Functions

func EmitTimestamp

func EmitTimestamp(e *Exporter) error

EmitTimestamp instructs the exporter to send metric's timestamps to collectors.

func Hostname

func Hostname(hostname string) func(*Exporter) error

Hostname is an option that specifies the mtail hostname to use in exported metrics.

func OmitProgLabel

func OmitProgLabel(e *Exporter) error

OmitProgLabel sets the Exporter to not put program names in metric labels.

Types

type Exporter

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

Exporter manages the export of metrics to passive and active collectors.

func New

func New(store *metrics.Store, options ...func(*Exporter) error) (*Exporter, error)

New creates a new Exporter.

func (*Exporter) Collect

func (e *Exporter) Collect(c chan<- prometheus.Metric)

Collect implements the prometheus.Collector interface.

func (*Exporter) Describe

func (e *Exporter) Describe(c chan<- *prometheus.Desc)

Describe implements the prometheus.Collector interface.

func (*Exporter) HandleJSON

func (e *Exporter) HandleJSON(w http.ResponseWriter, r *http.Request)

HandleJSON exports the metrics in JSON format via HTTP.

func (*Exporter) HandleVarz

func (e *Exporter) HandleVarz(w http.ResponseWriter, r *http.Request)

HandleVarz exports the metrics in Varz format via HTTP.

func (*Exporter) PushMetrics

func (e *Exporter) PushMetrics()

PushMetrics sends metrics to each of the configured services.

func (*Exporter) RegisterPushExport

func (e *Exporter) RegisterPushExport(p pushOptions)

RegisterPushExport adds a push export connection to the Exporter. Items in the list must describe a Dial()able connection and will have all the metrics pushed to each pushInterval.

func (*Exporter) SetOption

func (e *Exporter) SetOption(options ...func(*Exporter) error) error

SetOption takes one or more option functions and applies them in order to Exporter.

func (*Exporter) StartMetricPush

func (e *Exporter) StartMetricPush()

StartMetricPush pushes metrics to the configured services each interval.
