Performance Monitor Does Not Automatically Append the .log File Extension to a Log File

• Microsoft Windows NT Server versions 3.51, 4.0
• Microsoft Windows NT Workstation versions 3.51, 4.0
• Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When you try to create a performance monitor log file in Performance Monitor after choosing Save As Log, the .log file extension is not automatically appended to the name of the file. For example, the file that is created has no file extension and appears as an unknown file type, and you cannot open this file in Performance Monitor unless it has the .log extension.

RESOLUTION

To work around this problem, use any of the following methods:

• Manually add the .log extension to the file name before saving or starting the log.



• Add the .log extension to the unknown file after it has been created.



• When using the data from box to view a log, type *.* in the File Name box so that all files are displayed. Select the log file that does not have the .log extension.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
