+echo "------------"
+echo "To test the full eBPF integration:"
+echo ""
+echo "a) Run with root privileges for full eBPF access:"

+echo "   - 'High CPU usage and slow performance'" 
+echo "   - 'File permission errors'"

+echo "The agent now supports:"
+echo "- Dynamic eBPF program compilation and execution"
+echo "- AI-driven selection of appropriate tracepoints and kprobes"  
+echo "- Real-time system event monitoring during diagnosis"
+echo "- Integration with Cilium eBPF library for professional-grade monitoring"
