Types

type MetricsExporter

type MetricsExporter struct {
	// contains filtered or unexported fields
}

MetricsExporter exports profiling metrics via Prometheus. It is safe for concurrent use.

func NewExporter

func NewExporter(rules config.MetricExportRules, reg prometheus.Registerer) (*MetricsExporter, error)

NewExporter validates configuration and creates a new prometheus MetricsExporter.

func (MetricsExporter) Observe

func (e MetricsExporter) Observe(k *segment.Key, t *tree.Tree, multiplier float64)

Observe ingested segment key and tree.

The call evaluates export rules against the key k and creates prometheus counters for new time series, if required. Every export rule has an expression to evaluate a dimension key, and a filter, which allow to retrieve metric value for particular nodes.
