我们创建QLOG是为了更好地了解Windows ETW。QLOG为Windows上的进程创建事件提供了丰富的日志记录。我们已经停止了对QLOG的开发，因为与此同时，一些免费工具已经发布，它们使用ETW进行遥测，并且比QLOG做得更好。好奇吗？请查看Nextron的Aurora Agent。

Qlog是什么

QLOG不使用API钩子，也不需要在目标系统上安装驱动程序，QLOG仅使用ETW来获取其遥测数据。目前QLOG仅支持"进程创建"事件。QLOG作为Windows服务运行，但如果您希望直接将丰富的事件流式传输到控制台，也可以以控制台模式运行。

它是如何工作的

QLOG从ETW读取数据，丰富事件，并将丰富后的事件写入事件通道"QLOG"。它创建并使用名为"QMonitor"的新事件源来写入Windows事件日志。

开发与许可证

QLOG由threathunters.io社区开发，一旦达到生产级成熟度，将开放源代码。

使用与安装

QLOG需要安装.NET Framework >=4.7.2。

要以交互式控制台模式运行，只需运行

qlog.exe

要安装/卸载为Windows服务，运行：

#安装服务
qlog.exe -i 

#卸载服务
qlog.exe -u
