Functions

func NewTemplate

func NewTemplate(pattern string, defaultTags map[string]string, separator string) (*template, error)

NewTemplate returns a new template ensuring it has a measurement specified.

Types

type Config

type Config struct {
	Separator string
	Templates []string
}

Config represents the configuration for Graphite endpoints.

func (*Config) Validate

func (c *Config) Validate() error

Validate validates the config's templates and tags.

type GraphiteParser

type GraphiteParser struct {
	Separator   string
	Templates   []string
	DefaultTags map[string]string
	// contains filtered or unexported fields
}

Parser encapsulates a Graphite Parser.

func NewGraphiteParser

func NewGraphiteParser(
	separator string,
	templates []string,
	defaultTags map[string]string,
) (*GraphiteParser, error)

func (*GraphiteParser) ApplyTemplate

func (p *GraphiteParser) ApplyTemplate(line string) (string, map[string]string, string, error)

ApplyTemplate extracts the template fields from the given line and returns the measurement name and tags.

func (*GraphiteParser) Parse

func (p *GraphiteParser) Parse(buf []byte) ([]telegraf.Metric, error)

func (*GraphiteParser) ParseLine

func (p *GraphiteParser) ParseLine(line string) (telegraf.Metric, error)

Parse performs Graphite parsing of a single line.

func (*GraphiteParser) SetDefaultTags

func (p *GraphiteParser) SetDefaultTags(tags map[string]string)

type UnsupposedValueError

type UnsupposedValueError struct {
	Field string
	Value float64
}

An UnsupposedValueError is returned when a parsed value is not supposed.

func (*UnsupposedValueError) Error

func (err *UnsupposedValueError) Error() string
