feat(health): report NMX-C health for NVLink domains - #5445
Conversation
Signed-off-by: Jay Zhu <jayzhu@nvidia.com>
Summary by CodeRabbit
WalkthroughAdds an opt-in NVLink domain health-report sink for validated NMX-C controller health events. The change adds configuration validation, domain-state processing, sequential report submission, queue deduplication, API integration, startup wiring, tests, and operational documentation. ChangesNMX-C NVLink health reporting
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR adds NVLink domain health reporting, but its background submission worker can remain alive and retain resources until runtime shutdown because it lacks cancellation and joining. Merge readiness requires lifecycle cleanup or explicit owner acceptance of this bounded shutdown risk. Sequence Diagram(s)sequenceDiagram

| When `[sinks.nvlink_domain_health_report]` is enabled, the hardware health | ||

Enabling this sink alone does not cause the stated submissions: [collectors.nmxc] is disabled by default, and collector_eligibility requires ctx.nmxc_config.is_enabled() before any NMX-C stream starts. An operator following this section can therefore enable the sink and receive no reports without an explanation or error; document that the collector must also be enabled and that an eligible primary switch-host endpoint is required.

Introducing NmxControllerHealth here leaves the linked shared contracts inconsistent: docs/architecture/health_aggregation.md still says the probe field is limited to BmcSensor, IntrusionSensorTriggered, BmcLeakDetection, NvueLeakage, or SkuValidation, and docs/architecture/health/health_probe_ids.md does not list the new public ID. Update those canonical references so consumers do not treat valid domain reports as outside the documented schema.

Add cancellation and task joining for the submission worker.
NvLinkDomainHealthReportSink::new detaches a worker that waits indefinitely on DedupQueue::next(). Store its JoinHandle and a CancellationToken in the sink lifecycle owner. Cancel and await the worker during shutdown so it does not retain the queue and continue until runtime shutdown.
