🚀 Quick Start Guide

For New Users (Recommended)

python3 logboss.py --interactive

For Production Environments

# Create commands file
echo -e "systemctl\nreboot\nshutdown\nsudo" > commands.txt

# Run with optimal settings
python3 logboss.py --command-file commands.txt --workers 8 --output production_scan.csv

For Maximum Performance

# Create commands file
echo -e "systemctl\nreboot\nshutdown" > commands.txt

# Run ultra-fast parser
python3 ulogboss.py commands.txt /var/log

---

📁 Output Format

All parsers generate CSV files with the following structure:

timestamp,command,file_path,log_line
2024-01-15 10:30:45,systemctl,/var/log/syslog,"Jan 15 10:30:45 server systemctl restart nginx"
2024-01-15 10:31:02,reboot,/var/log/auth.log,"Jan 15 10:31:02 server reboot requested by admin"

Columns

• timestamp: Extracted timestamp from log line
• command: Matched command(s) separated by |
• file_path: Full path to the source log file
• log_line: Complete original log line

🔍 Troubleshooting

Common Issues

Permission Denied

# Run with appropriate permissions
sudo python3 logboss.py --log-dir /var/log

# Or change log directory ownership
sudo chown -R $USER:$USER /path/to/logs

Memory Issues

# Reduce worker threads
python3 logboss.py --workers 2

# Use ultra-optimized version
python3 ulogboss.py commands.txt /var/log

No Results Found

1. Check if log directory exists and contains files
2. Verify command spelling in commands file
3. Ensure log files have proper extensions (.log, .gz, .bz2)
4. Run with --verbose flag to see detailed processing info

Performance Issues

• Slow processing: Use ulogboss.py for maximum speed
• High memory usage: Reduce workers or use ulogboss.py
• CPU not fully utilized: Increase workers in logboss.py
