jerome 05eccd5b53 chore: consolidate Syslog Solution code into unified repository structure

- Moved scattered scripts, templates, and documentation into organized directories (applications/, scripts/, assets/).
- Updated .gitignore to strictly exclude secrets, state files, and IDE configs.
- Added comprehensive README.md outlining repository structure and best practices.
- Preserved all existing documentation and technical architecture files.
- Prepared infrastructure/ for AWS Org and Proxmox Terraform management.

Troubleshooting Methodology

Step 1: Gather Information

Error messages and logs
System status and metrics
Recent changes or updates
User reports and symptoms

Step 2: Isolate the Problem

Reproduce the issue
Identify affected components
Check dependencies and connections
Verify configurations

Step 3: Diagnose Root Cause

Check logs and monitoring
Test individual components
Compare with known working state
Identify configuration drift

Step 4: Apply Fix

Implement solution
Test thoroughly
Document the fix
Update monitoring alerts

Step 5: Prevent Recurrence

Update documentation
Add monitoring checks
Create automation scripts
Train team members

Quick Reference

Common Commands

# Check system logs
journalctl -xe --no-pager | tail -100

# Check GPU status
rocm-smi
nvidia-smi

# Check network connectivity
ping -c 4 8.8.8.8
traceroute google.com

# Check disk space
df -h
du -sh /path/to/directory

# Check running processes
top -b -n 1 | head -20
ps aux | grep -i process_name

Log Locations

Proxmox: /var/log/pve/
System: /var/log/syslog, /var/log/messages
GPU: /var/log/kern.log (dmesg)
AWS: CloudWatch Logs
Applications: Application-specific log directories

Emergency Procedures

Critical Issues

Service Down: Check status, restart if needed, investigate root cause
Data Loss: Stop writes, assess backup, restore from backup
Security Breach: Isolate system, preserve logs, investigate scope
Performance Crisis: Throttle traffic, scale resources, optimize
