Functions

func New

func New(ctx context.Context, cfg Config) components.Component

Types

type Config

type Config struct {
	Query query_config.Config `json:"query"`
}

func ParseConfig

func ParseConfig(b any, db *sql.DB) (*Config, error)

func (Config) Validate

func (cfg Config) Validate() error

type Output

type Output struct {
	UsagesSMI  []nvidia_query.ParsedSMIPowerReading `json:"usages_smi"`
	UsagesNVML []nvidia_query_nvml.Power            `json:"usages_nvml"`
}

func ParseOutputJSON

func ParseOutputJSON(data []byte) (*Output, error)

func ParseStatePowerUsage

func ParseStatePowerUsage(m map[string]string) (*Output, error)

func ParseStatesToOutput

func ParseStatesToOutput(states ...components.State) (*Output, error)

func ToOutput

func ToOutput(i *nvidia_query.Output) *Output

ToOutput converts nvidia_query.Output to Output. It returns an empty non-nil object, if the input or the required field is nil (e.g., i.SMI).

func (*Output) Evaluate

func (o *Output) Evaluate() (string, bool, error)

Returns the output evaluation reason and its healthy-ness.

func (*Output) JSON

func (o *Output) JSON() ([]byte, error)

func (*Output) States

func (o *Output) States() ([]components.State, error)
