SCVMM Tracing Made Easy! - Jonathan's Virtual Blog - Site Home

This tool has been deprecated. Please see the new tool!

So you’ve run into a problem with VMM. Maybe your Hosts have lost connectivity with the SCVMM Server. Or, P2V fails for a certain machine every time. If you’ve searched many TechNet blogs or forums for answers you have probably come to one conclusion: you’re going to have to run a trace to collect the required information.

How do I capture a trace? Armed with DbgView (available from Sysinternals.com) and a number of registry modifications, followed by service restarts on each involved machine, you’re ready to begin. Problem is, configuring a server for tracing is time consuming, tedious, and prone to human error. I’ve worked to alleviate your pain.

Easy? Seriously?

True. You need two files on each server you wish to run the trace on. The process is automated, requires very little input, and works. I’ll skip how it works other than to say it performs the work in Cheng’s article for you. Manual steps are below. If you would like to download a zip file with everything ready click the button below.

Instructions

1. DOWNLOAD SCTrace from the 'Download' button above.

2. SAVE ‘SCTrace_x.x.zip to a directory near the root of C: such as ‘C:\Temp’. (Remaining instructions assume this is where you saved the file...)

3. EXTRACT 'sctrace.zip'. By default this will create a folder named 'SCTrace_x.x' in 'C:\Temp'

4. From an ELEVATED command prompt change to the directory where the files are extracted (C:\Temp\SCTrace_x.x) and type sctrace.cmd

5. FOLLOW the prompts in the COMMAND WINDOW at all times

Tips for Successful Tracing

Follow the instructions in the command prompt. Remember that the goal is to capture the issue while is is reproduced. If the problem is between a Host and the SCVMM Server, run this same script on both machines at the SAME TIME. We need both ends of the conversation to figure out what is going on. The script will provide an opportunity to get things kicked off on all servers then start all the traces at once.

Disclaimer

Every effort has been made to accommodate various environments, while at the same time keeping the length of the script to a minimum. This script may not work if you have a locked down system. This script is provided as is. That said, I would love to hear what you think of it. Corrections appreciated as well. Check back for version updates.
