    delaycompress
    notifempty
    create 0640 www-data www-data

        php artisan queue:restart
    endscript
}

Log Analysis​

Common Queries​

# Error count
grep -c "ERROR" laravel.log

# Errors by date
grep "ERROR" laravel.log | cut -d' ' -f1 | sort | uniq -c

# Recent errors
tail -n 100 laravel.log | grep "ERROR"

Best Practices​

  1. Structured Logging: Use JSON format
  2. Context Information: Include request ID, user ID
  3. Sensitive Data: Never log passwords, tokens
  4. Log Levels: Use appropriate levels
  5. Rotation: Regular log rotation
  6. Monitoring: Monitor log file sizes
  7. Retention: Clear retention policy
