LightStep Sink
This sink sends Veneur spans to LightStep.
Configuration
See the various lightstep_* keys in example.yaml for all available configuration options.
Status
This sink is stable.
Capabilities
Spans
Enabled if lightstep_access_token is set to non-empty value.
The following rules manage how SSF spans and tags are mapped to LightStep spans:
- The SSF
indicatorfield is converted a tag. - The SSF
servicefield is mapped to LightStep'scomponentfield.
Collector Distribution
Veneur can create lightstep_num_clients number of connections to LightStep
collectors. Veneur will then distribute spans to each of these connections. This
is useful if you don't have a appropriate load-balancer for balancing gRPC
connections. You can also set the lightstep_reconnect_period to change how
often each of these connections reconnect. Using these together can help facilitate
an even distribution of spans across collectors.

Types ¶
type LightStepSpanSink ¶
type LightStepSpanSink struct {
// contains filtered or unexported fields
}
LightStepSpanSink is a sink for spans to be sent to the LightStep client.
func NewLightStepSpanSink ¶
func NewLightStepSpanSink(collector string, reconnectPeriod string, maximumSpans int, numClients int, accessToken string, log *logrus.Logger) (*LightStepSpanSink, error)
NewLightStepSpanSink creates a new instance of a LightStepSpanSink.
func (*LightStepSpanSink) Flush ¶
func (ls *LightStepSpanSink) Flush()
Flush doesn't need to do anything to the LS tracer, so we emit metrics instead.
func (*LightStepSpanSink) Ingest ¶
func (ls *LightStepSpanSink) Ingest(ssfSpan *ssf.SSFSpan) error
Ingest takes in a span and passed it along to the LS client after some sanity checks and improvements are made.
func (*LightStepSpanSink) Name ¶
func (ls *LightStepSpanSink) Name() string
Name returns this sink's name.
