Prometheus Exporter

Exports metric data to a Prometheus back-end.

The following settings are required:

• endpoint (no default): Where to send metric data

The following settings can be optionally configured:

• constlabels (no default): key/values that are applied for every exported metric.
• namespace (no default): if set, exports metrics under the provided value.

Example:

exporters:
  prometheus:
    endpoint: "1.2.3.4:1234"
    namespace: test-space
    const_labels:
      label1: value1
      "another label": spaced value

The full list of settings exposed for this exporter are documented here with detailed sample configurations here.

type Config

type Config struct {
	configmodels.ExporterSettings `mapstructure:",squash"` // squash ensures fields are correctly decoded in embedded struct.

	// The address on which the Prometheus scrape handler will be run on.
	Endpoint string `mapstructure:"endpoint"`

	// Namespace if set, exports metrics under the provided value.
	Namespace string `mapstructure:"namespace"`

	// ConstLabels are values that are applied for every exported metric.
	ConstLabels prometheus_golang.Labels `mapstructure:"const_labels"`
}

Config defines configuration for Prometheus exporter.

type Factory

type Factory struct {
}

Factory is the factory for Prometheus exporter.

func (*Factory) CreateDefaultConfig

func (f *Factory) CreateDefaultConfig() configmodels.Exporter

CreateDefaultConfig creates the default configuration for exporter.

func (*Factory) CreateMetricsExporter

func (f *Factory) CreateMetricsExporter(logger *zap.Logger, cfg configmodels.Exporter) (component.MetricsExporterOld, error)

CreateMetricsExporter creates a metrics exporter based on this config.

func (*Factory) CreateTraceExporter

func (f *Factory) CreateTraceExporter(logger *zap.Logger, config configmodels.Exporter) (component.TraceExporterOld, error)

CreateTraceExporter creates a trace exporter based on this config.

func (*Factory) Type

func (f *Factory) Type() configmodels.Type

Type gets the type of the Exporter config created by this factory.
