Types

type Config

type Config struct {
	Write                WriteConfig `yaml:"write,omitempty" json:"write,omitempty"`
	Read                 ReadConfig  `yaml:"read,omitempty" json:"read,omitempty"`
	DefaultPrefix        string      `yaml:"default_prefix,omitempty" json:"default_prefix,omitempty"`
	EnableTags           bool        `yaml:"enable_tags,omitempty" json:"enable_tags,omitempty"`
	UseOpenMetricsFormat bool        `yaml:"openmetrics,omitempty" json:"openmetrics,omitempty"`

	// Catches all undefined fields and must be empty after parsing.
	XXX map[string]interface{} `yaml:",inline" json:"-"`
}

Config is the graphite configuration.

func (*Config) StoragePrefixFromRequest

func (c *Config) StoragePrefixFromRequest(r *http.Request) string

StoragePrefixFromRequest returns the prefix from either the config or the request's Query

func (Config) String

func (c Config) String() string

func (*Config) UnmarshalYAML

func (c *Config) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

type LabelSet

type LabelSet map[model.LabelName]model.LabelValue

LabelSet pairs a LabelName to a LabelValue.

type LabelSetRE

type LabelSetRE map[model.LabelName]Regexp

LabelSetRE defines pairs like LabelSet but does regular expression

type ReadConfig

type ReadConfig struct {
	URL string `yaml:"url,omitempty" json:"url,omitempty"`
	// If set, MaxPointDelta is used to linearly interpolate intermediate points.
	// It helps support prom1.x reading metrics with larger retention than staleness delta.
	MaxPointDelta time.Duration `yaml:"max_point_delta,omitempty" json:"max_point_delta,omitempty"`

	// Catches all undefined fields and must be empty after parsing.
	XXX map[string]interface{} `yaml:",inline" json:"-"`
}

ReadConfig is the read graphite configuration.

func (*ReadConfig) UnmarshalYAML

func (c *ReadConfig) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

type Regexp

type Regexp struct {
	*regexp.Regexp
}

Regexp encapsulates a regexp.Regexp and makes it YAML marshalable.

func (Regexp) MarshalJSON

func (re Regexp) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaler interface.

func (Regexp) MarshalYAML

func (re Regexp) MarshalYAML() (interface{}, error)

MarshalYAML implements the yaml.Marshaler interface.

func (*Regexp) UnmarshalYAML

func (re *Regexp) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

type Rule

type Rule struct {
	Tmpl     Template   `yaml:"template,omitempty" json:"template,omitempty"`

	// Catches all undefined fields and must be empty after parsing.
	XXX map[string]interface{} `yaml:",inline" json:"-"`
}

Rule defines a templating rule that customize graphite path using the Tmpl if a metric matching the labels exists.

func (*Rule) UnmarshalYAML
