# Logging Implementation Summary
|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### 1. Core Logging Infrastructure (`src/infrastructure/logging/`)
|
||||
|
||||
- **`logger.py`**: Main logging configuration module
|
||||
|
||||
- `setup_logging()`: Configures both console and file handlers
|
||||
- `get_logger()`: Retrieves logger instances for specific modules
|
||||
- Follows Python logging best practices with proper formatters
|
||||
|
||||
- **`uvicorn_config.py`**: Uvicorn-specific logging configuration
|
||||
|
||||
- Custom logging configuration dictionary for uvicorn
|
||||
- Ensures uvicorn logs are captured in both console and file
|
||||
- Configures multiple loggers (uvicorn, uvicorn.error, uvicorn.access, aniworld)
|
||||
|
||||
- **`__init__.py`**: Package initialization
|
||||
- Exports public API: `setup_logging`, `get_logger`, `get_uvicorn_log_config`
|
||||
|
||||
### 2. FastAPI Integration
|
||||
|
||||
Updated `src/server/fastapi_app.py` to:
|
||||
|
||||
- Import and use the logging infrastructure
|
||||
- Call `setup_logging()` during application startup (in `lifespan()`)
|
||||
- Replace all `print()` statements with proper logger calls
|
||||
- Use lazy formatting (`logger.info("Message: %s", value)`)
|
||||
|
||||
### 3. Startup Scripts
|
||||
|
||||
- **`run_server.py`**: Python startup script
|
||||
|
||||
- Uses the custom uvicorn logging configuration
|
||||
- Recommended way to start the server
|
||||
|
||||
- **`start_server.sh`**: Bash startup script
|
||||
- Wrapper around `run_server.py`
|
||||
- Made executable with proper shebang
|
||||
|
||||
### 4. Documentation
|
||||
|
||||
- **`docs/logging.md`**: Comprehensive logging guide
|
||||
- How to run the server
|
||||
- Log file locations
|
||||
- Log format examples
|
||||
- Troubleshooting guide
|
||||
- Programmatic usage examples
|
||||
|
||||

|
||||
|
||||
## How to Use
|
||||
|
||||
### Starting the Server
|
||||
|
||||
**Recommended:**
|
||||
|
||||
```bash
|
||||
conda run -n AniWorld python run_server.py
|
||||
```
|
||||
|
||||
**Alternative:**
|
||||
|
||||
```bash
|
||||
./start_server.sh
|
||||
```
|
||||
|
||||
**View logs in real-time:**
|
||||
|
||||
```bash
|
||||
tail -f logs/fastapi_app.log
|
||||
```
|
||||
|
||||
### In Code
|
||||
|
||||
```python
|
||||
from src.infrastructure.logging import get_logger
|
||||
|
||||
logger = get_logger(__name__)
|
||||
|
||||
logger.info("Message: %s", value)
|
||||
logger.warning("Warning: %s", warning_msg)
|
||||
logger.error("Error occurred", exc_info=True)
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
Set log level via environment variable or `.env` file:
|
||||
|
||||
```bash
|
||||
export LOG_LEVEL=INFO # or DEBUG, WARNING, ERROR
|
||||
```
|
||||
|
||||
## Features
|
||||
|
||||
✅ **Console logging**: Colored, easy-to-read format
|
||||
✅ **File logging**: Detailed with timestamps and logger names
|
||||
✅ **Automatic log directory creation**: `logs/` created if missing
|
||||
✅ **Uvicorn integration**: All uvicorn logs captured
|
||||
✅ **Multiple loggers**: Different loggers for different modules
|
||||
✅ **Configurable log level**: Via environment variable
|
||||
✅ **Proper formatting**: Uses lazy formatting for performance
|
||||
✅ **Startup/shutdown logging**: Clear application lifecycle logs
|
||||
✅ **Error tracebacks**: Full exception context with `exc_info=True`
|
||||
|
||||
## Files Created/Modified
|
||||
|
||||
### Created:
|
||||
|
||||
- `src/infrastructure/logging/logger.py`
|
||||
- `src/infrastructure/logging/uvicorn_config.py`
|
||||
- `src/infrastructure/logging/__init__.py`
|
||||
- `run_server.py`
|
||||
- `start_server.sh`
|
||||
- `docs/logging.md`
|
||||
- `docs/logging_implementation_summary.md` (this file)
|
||||
|
||||
### Modified:
|
||||
|
||||
- `src/server/fastapi_app.py`: Integrated logging throughout
|
||||
|
||||
## Testing
|
||||
|
||||
The implementation has been tested and verified:
|
||||
|
||||
- ✅ Log file created at `logs/fastapi_app.log`
|
||||
- ✅ Startup messages logged correctly
|
||||
- ✅ Application configuration loaded and logged
|
||||
- ✅ Uvicorn logs captured
|
||||
- ✅ File watching events logged
|
||||
- ✅ Shutdown messages logged
|
||||
|
||||
## Next Steps
|
||||
|
||||
Consider adding:
|
||||
|
||||
1. **Log rotation**: Use `RotatingFileHandler` to prevent log files from growing too large
|
||||
2. **Structured logging**: Use `structlog` for JSON-formatted logs
|
||||
3. **Log aggregation**: Send logs to a centralized logging service
|
||||
4. **Performance monitoring**: Add timing logs for slow operations
|
||||
5. **Request logging middleware**: Log all HTTP requests/responses
