## Configuration
|
||||
|
||||
### Basic Logging Configuration
|
||||
|
||||
```yaml
|
||||
daemon:
|
||||
logging:
|
||||
level: "INFO" # Log level (DEBUG, INFO, WARNING, ERROR, CRITICAL)
|
||||
format: "json" # Output format (json, text)
|
||||
file: "/var/log/apt-ostree/daemon.log" # Log file path
|
||||
max_size: "100MB" # Maximum log file size
|
||||
max_files: 5 # Number of backup files to keep
|
||||
```
|
||||
|
||||
### Advanced Logging Configuration
|
||||
|
||||
```yaml
|
||||
daemon:
|
||||
logging:
|
||||
# Basic settings
|
||||
level: "INFO"
|
||||
format: "json"
|
||||
file: "/var/log/apt-ostree/daemon.log"
|
||||
max_size: "100MB"
|
||||
max_files: 5
|
||||
|
||||
# Rotation strategy
|
||||
rotation_strategy: "size" # 'size', 'time', 'hybrid'
|
||||
rotation_interval: 1 # For time-based rotation
|
||||
rotation_unit: "D" # D=days, H=hours, M=minutes
|
||||

|
||||
```
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Basic Logging
|
||||
|
||||
```python
|
||||
from utils.logging import AptOstreeLogger
|
||||
|
||||
# Initialize logger
|
||||
config = {'daemon': {'logging': {...}}}
|
||||
logger_manager = AptOstreeLogger(config)
|
||||
logger = logger_manager.get_logger('my-component')
|
||||
|
||||
# Basic logging
|
||||
logger.info("Operation completed successfully")
|
||||
logger.warning("Resource usage is high")
|
||||
logger.error("Failed to connect to database")
|
||||
```
|
||||
|
||||
### Structured Logging with Extra Fields
|
||||
|
||||
```python
|
||||
# Log with additional context
|
||||
logger.log_with_fields(logging.INFO, "Package installation started",
|
||||
package="firefox", version="115.0", user="root")
|
||||
```
|
||||
|
||||
### Performance Logging
|
||||
|
||||
```python
|
||||
import time
|
||||
|
||||
# Track operation performance
|
||||
start_time = time.time()
|
||||
# ... perform operation ...
|
||||
duration = time.time() - start_time
|
||||
logger.log_performance("package_install", duration, package="firefox")
|
||||
```
|
||||
|
||||
### Transaction Logging
|
||||
|
||||
```python
|
||||
# Log transaction events
|
||||
transaction_id = "tx-12345"
|
||||
logger.log_transaction(transaction_id, "started", operation="install")
|
||||
logger.log_transaction(transaction_id, "completed", operation="install", success=True)
|
||||
```
|
||||
|
||||
## Log Rotation Strategies
|
||||
|
||||
### 1. Size-based Rotation (Default)
|
||||
|
||||
```yaml
|
||||
rotation_strategy: "size"
|
||||
max_size: "100MB"
|
||||
max_files: 5
|
||||
```
|
||||
|
||||
- Rotates when log file reaches specified size
|
||||
- Keeps specified number of backup files
|
||||
- Automatically compresses old files
|
||||
|
||||
### 2. Time-based Rotation
|
||||
|
||||
```yaml
|
||||
rotation_strategy: "time"
|
||||
rotation_interval: 1
|
||||
rotation_unit: "D" # Daily rotation
|
||||
max_files: 7 # Keep 7 days of logs
|
||||
```
|
||||
|
||||
- Rotates at specified time intervals
|
||||
- Supports days (D), hours (H), minutes (M)
|
||||
- Useful for daily/weekly log management
|
||||
|
||||
### 3. Hybrid Rotation
|
||||
|
||||
```yaml
|
||||
rotation_strategy: "hybrid"
|
||||
max_size: "50MB" # Smaller size for more frequent rotation
|
||||
max_files: 10 # More backup files
|
||||
```
|
||||
|
||||
- Combines size and time-based strategies
|
||||
- More frequent rotation for better log management
|
||||
- Useful for high-volume logging scenarios
|
||||
|
||||
## Log File Structure
|
||||
|
||||
### Current Log File
|
||||
- `/var/log/apt-ostree/daemon.log` - Active log file
|
||||
|
||||
### Rotated Log Files
|
||||
- `/var/log/apt-ostree/daemon.log.1.gz` - Most recent backup (compressed)
|
||||
- `/var/log/apt-ostree/daemon.log.2.gz` - Second most recent backup
|
||||
- `/var/log/apt-ostree/daemon.log.3.gz` - Third most recent backup
|
||||
- etc.
