I didn't see clear examples on how the logging works. This is an example error message:

CRITICAL:root:Failed to import "runtime_client" cpp file. Error loading shared library libzstd.so.1: No such file or directory (needed by /app/runtime_client.cpython-312-x86_64-linux-musl.so)

I would love to standardize this after getting some guidance.
