PropagateHandler

The PropagateHandler bridges Logly messages back to Python's standard logging module.

Usage

from logly import logger
from logly.integrations.propagate import PropagateHandler

# Add PropagateHandler as a sink
logger.add(PropagateHandler(), format="{message}")

Custom Logger Name

logger.add(
    PropagateHandler(name="myapp"),
    format="{message}",
    level="INFO",
)

How It Works

• Routes all Logly messages through Python's standard logging module
• Automatically maps Logly levels to stdlib levels
• Useful when you need to feed Logly output into existing monitoring tools that hook into stdlib logging

Level Mapping

Logly Level	stdlib Level
TRACE, DEBUG	DEBUG
INFO, NOTICE, SUCCESS	INFO
WARNING, WARN	WARNING
ERROR, FAIL	ERROR
CRITICAL, FATAL	CRITICAL
