Functions

func HashRule

func HashRule(r Rule) uint64

HashRule hashes significant Rule fields into unique hash that supposed to define Rule uniqueness

Types

type Group

type Group struct {
	Type        datasource.Type `yaml:"type,omitempty"`
	File        string
	Name        string        `yaml:"name"`
	Interval    time.Duration `yaml:"interval,omitempty"`
	Rules       []Rule        `yaml:"rules"`
	Concurrency int           `yaml:"concurrency"`
	// Checksum stores the hash of yaml definition for this group.
	// May be used to detect any changes like rules re-ordering etc.
	Checksum string

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

Group contains list of Rules grouped into entity with one name and evaluation interval

func Parse

func Parse(pathPatterns []string, validateAnnotations, validateExpressions bool) ([]Group, error)

Parse parses rule configs from given file patterns

func (*Group) UnmarshalYAML

func (g *Group) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

func (*Group) Validate

func (g *Group) Validate(validateAnnotations, validateExpressions bool) error

Validate check for internal Group or Rule configuration errors

type PromDuration

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

PromDuration is Prometheus duration.

func NewPromDuration

func NewPromDuration(d time.Duration) PromDuration

NewPromDuration returns PromDuration for given d.

func (*PromDuration) Duration

func (pd *PromDuration) Duration() time.Duration

Duration returns duration for pd.

func (PromDuration) MarshalYAML

func (pd PromDuration) MarshalYAML() (interface{}, error)

MarshalYAML implements yaml.Marshaler interface.

func (*PromDuration) UnmarshalYAML

func (pd *PromDuration) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements yaml.Unmarshaler interface.

type Rule

type Rule struct {
	ID          uint64
	Type        datasource.Type   `yaml:"type,omitempty"`
	Record      string            `yaml:"record,omitempty"`
	Alert       string            `yaml:"alert,omitempty"`
	Expr        string            `yaml:"expr"`
	For         PromDuration      `yaml:"for"`
	Labels      map[string]string `yaml:"labels,omitempty"`
	Annotations map[string]string `yaml:"annotations,omitempty"`

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

Rule describes entity that represent either recording rule or alerting rule.

func (*Rule) Name

func (r *Rule) Name() string

Name returns Rule name according to its type

func (*Rule) UnmarshalYAML

func (r *Rule) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

func (*Rule) Validate

func (r *Rule) Validate() error

Validate check for Rule configuration errors
