PANTAW COLLECTOR · STORAGE

smart collector

Collect bounded disk health facts from smartctl JSON.

Source and collected facts

A fixed smartctl -j -a command per validated block-device name through the shared command helper.

device and model
overall SMART pass state
temperature
power-on hours

Observation contract

Usable SMART JSON produces SUCCESS or PARTIAL depending on completeness; missing tools, denied access, timeouts or unusable data produce UNAVAILABLE or PARTIAL with bounded diagnostics.

Relevant ReasonCode values: SMART_OBSERVED, SMART_PARTIAL, INTERNAL_ERROR

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

Graceful unavailability and limits

Requires smartctl. USB bridges, virtual disks and controller passthrough may hide or alter telemetry.

Permissions and privacy

Permissions. Device access often requires an explicit udev rule, capability or narrowly scoped privilege.

Privacy. Disk model and lifetime data can be sensitive; unrestricted smartctl output and serials are not retained in the snapshot.

Sanitized example

{
  "source": "smart",
  "status": "SUCCESS",
  "severity": "INFO",
  "reason_code": "SMART_OBSERVED",
  "target": "device:sda",
  "metadata": {"model_name":"Example SSD","smart_passed":true,"temperature_celsius":35,"power_on_hours":1200}
}
