Overview

Package spanprocessor contains logic to modify top level settings of a span, such as its name.

Index

type Config

type Config struct {
	configmodels.ProcessorSettings `mapstructure:",squash"`

	filterspan.MatchConfig `mapstructure:",squash"`

	// Rename specifies the components required to re-name a span.
	// The `from_attributes` field needs to be set for this processor to be properly
	// configured.
	// Note: The field name is `Rename` to avoid collision with the Name() method
	// from configmodels.ProcessorSettings.NamedEntity
	Rename Name `mapstructure:"name"`
}

Config is the configuration for the span processor. Prior to any actions being applied, each span is compared against the include properties and then the exclude properties if they are specified. This determines if a span is to be processed or not.

type Factory

type Factory struct {
}

Factory is the factory for the Span processor.

func (*Factory) CreateDefaultConfig

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

CreateDefaultConfig creates the default configuration for processor.

func (*Factory) CreateMetricsProcessor

func (f *Factory) CreateMetricsProcessor(
	_ context.Context,
	_ component.ProcessorCreateParams,
	_ consumer.MetricsConsumer,
	_ configmodels.Processor) (component.MetricsProcessor, error)

CreateMetricsProcessor creates a metric processor based on this config.

func (*Factory) CreateTraceProcessor

func (f *Factory) CreateTraceProcessor(
	_ context.Context,
	_ component.ProcessorCreateParams,
	nextConsumer consumer.TraceConsumer,
	cfg configmodels.Processor) (component.TraceProcessor, 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.

type Name

type Name struct {

	// FromAttributes represents the attribute keys to pull the values from to
	// generate the new span name. All attribute keys are required in the span
	// to re-name a span. If any attribute is missing from the span, no re-name
	// will occur.
	// Note: The new span name is constructed in order of the `from_attributes`
	// specified in the configuration. This field is required and cannot be empty.
	FromAttributes []string `mapstructure:"from_attributes"`

	// Separator is the string used to separate attributes values in the new
	// span name. If no value is set, no separator is used between attribute
	// values. Used with FromAttributes only.
	Separator string `mapstructure:"separator"`

	// ToAttributes specifies a configuration to extract attributes from span name.
	ToAttributes *ToAttributes `mapstructure:"to_attributes"`
}

Name specifies the attributes to use to re-name a span.

type ToAttributes

type ToAttributes struct {
	// Rules is a list of rules to extract attribute values from span name. The values
	// in the span name are replaced by extracted attribute names. Each rule in the list
	// is a regex pattern string. Span name is checked against the regex. If it matches
	// then all named subexpressions of the regex are extracted as attributes
	// and are added to the span. Each subexpression name becomes an attribute name and
	// subexpression matched portion becomes the attribute value. The matched portion
	// in the span name is replaced by extracted attribute name. If the attributes
	// already exist in the span then they will be overwritten. The process is repeated
	// for all rules in the order they are specified. Each subsequent rule works on the
	// span name that is the output after processing the previous rule.
	Rules []string `mapstructure:"rules"`

	// BreakAfterMatch specifies if processing of rules should stop after the first
	// match. If it is false rule processing will continue to be performed over the
	// modified span name.
	BreakAfterMatch bool `mapstructure:"break_after_match"`
}
