Semantic conventions for tape drive metrics

Status: Development

Tape drive metrics hw.tape_drive.*

A tape drive in a computer or in a tape library (excluding virtual tape libraries).

hw.type MUST be set to "tape_drive".

All tape drive metrics may include the below attributes:

Attribute Type Description Examples Requirement Level Stability
hw.id string An identifier for the hardware component, unique within the monitored host win32battery_battery_testsysa33_1 Required Development
hw.model string Descriptive model name of the hardware component PERC H740P; Intel(R) Core(TM) i7-10700K; Dell XPS 15 Battery Recommended Development
hw.name string An easily-recognizable name for the hardware component eth0 Recommended Development
hw.parent string Unique identifier of the parent component (typically the hw.id attribute of the enclosure, or disk controller) dellStorage_perc_0 Recommended Development
hw.serial_number string Serial number of the hardware component CNFCP0123456789 Recommended Development
hw.vendor string Vendor name of the hardware component Dell; HP; Intel; AMD; LSI; Lenovo Recommended Development

Metric: hw.errors (Tape Drive)

This metric is recommended.

Number of errors encountered by the tape drive.

When using this metric, the following attributes MUST be set:

  • hw.type MUST be set to "tape_drive" to indicate that the errors are from a tape drive.

The following attributes SHOULD be set:

  • error.type SHOULD be set to indicate the type of error, such as "read", "write", "mount", etc.
Name Instrument Type Unit (UCUM) Description Stability Entity Associations
hw.errors Counter {error} Number of errors encountered by the component. Development
Attribute Type Description Examples Requirement Level Stability
hw.id string An identifier for the hardware component, unique within the monitored host win32battery_battery_testsysa33_1 Required Development
hw.type string Type of the component [1] battery; cpu; disk_controller Required Development
error.type string The type of error encountered by the component. [2] uncorrected; zero_buffer_credit; crc; bad_sector Conditionally Required if and only if an error has occurred Stable
hw.name string An easily-recognizable name for the hardware component eth0 Recommended Development
hw.parent string Unique identifier of the parent component (typically the hw.id attribute of the enclosure, or disk controller) dellStorage_perc_0 Recommended Development
network.io.direction string Direction of network traffic for network errors. [3] receive; transmit Recommended Development

[1] hw.type: Describes the category of the hardware component for which hw.state is being reported. For example, hw.type=temperature along with hw.state=degraded would indicate that the temperature of the hardware component has been reported as degraded.

[2] error.type: The error.type SHOULD match the error code reported by the component, the canonical name of the error, or another low-cardinality error identifier. Instrumentations SHOULD document the list of errors they report.

[3] network.io.direction: This attribute SHOULD only be used when hw.type is set to "network" to indicate the direction of the error.

error.type has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

Value Description Stability
_OTHER A fallback error value to be used when the instrumentation doesn't define a custom value. Stable

hw.type has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

network.io.direction has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

Value Description Stability

transmit transmit Development

Metric: hw.tape_drive.operations

This metric is recommended.

Operations performed by the tape drive.

The following attributes SHOULD be set:

  • hw.tape_drive.operation_type SHOULD be set to indicate the type of operation, such as "mount", "unmount", or "clean".
Name Instrument Type Unit (UCUM) Description Stability Entity Associations
hw.tape_drive.operations Counter {operation} Operations performed by the tape drive. Development
Attribute Type Description Examples Requirement Level Stability
hw.id string An identifier for the hardware component, unique within the monitored host win32battery_battery_testsysa33_1 Required Development
hw.model string Descriptive model name of the hardware component PERC H740P; Intel(R) Core(TM) i7-10700K; Dell XPS 15 Battery Recommended Development
hw.name string An easily-recognizable name for the hardware component eth0 Recommended Development
hw.parent string Unique identifier of the parent component (typically the hw.id attribute of the enclosure, or disk controller) dellStorage_perc_0 Recommended Development
hw.serial_number string Serial number of the hardware component CNFCP0123456789 Recommended Development
hw.tape_drive.operation_type string Type of tape drive operation mount; unmount; clean Recommended Development
hw.vendor string Vendor name of the hardware component Dell; HP; Intel; AMD; LSI; Lenovo Recommended Development

hw.tape_drive.operation_type has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.

Value Description Stability
clean Clean Development
mount Mount Development
unmount Unmount Development

Metric: hw.status (Tape Drive)

This metric is recommended.

Operational status: 1 (true) or 0 (false) for each of the possible states.

When using this metric for tape drive status, the following attributes MUST be set:

  • hw.type MUST be set to "tape_drive" to indicate that the status is for a tape drive.
  • hw.state MUST be set to one of the following values to indicate the tape drive state:
    • "ok": The tape drive is operating normally.
    • "degraded": The tape drive is operating with reduced functionality or performance.
    • "failed": The tape drive has failed and is not operational.
    • "needs_cleaning": The tape drive requires cleaning.
Name Instrument Type Unit (UCUM) Description Stability Entity Associations
hw.status UpDownCounter 1 Operational status: 1 (true) or 0 (false) for each of the possible states. [1] Development

[1]: hw.status is currently specified as an UpDownCounter but would ideally be represented using a StateSet as defined in OpenMetrics. This semantic convention will be updated once StateSet is specified in OpenTelemetry. This planned change is not expected to have any consequence on the way users query their timeseries backend to retrieve the values of hw.status over time.

Attribute Type Description Examples Requirement Level Stability
hw.id string An identifier for the hardware component, unique within the monitored host win32battery_battery_testsysa33_1 Required Development
hw.state string The current state of the component degraded; failed; needs_cleaning Required Development
hw.type string Type of the component [1] battery; cpu; disk_controller Required Development
hw.name string An easily-recognizable name for the hardware component eth0 Recommended Development
hw.parent string Unique identifier of the parent component (typically the hw.id attribute of the enclosure, or disk controller) dellStorage_perc_0 Recommended Development

[1] hw.type: Describes the category of the hardware component for which hw.state is being reported. For example, hw.type=temperature along with hw.state=degraded would indicate that the temperature of the hardware component has been reported as degraded.

hw.state has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
