How to print more logs when agent running?

[Guanwei1989]

The default log is too less, I want to see more detail logs, such as prompt, completions, etc. is there any way can do it?

Use the EVENT_LOGGER_NAME and TRACE_LOGGER_NAME in the Core. It contains all the model client call events.

I tried use TRACE_LOGGER_NAME and EVENT_LOGGER_NAME according to guideline, but it doesn't work.

import logging

from autogen_core import TRACE_LOGGER_NAME

logging.basicConfig(level=logging.WARNING)
logger = logging.getLogger(TRACE_LOGGER_NAME)
logger.setLevel(logging.DEBUG)

import logging
from dataclasses import dataclass

@dataclass
class MyEvent:
    timestamp: str
    message: str

class MyHandler(logging.Handler):
    def __init__(self) -> None:
        super().__init__()

    def emit(self, record: logging.LogRecord) -> None:
        try:
            # Use the StructuredMessage if the message is an instance of it
            if isinstance(record.msg, MyEvent):
                print(f"Timestamp: {record.msg.timestamp}, Message: {record.msg.message}")
        except Exception:
            self.handleError(record)

logger = logging.getLogger(EVENT_LOGGER_NAME)
logger.setLevel(logging.INFO)
my_handler = MyHandler()
logger.handlers = [my_handler]

The output still as following:

Enter a message (type 'exit' to leave): What is the capital of France
---------- user ----------
What is the capital of France
---------- weather_agent ----------
The capital of France is Paris.

I want to see more detail to understand what happening in the running process, such as the prompt and GAI completion, and how to make decision for handoff in multi-agents?