|
||||
|
||||
## Log Entry Format
|
||||
|
||||
### JSON Format Example
|
||||
|
||||
```json
|
||||
{
|
||||
"timestamp": "2024-01-15T10:30:00.123456",
|
||||
"level": "INFO",
|
||||
"logger": "apt-ostree.daemon",
|
||||
"message": "Package installation completed",
|
||||
"module": "daemon",
|
||||
"function": "install_packages",
|
||||
"line": 123,
|
||||
"process_id": 12345,
|
||||
"thread_id": 140123456789888,
|
||||
"correlation_id": "550e8400-e29b-41d4-a716-446655440000",
|
||||
"uptime": 3600.5,
|
||||
"request_count": 150,
|
||||
"hostname": "particle-os",
|
||||
"version": "1.0.0",
|
||||
"package": "firefox",
|
||||
"version": "115.0",
|
||||
"user": "root"
|
||||
}
|
||||
```
|
||||
|
||||
### Text Format Example
|
||||
|
||||
```
|
||||
2024-01-15 10:30:00,123 - apt-ostree.daemon - INFO - [550e8400-e29b-41d4-a716-446655440000] [uptime=3600.50s] Package installation completed [package=firefox version=115.0 user=root]
|
||||
```
|
||||
|
||||
## Log Management Commands
|
||||
|
||||
### Get Log Statistics
|
||||
|
||||
```python
|
||||
stats = logger_manager.get_log_stats()
|
||||
print(f"Current log size: {stats['current_log_size']} bytes")
|
||||
print(f"Total log files: {stats['total_log_files']}")
|
||||
print(f"Oldest log age: {stats['oldest_log_age']} seconds")
|
||||
```
|
||||
|
||||
### Clean Up Old Logs
|
||||
|
||||
```python
|
||||
# Remove logs older than 30 days
|
||||
logger_manager.cleanup_old_logs(days=30)
|
||||
```
|
||||
|
||||
### Validate Log Entries
|
||||
|
||||
```python
|
||||
from utils.logging import LogValidator
|
||||
|
||||
validator = LogValidator()
|
||||
is_valid = validator.validate_log_entry(log_entry)
|
||||
```
|
||||
|
||||
## Systemd Integration
|
||||
|
||||
The enhanced logging system integrates seamlessly with systemd:
|
||||
|
||||
```bash
|
||||
# View logs in systemd journal
|
||||
journalctl -u apt-ostreed -f
|
||||
|
||||
# View logs with JSON format
|
||||
journalctl -u apt-ostreed -o json
|
||||
|
||||
# Filter logs by correlation ID
|
||||
journalctl -u apt-ostreed CORRELATION_ID=550e8400-e29b-41d4-a716-446655440000
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Log Rotation Performance
|
||||
- Compression is done asynchronously to avoid blocking
|
||||
- File operations use efficient buffering
|
||||
- Rotation triggers are optimized to minimize overhead
|
||||
|
||||
### Memory Usage
|
||||
- Log entries are streamed to avoid memory accumulation
|
||||
- Structured logging uses efficient JSON serialization
|
||||
- Performance metrics are tracked with minimal overhead
|
||||
|
||||
### Disk Usage
|
||||
- Automatic compression reduces disk usage by 70-90%
|
||||
- Configurable retention policies prevent disk space issues
|
||||
- Log statistics help monitor disk usage
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Log Rotation Not Working**
|
||||
- Check file permissions on log directory
|
||||
- Verify disk space availability
|
||||
- Check rotation configuration settings
|
||||
|
||||
2. **High Disk Usage**
|
||||
- Reduce `max_files` setting
|
||||
- Enable compression
|
||||
- Use automatic cleanup
|
||||
- Consider time-based rotation
|
||||
|
||||
3. **Performance Issues**
|
||||
- Increase log level to reduce verbosity
|
||||
- Use size-based rotation for high-volume logging
|
||||
- Monitor log statistics for bottlenecks
|
||||
|
||||
### Debug Mode
|
||||
|
||||
Enable debug logging for troubleshooting:
|
||||
|
||||
```yaml
|
||||
daemon:
|
||||
logging:
|
||||
level: "DEBUG"
|
||||
format: "text" # More readable for debugging
|
||||
```
|
||||
|
||||
## Best Practices
|
||||
|
||||
1. **Log Levels**
|
||||
- Use DEBUG for development and troubleshooting
|
||||
- Use INFO for normal operations
|
||||
- Use WARNING for recoverable issues
|
||||
- Use ERROR for operation failures
|
||||
- Use CRITICAL for system failures
|
||||
|
||||
2. **Rotation Strategy**
|
||||
- Use size-based rotation for high-volume logging
|
||||
- Use time-based rotation for predictable log management
|
||||
- Use hybrid rotation for optimal balance
|
||||
|
||||
3. **Retention Policy**
|
||||
- Keep enough logs for troubleshooting
|
||||
- Balance retention with disk space
|
||||
- Use compression to extend retention
|
||||
|
||||
4. **Performance Monitoring**
|
||||
- Log performance metrics for critical operations
|
||||
- Use correlation IDs to track related operations
|
||||
- Monitor log statistics regularly
|
||||
|
||||
## Migration from Basic Logging
|
||||
|
||||
The enhanced logging system is backward compatible. Existing configurations will continue to work with default values for new features:
|
||||
|
||||
```yaml
|
||||
# Old configuration (still works)
|
||||
