INTRODUCTION
This article describes how to turn on TraceLevel logging in Microsoft Operations Manager (MOM) 2005.



MORE INFORMATION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

By default, logging is turned on in MOM 2005. The logging level is controlled by the TraceLevel DWORD value. The TraceLevel DWORD value is located in the following registry subkey:

When you perform a new installation of MOM, the TraceLevel value is set to 1. When the TraceLevel value is set to 1, only errors are logged. However, if you perform an upgrade, the previous TraceLevel value is retained.

Note In MOM 2005, any changes to the TraceLevel value are dynamic. Therefore, you do not have to restart the computer for these changes to take effect.

Important For performance reasons, we do not recommend that you use TraceLevel 9 in production.

The following log files contain detailed information about the error message. The following log files are stored in the \TEMP\Microsoft Operations Manager folder on the MOM Management Server.

You can use the MOM Log Viewer (MOMLogViewer.exe) utility to view these log files. The MOM Log Viewer utility is available in the MOM 2005 Resource Kit. To download the MOM 2005 Resource Kit, visit the following Microsoft Web site:

Note When you perform a new installation of MOM 2005, the MOM 2005 Reporting component is logged to the MOMServer.log file. The MOM Console information is also logged to the MOMServer.log file. The MOMServer.log file is located in the logged on users Temp folder. The following folder is an example of a logged on users Temp folder:
