symbols
Enables and configures symbol decoding support.
xperf -i <trace file>… [-o output] -symbols [cacheonly] [verbose]
Parameters
cacheonly
This option speeds symbol decoding for traces with many binary images that lack symbol files after all interesting symbol files have been transcoded.
verbose
Verbose mode. Prints symbol paths and version information. For more information, see Loading Symbols.
Symbol decoding support uses the environment variables in the following table for further configuration of SymCache.
_NT_SYMCACHE_PATH |
Specifies the path to the local SymCache directory. By default, \SymCache is used. |
Note
For symbol decoding, the trace must be a kernel trace (or a user trace processed in conjunction with a kernel trace) that has the PROC_THREAD+LOADER kernel flags enabled and that has been stopped and merged with -d or with -merge on the computer on which it was taken. Xperf performs a special image identification process during its custom trace merge that enables symbol decoding.
Remarks
If this action is not specified on the command line, symbol decoding is disabled.
