func InitializeMetricSlice

func InitializeMetricSlice(metricData data.MetricData) pdata.MetricSlice

Initializes a metric with a metric slice and returns it.

type Config

type Config interface {
}

Config is the configuration of a scraper.

type ConfigSettings

type ConfigSettings struct {
}

ConfigSettings provides common settings for scraper configuration.

type Factory

type Factory interface {
	// CreateDefaultConfig creates the default configuration for the Scraper.
	CreateDefaultConfig() Config

	// CreateMetricsScraper creates a scraper based on this config.
	// If the config is not valid, error will be returned instead.
	CreateMetricsScraper(
		ctx context.Context,
		logger *zap.Logger,
		cfg Config) (Scraper, error)
}

Factory can create a Scraper.

type Scraper

type Scraper interface {
	// Initialize performs any timely initialization tasks such as
	// setting up performance counters for initial collection.
	Initialize(ctx context.Context) error
	// Close should clean up any unmanaged resources such as
	// performance counter handles.
	Close(ctx context.Context) error
	// ScrapeMetrics returns relevant scraped metrics. If errors occur
	// scraping some metrics, an error should be returned, but any
	// metrics that were successfully scraped should still be returned.
	ScrapeMetrics(ctx context.Context) (pdata.MetricSlice, error)
}

Scraper gathers metrics from the host machine and converts these into internal metrics format.
