@AvaIon 你好! 我是Dosu。我是一个能帮助你解决问题、回答疑问并成为贡献者的机器人。在等待人类维护者的过程中，我会尽力帮助你。

When Kyanos fails to capture MySQL queries, there are several potential reasons and troubleshooting steps you can consider:

1. Kernel BTF Configuration: Ensure that BTF (BPF Type Format) is enabled in your kernel. You can check this with:

   grep CONFIG_DEBUG_INFO_BTF "/boot/config-$(uname -r)"

   If BTF is not enabled, you may need to download the necessary BTF file and use the --btf option when starting Kyanos ^[1].

2. Network and System Permissions: Verify that Kyanos has the necessary permissions to access network interfaces and system resources. Running Kyanos with sudo should typically provide the required permissions.

3. MySQL Version Compatibility: While there is no specific information on compatibility issues with MySQL 8.0.39, ensure that your MySQL version is supported by Kyanos. Compatibility issues might arise if there are protocol changes in newer MySQL versions.

4. Check for Errors and Logs: Review any error messages or logs generated by Kyanos for clues about what might be going wrong. This can help identify if there are specific protocol errors or unexpected packet structures.

5. Ensure Correct Command Usage: Double-check the command you are using to start Kyanos and ensure it is correctly configured to monitor MySQL traffic. The watch command should be set up to capture the appropriate network traffic.

If these steps do not resolve the issue, further investigation into the specific environment and configuration might be necessary.
