	Format:      formatOtlp,
}

DefaultRemoteWriteConfig holds the default settings for a PushConfig.

Types

type Config

type Config struct {

InstanceConfig configures an individual Traces trace pipeline.

func (*InstanceConfig) OtelConfig

func (c *InstanceConfig) OtelConfig() (*otelcol.Config, error)

type JaegerRemoteSamplingConfig

type JaegerRemoteSamplingConfig map[string]interface{}

JaegerRemoteSamplingMap is a set of Jaeger Remote Sampling extensions. Because receivers may be configured with an unknown set of sensitive information, ReceiverMap will marshal as YAML to the text "<secret>".

func (JaegerRemoteSamplingConfig) MarshalYAML

func (jrsm JaegerRemoteSamplingConfig) MarshalYAML() (interface{}, error)

MarshalYAML implements yaml.Marshaler.

type OAuth2Config

type OAuth2Config struct {

OAuth2Config configures the oauth2client extension for a remote_write exporter compatible with oauth2clientauthextension.Config

type ReceiverMap

type ReceiverMap map[string]interface{}

ReceiverMap stores a set of receivers. Because receivers may be configured with an unknown set of sensitive information, ReceiverMap will marshal as YAML to the text "<secret>".

MarshalYAML implements yaml.Marshaler.

func (*ReceiverMap) UnmarshalYAML

func (r *ReceiverMap) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements yaml.Unmarshaler.

	// * "AGGREGATION_TEMPORALITY_CUMULATIVE"
	// * "AGGREGATION_TEMPORALITY_DELTA"
