SSFMetrics Sink

This sink extracts metrics from SSF spans and creates SLI metrics from indicator spans.

Configuration

The indicator_span_timer_name controls the generated metric name.

Status

This sink is stable. Some some encoding or options may change, as it is in active development.

Capabilities

SSF spans contain a Metric field which can contain many SSF metrics. This sink adds those metrics to Veneur's aggregators.

Indicators

Additionally, if a SSF span's indicator flag is true, then a timer will be added for Veneur's next flush. The indicator_span_timer_name controls the name used. The following tags are also set:

SSF field name is mapped to the tag span_name
SSF field service is mapped to the tag service
SSF field error is mapped to the tag error with a value of true or false
The unit of the metric is nanoseconds

Types ¶

type DerivedMetricsSink ¶

type DerivedMetricsSink interface {
	sinks.SpanSink
	samplers.DerivedMetricsProcessor
}

DerivedMetricsSink composes the functionality of a SpanSink and DerivedMetricsProcessor

func NewMetricExtractionSink ¶

func NewMetricExtractionSink(mw []Processor, indicatorTimerName, objectiveTimerName string, cl *trace.Client, log *logrus.Logger) (DerivedMetricsSink, error)

NewMetricExtractionSink sets up and creates a span sink that extracts metrics ("samples") from SSF spans and reports them to a veneur's metrics workers.

type Processor ¶

type Processor interface {
	// IngestUDP takes a single UDPMetric and processes it in the worker.
	IngestUDP(samplers.UDPMetric)
}

Processor represents a thing that can process UDPMetrics.
