FAQ

No Output After Running kyanos watch

Check if you see a log like this when starting Kyanos:

find btf file exactly failed, try to find a lower version btf file...

If so, this might be due to a missing BTF file on your system. You can manually download the BTF file matching your kernel version from mirrors.openanolis.cn or btfhub-archive, and then specify the downloaded BTF file using the --btf option when starting Kyanos.
