Output SARIF diagnostics to the specified file or directory. For more information, see Structured SARIF Diagnostics.
Syntax
/experimental:logfilename
/experimental:logdirectoryname\
Arguments
filename
The output file for SARIF diagnostics. The compiler automatically adds the .sarif extension to filename. The space between /experimental:log and filename is optional. Use double quotes around paths containing spaces. Both relative and absolute paths are supported.
directoryname\
The output directory for SARIF diagnostics (for example, /experimental:log sarif_output\). Remember to add the trailing backslash (\) to indicate it's a directory. Each source file name forms the base name for each SARIF file saved in the directory. The compiler automatically adds the .sarif extension to each file name. The space between /experimental:log and directoryname\ is optional. Use double quotes around paths containing spaces. Both relative and absolute paths are supported.
Remarks
This option is available starting in Visual Studio 2022 version 17.8.
Diagnostics are also output as text to the console as usual.

cl /experimental:log mySarifInfo main.cpp
The following command produces SARIF information for the entire compilation and saves it in the sarif_output directory in the files main.sarif and other.sarif:
cl /experimental:log sarif_output\ main.cpp other.cpp
