Table 1. disk-statistics properties
Name	Type	Description
durable-id	string	Disk ID in the format disk_`enclosure-number.disk-number`.
location	string	The disk location in the format disk_`enclosure-number.disk-number`.
serial-number	string	Disk serial number.
power-on-hours	uint32	The total number of hours that the disk has been powered on since it was manufactured. This value is stored in disk metadata and is updated in 30- minute increments.
bytes-per-second	string	The data transfer rate, in bytes per second, calculated over the interval since these statistics were last requested or reset. This value will be zero if it has not been requested or reset since a controller restart.
bytes-per-second-numeric	uint64	Unformatted bytes-per-second value.
iops	uint32	Input/output operations per second, calculated over the interval since these statistics were last requested or reset. This value will be zero if it has not been requested or reset since a controller restart.
number-of-reads	uint64	Number of read operations since these statistics were last reset or since the controller was restarted.
number-of-writes	uint64	Number of write operations since these statistics were last reset or since the controller was restarted.
data-read	string	Amount of data read since these statistics were last reset or since the controller was restarted.
data-read-numeric	uint64	Unformatted data-read value.
data-written	string	Amount of data written since these statistics were last reset or since the controller was restarted.
data-written-numeric	uint64	Unformatted data-written value.
queue-depth	uint32	Number of pending I/O operations currently being serviced.
lifetime-data-read	string	The amount of data read from the disk in its lifetime.
lifetime-data-read-numeric	uint64	Unformatted lifetime-data-read value.
lifetime-data-written	string	The amount of data written to the disk in its lifetime.
lifetime-data-written-numeric	uint64	Unformatted lifetime-data-written value.
reset-time	string	Date and time, in the format `year-month-day hour:minutes:seconds`, when these statistics were last reset, either by a user or by a controller restart.
reset-time-numeric	uint32	Unformatted reset-time value.
start-sample-time	string	Date and time, in the format `year-month-day hour:minutes:seconds`, when sampling started for the iops and bytes-per-second values.
start-sample-time-numeric	uint32	Unformatted start-sample-time value.
stop-sample-time	string	Date and time, in the format `year-month-day hour:minutes:seconds`, when sampling stopped for the iops and bytes-per-second values.
stop-sample-time-numeric	uint32	Unformatted stop-sample-time value.
smart-count-1	uint32	For port 1, the number of SMART events recorded.
io-timeout-count-1	uint32	For port 1, the number of timeouts accessing the disk.
no-response-count-1	uint32	For port 1, the number of times the disk did not respond.
spinup-retry-count-1	uint32	For port 1, the number of attempts by the storage system to spin up the disk.
number-of-media-errors-1	uint32	For port 1, the number of media errors generated by the disk, as specified by its manufacturer.
number-of-nonmedia-errors-1	uint32	For port 1, the number of other errors generated by the storage system, or generated by the disk and not categorized as media errors.
number-of-block-reassigns-1	uint32	For port 1, the number of times blocks were reassigned to alternate locations.
number-of-bad-blocks-1	uint32	For port 1, the number of bad blocks encountered.
smart-count-2	uint32	For port 2, the number of pending I/O operations currently being serviced.
io-timeout-count-2	uint32	For port 2, the number of SMART events recorded.
no-response-count-2	uint32	For port 2, the number of timeouts accessing the disk.
spinup-retry-count-2	uint32	For port 2, the number of times the disk did not respond.
number-of-media-errors-2	uint32	For port 2, the number of attempts by the storage system to spin up the disk.
