## 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
# Advanced features
compression: true # Enable log compression
correlation_id: true # Enable correlation IDs
performance_monitoring: true # Enable performance tracking
cleanup_old_logs: true # Enable automatic cleanup
cleanup_days: 30 # Days to keep logs
# Metadata
include_hostname: true # Include hostname in logs
include_version: true # Include software version in logs
```
## 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)
daemon:
logging:
level: "INFO"
format: "json"
file: "/var/log/apt-ostree/daemon.log"
max_size: "100MB"
max_files: 5
# Enhanced configuration (recommended)
daemon:
logging:
level: "INFO"
format: "json"
file: "/var/log/apt-ostree/daemon.log"
max_size: "100MB"
max_files: 5
rotation_strategy: "size"
compression: true
correlation_id: true
performance_monitoring: true
cleanup_old_logs: true
cleanup_days: 30
include_hostname: true
include_version: true
```
