$avgTime = ($results.DurationMs | Measure-Object -Average).Average
Write-Host "`nAverage Response Time: $([math]::Round($avgTime, 2))ms"
Expected Output: Response times under 5 seconds, high success rate
Step 7.2: Resource Efficiency Check
# Check resource efficiency
$podMetrics = kubectl top pods -n edge-rag
Write-Host "Resource Usage Summary:"
Write-Host "─" * 60
$podMetrics | ForEach-Object {
$cpu = $_.CPU
$mem = $_.MEMORY

Expected Output: Efficient resource utilization
Step 8: Next Steps and Scaling
Objective: Plan for production deployment

Write-Host "Services: $($serviceInfo.Count - 1)"
$pvcInfo = kubectl get pvc -n edge-rag
Write-Host "Storage Allocated: $(($pvcInfo | Measure-Object).Count) PVCs"
Write-Host "`nScaling Recommendations:"
Write-Host "- RAG API: Current 2 replicas, can scale to 5+"
Write-Host "- Weaviate: Requires persistent storage, single instance optimal"
Write-Host "- Ollama: Consider GPU-enabled node for better performance"
Step 8.2: Export Configuration for Lab 4
# Export current RAG setup for reference in Lab 4
kubectl get all -n edge-rag -o yaml > edge-rag-backup.yaml
Write-Host "Configuration exported to edge-rag-backup.yaml"
Write-Host "This will be referenced in Lab 4 for policy governance"

Troubleshooting
| Issue | Solution |
|---|---|
| Ollama model pull timeout | Increase timeout or use smaller model (tinyllama) |
| Weaviate connection errors | Check Pod IP: kubectl get pods -n edge-rag -o wide |
| RAG API pods crashing | Check logs: kubectl logs <pod> -n edge-rag |
| Out of memory errors | Reduce model size or increase Pod limits |
| Embedding generation slow | Consider GPU or batch processing |
| Vector search returning no results | Verify documents were ingested: check Weaviate logs |
