Question

当我从Windows命令行运行log.cmd时，我从xperf收到错误，指出*.etl文件已存在。我知道其他进程也使用Windows ETL，并且gpuview使用xperf来跟踪事件，它在某种意义上“碰撞”。尽管如此，我还是通过再次运行log.cmd来获得大量合并的ETL文件。

我讨厌使用cmd并尝试使用cygwin bash做同样的事情。我得到类似的错误，但除了DXCstate.etl，我没有看到任何其他错误。

我正在使用admin privelges运行终端，log.cmd拥有755个权限。

$ ./log.cmd

如果查看log.cmd，您会看到每个记录器都与文件名相关联。例如，我们有这一行：

“％~dp0”.. \ Xperf -start DxcLogger -on％TRACE_DXC_MIN %% TRACE_LARGE_BUFFERS％-f DXC.etl

如果你可以“当该文件已存在时无法创建文件”错误，那么这意味着DXC.etl已经存在，这意味着以前的log.cmd调用没有干净地退出并且没有停止记录到该文件。您可能已使用Ctrl + C取消了批处理文件。它与Process Explorer或资源监视器不冲突，因为它们不会特别使用DXC.etl。

因此，重启机器以恢复良好状态，并警惕在工作中停止log.cmd。

或者，只需停止使用log.cmd即可。请改用wprui.exe。有关详细信息，请参阅此博客文章：

使用cygwin进行Gpuview日志记录不起作用
