[LTTng学习之旅]------翻车-在WSL2中尝试使用LTTng

一切都看起来很顺利，我使用apt安装了各种包。
然后尝试了一下：

lttng list --kernel
Error: Unable to list kernel events: Kernel tracer not available

然后搜索了一下：
https://github.com/microsoft/WSL/issues/6137

@trgibeau @ivberg-zz you mentioned WSL2 in https://tracingsummit.org/ts/2019/WPA/

I successfully built https://github.com/lttng/lttng-modules#building using https://github.com/microsoft/WSL2-Linux-Kernel and ran the lttng daemon: https://lttng.org/docs/#doc-tracing-the-linux-kernel but I always get ‘Kernel tracer not available’ (a) the modules don’t get loaded by the daemon as described in the docs, (b) when loading them manually it doesn’t make a difference, © neither does building them right into the kernel

Have you tried this internally? Should it work?

看来是老问题了，如果想弄可能需要比较麻烦的操作。’‘

这个还是留给微软自己去弄吧。 good。

对于性能分析来讲，有的要开内核选项，有的要开服务，有的要加载模块。
麻烦。。==
