Types

type Config

type Config struct {
	// Dataformat can be one of the serializer types listed in NewSerializer.
	DataFormat string

	// Support tags in graphite protocol
	GraphiteTagSupport bool

	// Maximum line length in bytes; influx format only
	InfluxMaxLineBytes int

	// Sort field keys, set to true only when debugging as it less performant
	// than unsorted fields; influx format only
	InfluxSortFields bool

	// Support unsigned integer output; influx format only
	InfluxUintSupport bool

	// Prefix to add to all measurements, only supports Graphite
	Prefix string

	// Template for converting telegraf metrics into Graphite
	// only supports Graphite
	Template string

	// Timestamp units to use for JSON formatted output
	TimestampUnits time.Duration

	// Include HEC routing fields for splunkmetric output
	HecRouting bool

	// Point tags to use as the source name for Wavefront (if none found, host will be used).
	WavefrontSourceOverride []string

	// Use Strict rules to sanitize metric and tag names from invalid characters for Wavefront
	// When enabled forward slash (/) and comma (,) will be accepted
	WavefrontUseStrict bool
}

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 NewCarbon2Serializer() (Serializer, error)

func NewGraphiteSerializer

func NewGraphiteSerializer(prefix, template string, tag_support bool) (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 NewNowSerializer

func NewNowSerializer() (Serializer, error)

func NewSerializer

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

NewSerializer a Serializer interface based on the given config.

func NewSplunkmetricSerializer

func NewSplunkmetricSerializer(splunkmetric_hec_routing 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.
