What is CMTrace SCCM LOG Viewer
CMTrace SCCM LOG Viewer is a tool from Microsoft to view their “*.log” files from different tools – Microsoft Deployment Toolkit (MDT), Microsoft Software Center Configuration Manager (SCCM), DISM and many others. Though, mostly for SCCM as it is part of “Configuration Manager Tools”. Information about the application and usage can be found in CMTrace Microsoft Docs.
Several Updates: As of SCCM CB 1806, CMTrace is installing with SCCM Client by default to: %WinDir%\CCM\CMTrace.exe.
As of SCCM CB 1906, CMTrace SCCM Log Viewer is deprecated and replaced by “Support Center OneTrace” – read more on Microsoft Docs. You can install OneTrace with “Support Center”. The setup file is located on the site server in:
After installation, by default, the application will be in:
C:\Program Files (x86)\Configuration Manager Support Center\CMPowerLogViewer.exe
The only problem with OneTrace – you cannot use it in WinPE (as is), since it is using Windows Presentation Foundation (WPF), unlike CMTrace.
Reading SCCM LOGs with CMTrace SCCM LOG Viewer
The LOGs are not easy read and contain amounts of valuable information. CMTrace can help viewing the LOGs by arranging all the information in simple GUI. When reading LOGs, the application might show you red and yellow lines. This does not mean that there is a real problem – everything is a matter of context.
CMTrace marks every line that has a word “Error” / “Failed” in it with red color. Same goes for yellow color with “Could not”. When something is failing, in most cases the task will execute again and it will succeed. Therefore, read the LOGs carefully and try to understand the meaning of the message.
