# Description

Earlier, we used [`Carbonite
SDK`](https://docs.omniverse.nvidia.com/kit/docs/carbonite/latest/api/dir_carb_logging.html)
to log directly. However, this has limited functionalities compared to
[`omni.log`](https://docs.omniverse.nvidia.com/kit/docs/carbonite/latest/api/namespace_omni__log.html)
in Omniverse. Using `omni.log`, you can fine-grain the channels and
print levels better.

Link to omni.log documentation:
https://docs.omniverse.nvidia.com/kit/docs/carbonite/latest/docs/omni.log/Logging.html

This MR migrates all `carb` references to the new API.

## Type of change

- Bug fix (non-breaking change which fixes an issue)
- Breaking change (fix or feature that would cause existing
functionality to not work as expected)
