# Plugin Logging

> Emit logs from your plugin with the SDK's plugin_logger_handler, visible during remote debugging and in daemon container logs

While developing or debugging a plugin, you often want to log what your code is doing.

The plugin SDK provides a handler for Python's standard `logging` library. Add it to your logger to write any string to both the standard output during remote debugging and the plugin daemon container logs (Community Edition only).

## Example

Import `plugin_logger_handler` and add it to your logger. The following example shows a tool plugin.

```python theme={null}
from collections.abc import Generator
from typing import Any
from dify_plugin import Tool
from dify_plugin.entities.tool import ToolInvokeMessage


# Import logging and custom handler
import logging
from dify_plugin.config.logger_format import plugin_logger_handler

# Set up logging with the custom handler
logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)
logger.addHandler(plugin_logger_handler)


class LoggerDemoTool(Tool):
    def _invoke(self, tool_parameters: dict[str, Any]) -> Generator[ToolInvokeMessage]:

        # Log messages with different severity levels
        logger.info("This is an INFO log message.")
        logger.warning("This is a WARNING log message.")
        logger.error("This is an ERROR log message.")

        yield self.create_text_message("Hello, Dify!")
```
