Types

type Config

}

Config is a struct that covers the data types needed for all serializer types, and can be used to instantiate _any_ of the serializers.

type Serializer

type Serializer interface {
	// Serialize takes a single telegraf metric and turns it into a byte buffer.
	// separate metrics should be separated by a newline, and there should be
	// a newline at the end of the buffer.
	//
	// New plugins should use SerializeBatch instead to allow for non-line
	// delimited metrics.
	Serialize(metric telegraf.Metric) ([]byte, error)

	// SerializeBatch takes an array of telegraf metric and serializes it into
	// a byte buffer.  This method is not required to be suitable for use with
	// line oriented framing.
	SerializeBatch(metrics []telegraf.Metric) ([]byte, error)
}

Serializer is an interface defining functions that a serializer plugin must satisfy.

Implementations of this interface should be reentrant but are not required to be thread-safe.

func NewCarbon2Serializer

func NewGraphiteSerializer

func NewGraphiteSerializer(prefix, template string, tagSupport bool, separator string, templates []string) (Serializer, error)

func NewInfluxSerializer

func NewInfluxSerializer() (Serializer, error)

func NewInfluxSerializerConfig

func NewInfluxSerializerConfig(config *Config) (Serializer, error)

func NewJSONSerializer

func NewJSONSerializer(timestampUnits time.Duration) (Serializer, error)

func NewMsgpackSerializer

func NewMsgpackSerializer() (Serializer, error)

func NewNowSerializer

func NewPrometheusRemoteWriteSerializer

func NewPrometheusRemoteWriteSerializer(config *Config) (Serializer, error)

func NewPrometheusSerializer

func NewPrometheusSerializer(config *Config) (Serializer, error)

func NewSerializer

func NewSerializer(config *Config) (Serializer, error)

NewSerializer a Serializer interface based on the given config.

func NewSplunkmetricSerializer

func NewSplunkmetricSerializer(splunkmetricHecRouting bool, splunkmetricMultimetric bool) (Serializer, error)

func NewWavefrontSerializer

func NewWavefrontSerializer(prefix string, useStrict bool, sourceOverride []string) (Serializer, error)

type SerializerOutput

type SerializerOutput interface {
	// SetSerializer sets the serializer function for the interface.
	SetSerializer(serializer Serializer)
}

SerializerOutput is an interface for output plugins that are able to serialize telegraf metrics into arbitrary data formats.
