Overview

Package config defines the data models for entities. This file defines the models for configuration format. The defined entities are: Config (the top-level structure), Receivers, Exporters, Processors, Pipelines.

Receivers, Exporters and Processors typically have common configuration settings, however sometimes specific implementations will have extra configuration settings. This requires the configuration data for these entities to be polymorphic.

To satisfy these requirements we declare interfaces Receiver, Exporter, Processor, which define the behavior. We also provide helper structs ReceiverSettings, ExporterSettings, ProcessorSettings, which define the common settings and un-marshaling from config files.

Specific Receivers/Exporters/Processors are expected to at the minimum implement the corresponding interface and if they have additional settings they must also extend the corresponding common settings struct (the easiest approach is to embed the common struct).

Types

type ComponentID added in v0.25.0

type ComponentID struct {
	// contains filtered or unexported fields
}

ComponentID represents the identity for a component. It combines two values: * type - the Type of the component. * name - the name of that component. The component ComponentID (combination type + name) is unique for a given component.Kind.

func NewID added in v0.26.0

func NewID(typeVal Type) ComponentID

NewID returns a new ComponentID with the given Type and empty name.

func NewIDFromString added in v0.27.0

func NewIDFromString(idStr string) (ComponentID, error)

NewIDFromString decodes a string in type[/name] format into ComponentID. The type and name components will have spaces trimmed, the "type" part must be present, the forward slash and "name" are optional. The returned ComponentID will be invalid if err is not-nil.

func NewIDWithName added in v0.26.0

func NewIDWithName(typeVal Type, nameVal string) ComponentID

NewIDWithName returns a new ComponentID with the given Type and name.

func (ComponentID) Name added in v0.25.0

func (id ComponentID) Name() string

Name returns the custom name of the component.

func (ComponentID) String added in v0.25.0

func (id ComponentID) String() string

String returns the ComponentID string representation as "type[/name]" format.

func (ComponentID) Type added in v0.25.0

func (id ComponentID) Type() Type

Type returns the type of the component.

type Config added in v0.24.0

Config defines the configuration for the various elements of collector or agent.

func (*Config) Validate added in v0.24.0

func (cfg *Config) Validate() error

Validate returns an error if the config is invalid.

This function performs basic validation of configuration. There may be more subtle invalid cases that we currently don't check for but which we may want to add in the future (e.g. disallowing receiving and exporting on the same endpoint).

type DataType added in v0.24.0

type DataType string

DataType is the data type that is supported for collection. We currently support collecting metrics, traces and logs, this can expand in the future.

const (
	// TracesDataType is the data type tag for traces.
	TracesDataType DataType = "traces"

	// MetricsDataType is the data type tag for metrics.
	MetricsDataType DataType = "metrics"

	// LogsDataType is the data type tag for logs.
	LogsDataType DataType = "logs"
)

Currently supported data types. Add new data types here when new types are supported in the future.

type Exporter added in v0.24.0

type Exporter interface {
	// contains filtered or unexported methods
}

Exporter is the configuration of a component.Exporter. Specific extensions must implement this interface and must embed ExporterSettings struct or a struct that extends it.

type ExporterSettings added in v0.24.0

type ExporterSettings struct {
	// contains filtered or unexported fields
}

ExporterSettings defines common settings for a component.Exporter configuration. Specific exporters can embed this struct and extend it with more fields if needed.

It is highly recommended to "override" the Validate() function.

When embedded in the exporter config, it must be with `mapstructure:",squash"` tag.

Exporters is a map of names to Exporters.

type Extension added in v0.24.0

type Extension interface {

type ExtensionSettings added in v0.24.0

type ExtensionSettings struct {
	// contains filtered or unexported fields
}

It is highly recommended to "override" the Validate() function.

When embedded in the extension config, it must be with `mapstructure:",squash"` tag.

func NewExtensionSettings added in v0.24.0

func NewExtensionSettings(id ComponentID) ExtensionSettings

NewExtensionSettings return a new ExtensionSettings with the given ComponentID.

ID returns the receiver ComponentID.

func (rs *ExtensionSettings) SetIDName(idName string)

SetIDName sets the receiver name.
