Types

type ActiveServiceTracker

type ActiveServiceTracker struct {
	sync.Mutex
	// contains filtered or unexported fields
}

ActiveServiceTracker keeps track of which services are seen in the trace spans passed through ProcessSpans. It supports expiry of service names if they are not seen for a certain amount of time.

New creates a new initialized service tracker

func (*ActiveServiceTracker) AddSpans

func (a *ActiveServiceTracker) AddSpans(ctx context.Context, spans []*trace.Span) error

AddSpans accepts a list of trace spans and uses them to update the current list of active services. This is thread-safe.

func (*ActiveServiceTracker) CorrelationDatapoints

func (a *ActiveServiceTracker) CorrelationDatapoints() []*datapoint.Datapoint

CorrelationDatapoints returns a list of host correlation datapoints based on the spans sent through ProcessSpans

func (*ActiveServiceTracker) InternalMetrics

func (a *ActiveServiceTracker) InternalMetrics() []*datapoint.Datapoint

InternalMetrics returns datapoint describing the status of the tracker
