## 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**
|
|
```bash
|
|
# 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**
|
|
1. **Service Down:** Check status, restart if needed, investigate root cause
|
|
2. **Data Loss:** Stop writes, assess backup, restore from backup
|
|
3. **Security Breach:** Isolate system, preserve logs, investigate scope
|
|
4. **Performance Crisis:** Throttle traffic, scale resources, optimize
|
|
|
|
### **Contact Escalation**
|
|
- **Level 1:** System administrators
|
|
- **Level 2:** Technical lead
|
|
- **Level 3:** External support (vendor, consultant)
|
|
- **Level 4:** Emergency response team
