PANTAW COLLECTOR · STORAGE

nvme collector

Inventory NVMe controllers exposed by the Linux kernel.

Source and collected facts

Direct read-only sysfs inspection under /sys/class/nvme; nvme-cli is not required by this collector.

controller name
model and firmware revision
controller state
transport and address

Observation contract

Complete controller inventory produces SUCCESS; missing optional identity or transport fields produce PARTIAL; absent or inaccessible sysfs produces UNAVAILABLE.

Relevant ReasonCode values: NVME_OBSERVED, NVME_PARTIAL, INTERNAL_ERROR

All collectors use structured ObservationStatus values and retain unavailable optional fields explicitly.

Graceful unavailability and limits

This release inventories controllers but does not claim full NVMe health-log telemetry.

Permissions and privacy

Permissions. Read access to NVMe sysfs attributes is required.

Privacy. Controller model, firmware and address can fingerprint hardware topology.
