A Proper Log File Reader – A Must for Effective Troubleshooting
Having the right tool for reading log files is essential for efficient troubleshooting.
When I started my IT career, one of the first systems I was introduced to was Microsoft System Center Configuration Manager (SCCM/ConfigMgr). It quickly became clear that a proper log file reader was indispensable.
Thankfully, Microsoft included CMTrace with the Configuration Manager installation package. Since then, it has remained my go-to tool for log file analysis due to its simplicity and effectiveness.
Enter OneTrace – A Modern Alternative
In 2019, Microsoft released OneTrace as a preview – a modern replacement with several enhancements:
- Tabbed view for working with multiple logs
- Improved search functionality
- Scrollbar hints for error and warning locations
- Better performance with large files
You can find more details about OneTrace on learn.microsoft.com.
In October 2022, Microsoft updated their documentation to officially position OneTrace as the new feature-rich viewer, alongside CMTrace.
However, OneTrace isn’t without limitations. Since it relies on .NET and Windows Presentation Foundation (WPF), it’s not usable in WinPE environments. Because of this, it should be seen as a supplement, not a full replacement for CMTrace.
Personally, that’s not a problem for me – but I’ll admit I still use CMTrace most of the time. It’s lightweight, portable, and just gets the job done.
Download, Install, and Use
You can download both CMTrace and OneTrace from the Configuration Manager Current Branch download package. It’s available as a free evaluation and doesn’t require a license key – and both tools can be used beyond the evaluation period at no cost.
CMTrace
After extracting the download package, locate the file at:..\cd.retail.LN\SMSSETUP\TOOLS\CMTrace.exe
💡 Tip: Copy CMTrace.exe to C:\Windows\System32 for easy access from the command line.
OneTrace
The installer is part of the Support Center package:..\cd.retail.LN\SMSSETUP\TOOLS\SupportCenter\SupportCenterInstaller.msi
Once installed, you can launch OneTrace directly from the Start menu.
Final Thoughts
Over the years, I’ve saved countless hours thanks to simple, reliable tools like these. They require almost no effort to integrate into your workflow – yet they make a big difference.
Still using Notepad++ or even plain Notepad for log file analysis?
Maybe it’s time to upgrade. 😊
