This is a Feature Request

What would you like to be added

• The "Resource Management for Pods and Containers" page should be updated:
  a section for Swap alongside CPU and Memory.

• Explain how to view configured limits

• Explain how to view usage via kubectl top pod, kubectl top node and monitoring tools (Prometheus, etc.) querying swap relevant metrics (eg: container_swap_usage_bytes)

• Explain how to interpret swap-related Events and Node conditions

• Explain how to troubleshoot “I configured swap, but it doesn’t swap”

• Explain how to troubleshoot noisy neighbour issues

*Explain swap and disk IO metrics relationships

Why is this needed

Provide clear visibility into swap configuration and usage at both the node and pod levels for different user personas (admins, app owners) and enable effective tuning. Kubernetes NodeSwap feature has implications on workload performance and it's important to improve documentation for clear visibility and troubleshooting.
