[dmitsh]

Summary by CodeRabbit

• Configuration
  • Updated Kubernetes configuration to recognize Topograph accelerator domain and fabric tier topology labels instead of the former NVIDIA network topology labels.
• Documentation
  • Updated integration documentation and examples to use the current Topograph label keys.
• Tests
  • Updated metadata transformation coverage to reflect the revised topology label names and ensure consistent handling of these labels.

📝 Walkthrough

Walkthrough

The change replaces NVIDIA network topology labels with Topograph accelerator domain and fabric tier labels in Kubernetes configuration, integration documentation, and metadata transformer tests.

Changes

Topograph topology label migration

Layer / File(s)	Summary
Update topology labels and validation distros/kubernetes/nvsentinel/values*.yaml, platform-connectors/pkg/transformers/metadata/transformer_test.go, docs/INTEGRATIONS.md	Allowed labels, transformer test data, validation assertions, documentation, and the CEL example now use Topograph label keys. Test configuration alignment also changed without behavior changes.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 43592

This migration updates topology metadata keys, but the documented semantics and supported Topograph label subset remain unclear. Users may configure unsupported labels or infer incorrect topology meanings, causing expected metadata to be omitted from downstream events.

Inline comments:
In `@distros/kubernetes/nvsentinel/values.yaml`:
- Around line 433-436: Update the AllowedLabels configuration in
distros/kubernetes/nvsentinel/values.yaml lines 433-436 and
distros/kubernetes/nvsentinel/values-full.yaml lines 401-404 to include the
Topograph sub-domain and supported fabric tiers beyond tier 2, then update the
corresponding coverage in
platform-connectors/pkg/transformers/metadata/transformer_test.go lines 261-286.
If NVSentinel intentionally supports only the current subset, document that
contract in both profiles instead and adjust the test to enforce it.

In `@docs/INTEGRATIONS.md`:
- Around line 742-745: Update the label descriptions in the Topograph
integration documentation to use generic semantics: describe
accelerator.topograph.run/domain as accelerator-interconnect locality, describe
fabric.topograph.run/tier-N as progressively higher switch tiers starting
closest to the node with variable depth, and document the optional
accelerator.topograph.run/sub-domain label. Remove fixed NVLink, leaf, spine,
and core role assumptions.
