Semantic conventions for network metrics

Status: Development

Network metrics hw.network.*

A physical network interface, or a network interface controller (NIC), excluding software-based virtual adapters and loopbacks. For example, a physical network interface on a server, switch, router or firewall, an HBA, a fiber channel port or a Wi-Fi adapter.

Metric: hw.errors (Network)

This metric is recommended.

Number of errors encountered by the network adapter.

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

• hw.type MUST be set to "network" to indicate that the errors are from a network adapter.

The following attributes SHOULD be set:

• error.type SHOULD be set to indicate the type of error, such as "zero_buffer_credit", "crc", etc.
• hw.network.direction SHOULD be set to indicate the direction of the error, either "receive" or "transmit".

[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.

[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.
