# Get the custom logger we will use for the example.
custom_logger = get_custom_logger()

# Configure Agno to use our custom logger. It will be used for all logging.

# Every use of the logging function in agno.utils.log will now use our custom logger.

# Now let's setup an Agent and run it.
# All logging coming from the Agent will use our custom logger.
