM. The length of the Packet Capture sessions can be configured via a time constraint or a size constraint. The amount of data captured for each packet can also be configured. Filters can be applied to a given packet capture session, allowing you to customize the type of packets captured. Filters can restrict packets on local and remote IP addresses & address ranges, local and remote ports & port ranges, and the session level protocol to be captured. Filters are composable, and multiple filters can be applied to provide you with granularity of capture.

Examples

Example 1: Create a Packet Capture with multiple filters

$nw = Get-AzResource | Where-Object {$_.ResourceType -eq "Microsoft.Network/networkWatchers" -and $_.Location -eq "WestCentralUS" } 
$networkWatcher = Get-AzNetworkWatcher -Name $nw.Name -ResourceGroupName $nw.ResourceGroupName 

$storageAccount = Get-AzStorageAccount -ResourceGroupName contosoResourceGroup -Name contosostorage123

$filter1 = New-AzPacketCaptureFilterConfig -Protocol TCP -RemoteIPAddress "1.1.1.1-255.255.255" -LocalIPAddress "10.0.0.3" -LocalPort "1-65535" -RemotePort "20;80;443"
$filter2 = New-AzPacketCaptureFilterConfig -Protocol UDP 
New-AzNetworkWatcherPacketCapture -NetworkWatcher $networkWatcher -TargetVirtualMachineId $vm.Id -PacketCaptureName "PacketCaptureTest" -StorageAccountId $storageAccount.id -TimeLimitInSeconds 60 -Filter $filter1, $filter2

In this example we create a packet capture named "PacketCaptureTest" with multiple filters and a time limit. Once the session is complete, it will be saved to the specified storage account. Note: The Azure Network Watcher extension must be installed on the target virtual machine to create packet captures.
