type Config

type Config struct {
	configmodels.ProcessorSettings `mapstructure:",squash"`
	// SamplingPercentage is the percentage rate at which traces are going to be sampled. Defaults to zero, i.e.: no sample.
	// Values greater or equal 100 are treated as "sample all traces".
	SamplingPercentage float32 `mapstructure:"sampling_percentage"`
	// HashSeed allows one to configure the hashing seed. This is important in scenarios where multiple layers of collectors
	// have different sampling rates: if they use the same seed all passing one layer may pass the other even if they have
	// different sampling rates, configuring different seeds avoids that.
	HashSeed uint32 `mapstructure:"hash_seed"`
}

Config has the configuration guiding the trace sampler processor.

type Factory

type Factory struct {
}

Factory is the factory for trace-sample processor.

func (*Factory) CreateDefaultConfig

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

CreateDefaultConfig creates the default configuration for processor.

func (*Factory) CreateMetricsProcessor

func (f *Factory) CreateMetricsProcessor(
	logger *zap.Logger,
	nextConsumer consumer.MetricsConsumerOld,
	cfg configmodels.Processor,
) (component.MetricsProcessorOld, error)

CreateMetricsProcessor creates a metrics processor based on this config.

func (*Factory) CreateTraceProcessor

func (f *Factory) CreateTraceProcessor(
	logger *zap.Logger,
	nextConsumer consumer.TraceConsumerOld,
	cfg configmodels.Processor,
) (component.TraceProcessorOld, error)

CreateTraceProcessor creates a trace processor based on this config.

func (*Factory) Type

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

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