Functions

func New

func New(
	ctx context.Context, cfg *server.Config, st store.Store, registry *prometheus.Registry,
) (server.Server, error)

New constructs a http server to server the metrics

func ReadMetrics

func ReadMetrics(
	ctx context.Context, URL string, tlsConfig *tls.Config,
) (map[string]*dto.MetricFamily, error)

ReadMetrics reads the metrics from the endpoint and returns a map of dto.MetricFamily

func WriteMetrics

func WriteMetrics(
	ctx context.Context,
	metricFamilies map[string]*dto.MetricFamily,
	rewrite bool,
	translators []translator.Translator,
	out io.Writer,
) error

WriteMetrics writes the metrics, converting HDR Histogram into Log10 linear histograms.
