Description

The New-AzNetworkWatcherPacketCaptureV2 cmdlet creates a new packet capture resource and starts a packet capture session on a VM, VMSS or few instances of VMSS. 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

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.

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 scale set and all the respective instances adhering to the latest vmss model, to create packet captures.
