nvmlFieldValue_t

struct nvmlFieldValue_t

Information for a Field Value Sample.

Public Members

unsigned int fieldId

ID of the NVML field to retrieve. This must be set before any call that uses this struct. See the constants starting with NVML_FI_ above.

unsigned int scopeId

Scope ID can represent data used by NVML depending on fieldId’s context. For example, for NVLink throughput counter data, scopeId can represent linkId.

long long timestamp

CPU Timestamp of this value in microseconds since 1970.

long long latencyUsec

How long this field value took to update (in usec) within NVML. This may be averaged across several fields that are serviced by the same driver call.

nvmlValueType_t valueType

Type of the value stored in value.

nvmlReturn_t nvmlReturn

Return code for retrieving this value. This must be checked before looking at value, as value is undefined if nvmlReturn != NVML_SUCCESS.

nvmlValue_t value

Value for this field. This is only valid if nvmlReturn == NVML_SUCCESS.
