![]() Add a new network event session with New-NetEventSession.There are six basic steps required to perform a network trace: Six basic steps to perform a network trace So I don’t need anything else to be able to read my traces. And guess what? Windows PowerShell already has a cmdlet that will read ETL logs-the Get-WinEvent cmdlet. ![]() I can, of course, tell if my laptop is seeing anything on the wire-but that is basically the same as looking to see if the light blinks on my network card.Īs I have mentioned before, ETL logging is an extremely high performance logging interface that is capable of writing hundreds of events a second- just the thing if I want to do a network trace. Many of them are encrypted, and I can learn nearly nothing by watching network packets fly past. With a gigabyte Ethernet (or greater), there are lots of packets flying by on the wire. ![]() I mean, how do I do a basic network trace? How is that trace viewed? How do I filter that trace to find useful information? These are the sorts of things that I would need if I were going to do a network trace using Windows PowerShell. TechNet does a good job at describing the cmdlets, but there is also a pretty good chance that it will be rather cumbersome to figure out how to get started. PS C:\> gcm -Module NetEventPacketCapture | select name PS C:\> (gcm -Module NetEventPacketCapture | measure).count This is because there are 27 cmdlets in the NetEventPacketCapture module: The thing is that even though it is basic Windows PowerShell, it still takes a bit of time to figure out how to get started. Although the Network Event Packet Capture cmdlets have been around for at least a year, I have not written very much about them. ![]() In the past, I have used batch files, automated the NetMon API, and done all kinds of crazy things to try to automate capturing network traces and analyzing the data. I have found network tracing extremely useful and helpful in troubleshooting and diagnostics ever since I wrote my book, Network Monitoring and Analysis: A Protocol Approach to Troubleshooting. One of the way cool things that happened with Windows 8.1 and Windows Server 2012 R2 was the ability to do network traces with Windows PowerShell. Microsoft Scripting Guy, Ed Wilson, is here. Summary : Ed Wilson, Microsoft Scripting Guy, talks about getting started with packet sniffing in Windows PowerShell. ![]()
