Count of hours in power-on state. The raw value of this attribute

shows total count of hours (or minutes, or seconds, depending on manufacturer)

in power-on state. "By default, the total expected lifetime of a hard disk

in perfect condition is defined as 5 years (running every day and night on

all days). This is equal to 1825 days in 24/7 mode or 43800 hours." On some

pre-2005 drives, this raw value may advance erratically and/or "wrap around"

(reset to zero periodically). https://en.wikipedia.org/wiki/S.M.A.R.T.#Known_ATA_S.M.A.R.T._attributes

Contains a vendor specific estimate of the percentage of NVM subsystem

life used based on the actual usage and the manufacturer's prediction of NVM

life. A value of 100 indicates that the estimated endurance of the NVM in

the NVM subsystem has been consumed, but may not indicate an NVM subsystem

failure. The value is allowed to exceed 100. Percentages greater than 254

shall be represented as 255. This value shall be updated once per power-on

hour (when the controller is not in a sleep state).

The exit statuses of smartctl are defined by a bitmask but in decimal value. The eight different bits in the exit status have the following meanings for ATA disks; some of these values may also be returned for SCSI disks.

Bit 0: Command line did not parse.

Bit 1: Device open failed, device did not return an IDENTIFY DEVICE structure, or device is in a low-power mode (see '-n' option above).

Bit 2: Some SMART or other ATA command to the disk failed, or there was a checksum error in a SMART data structure (see '-b' option above).

Bit 3: SMART status check returned "DISK FAILING".

Bit 4: We found prefail Attributes <= threshold.

Bit 5: SMART status check returned "DISK OK" but we found that some (usage or prefail) Attributes have been <= threshold at some time in the past.

Bit 6: The device error log contains records of errors.

Bit 7: The device self-test log contains records of errors. [ATA only] Failed self-tests outdated by a newer successful extended self-test are ignored.

Preprocessing

• JSON Path: $.exit_status

• Discard unchanged with heartbeat: 6h

Stores data related to the rate of hardware read errors that occurred when reading data from a disk surface. The raw value has different structure for different vendors and is often not meaningful as a decimal number. For some drives, this number may increase during normal operation without necessarily signifying errors.

Average time of spindle spin up (from zero RPM to fully operational [milliseconds]).

Preprocessing

• JSON Path: $.spin_up_time.value

• Discard unchanged with heartbeat: 6h

A tally of spindle start/stop cycles. The spindle turns on, and hence the count is increased, both when the hard disk is turned on after having before been turned entirely off (disconnected from power source) and when the hard disk returns from having previously been put to sleep mode.

Preprocessing

• JSON Path: $.reported_uncorrect.value

• Discard unchanged with heartbeat: 6h

Rate of seek errors of the magnetic heads. If there is a partial failure in the mechanical positioning system, then seek errors will arise. Such a failure may be due to numerous factors, such as damage to a servo, or thermal widening of the hard disk. The raw value has different structure for different vendors and is often not meaningful as a decimal number. For some drives, this number may increase during normal operation without necessarily signifying errors.

Command line did not parse.

Device open failed, device did not return an IDENTIFY DEVICE structure, or device is in a low-power mode.

Some SMART or other ATA command to the disk failed,
or there was a checksum error in a SMART data structure.

SMART status check returned "DISK FAILING".

We found prefail Attributes <= threshold.

SMART status check returned "DISK OK" but we found that some (usage
