PANTAW COLLECTOR · HARDWARE

dimm_ecc collector

Observe EDAC memory-controller, DIMM inventory and ECC counters where the kernel exposes them.

Source and collected facts

Direct read-only sysfs inspection under /sys/devices/system/edac/mc.

memory controller and DIMM
label and location
size and memory type
EDAC mode
correctable and uncorrectable error counts

Observation contract

Usable EDAC/DIMM facts produce SUCCESS; incomplete inventory produces PARTIAL; absent EDAC exposure produces UNAVAILABLE.

Relevant ReasonCode values: DIMM_ECC_OBSERVED, DIMM_ECC_PARTIAL, INTERNAL_ERROR

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

Graceful unavailability and limits

Requires kernel EDAC support and compatible hardware/firmware. Absence does not prove that physical memory lacks ECC.

Permissions and privacy

Permissions. Read access to EDAC sysfs attributes is required.

Privacy. DIMM labels and locations reveal physical topology; no public example uses a real asset identifier.
