You can use this topic to learn how to operate the tool and understand its output. The extension helps you diagnose your network by capturing and displaying network traffic through the networking stack in a log that is easy to follow and manipulate. The Packet Monitoring extension allows you to operate and consume Packet Monitor through Windows Admin Center. Packet Monitoring Extension in Windows Admin Center You can use this topic to learn how to understand pktmon syntax, commands, formatting, and output. Packet Monitor is available in-box via pktmon.exe command on Vibranium OS (build 19041). The following resources are available to help you get started using Packet Monitor.

Ethernet, Wi-Fi, and mobile broadband media type support.

Multiple logging modes: real-time, high volume in-memory, multi-file, circular.

TXT log analysis based on TcpDump packet parsing.

General logging and tracing support (ETW and WPP events).

Flexible runtime packet filtering with encapsulation support.

Packets drop detection at multiple stack locations.

Packet monitoring and counting at multiple locations along the networking stack.

Packet Monitor offers the following functionality:

Look into the log for detailed analysis (pktmon format pktmon.etl).

Check packet counters during the experiment for high level view (pktmon counters).Configure packet filters matching your scenario (pktmon filter add).Check command-line help for arguments and capabilities (e.g.Use these best practices for streamlining your network analysis. Packet Monitor also provides packet counters for each intercept point, enabling a high-level packet flow examination without the need for time-consuming log analysis. These drop reasons provide the root cause of the issue without the need to exhaust all the possibilities. Additionally, Packet Monitor will report drop reasons for example, MTU Mismatch, or Filtered VLAN, etc. This allows users to differentiate between a component that is the intended destination for a packet and a component that is interfering with a packet. If a packet was dropped by a supported component in the networking stack, Packet Monitor will report that packet drop. Packet Monitor intercepts packets at multiple locations throughout the networking stack, exposing the packet route. Packet Monitor provides the enhanced visibility within the networking stack that is often needed to pinpoint these mistakes. Such a flexible environment allows for much better resource utilization and security isolation, but it also leaves more room for configuration mistakes that can be hard to diagnose. This extended networking stack now includes components like the Virtual Switch that handle packet processing and switching. However, with the advent of network virtualization, the size of the networking stack has multiplied. In traditional scenarios, the networking stack is small, and all the packet routing and switching happens in external devices. All the components between this adapter and an application form a networking stack: a set of networking components that process and move networking traffic. OverviewĪny machine that communicates over the network has at least one network adapter. It is available in-box via the pktmon.exe command and via Windows Admin Center extensions. The tool is especially helpful in virtualization scenarios, like container networking and SDN, because it provides visibility within the networking stack. It can be used for packet capture, packet drop detection, packet filtering and counting. Packet Monitor (Pktmon) is an in-box, cross-component network diagnostics tool for Windows. Applies to: Windows Server 2022, Windows Server 2019, Windows 10, Azure Stack Hub, Azure, Azure Stack HCI, versions 21H2 and 20H2
