Is there any method to run perf under WSL?
Feb 15
When I wanted to run perf under WSL, I met the follow question:
WARNING: perf not found for kernel 4.4.0-18362
You may need to install the following packages for this specific kernel:
linux-tools-4.4.0-18362-Microsoft
linux-cloud-tools-4.4.0-18362-Microsoft
You may also want to install one of the following packages to keep up to date:
linux-tools-Microsoft
linux-cloud-tools-Microsoft
But I can't find packages called linux-tools-4.4.0-18362-Microsoft or linux-cloud-tools-4.4.0-18362-Microsoft. I guess the package names are generated automatically.
I also tried to use perf in docker container. However, docker container use the same kernel as the hosts.

I heard that perf can be used in WSL2. But after I upgraded to WSL2, it shows the similar error message:
WARNING: perf not found for kernel 4.19.84-microsoft
You may need to install the following packages for this specific kernel:
linux-tools-4.19.84-microsoft-standard linux-cloud-tools-4.19.84-microsoft-standardYou may also want to install one of the following packages to keep up to date:

Because WSL2 uses custom Linux kernel. Its source code can be found here microsoft/WSL2-Linux-Kernel. We have to compile perf tools from it.
Procedure
- Install required build packages. If you are using Ubuntu in WSL2 this is the required command:
sudo apt install build-essential flex bison libssl-dev libelf-dev
- Clone the WSL2 Linux kernel repository:
git clone --depth=1 https://github.com/microsoft/WSL2-Linux-Kernel.git
- Go to perf folder and compile it:
cd WSL2-Linux-Kernel/tools/perf
make
perf executable file will be in that folder.
