# System Health Monitoring

## Basic Monitoring

Check system health with:

```bash
# Node resource usage
kubectl top nodes

# Pod resource usage
kubectl top pods -A

# Persistent volume claims
kubectl get pvc -A
```

## Advanced Monitoring (Future Implementation)

Consider implementing:

1. **Prometheus + Grafana** for comprehensive monitoring:
   ```bash
   # Placeholder for future implementation
   helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
   helm install prometheus prometheus-community/kube-prometheus-stack --namespace monitoring --create-namespace
   ```

2. **Loki** for log aggregation:
   ```bash
   # Placeholder for future implementation
   helm repo add grafana https://grafana.github.io/helm-charts
   helm install loki grafana/loki-stack --namespace logging --create-namespace
   ```
