Functions

func HashRule

func HashRule(r Rule) uint64

HashRule hashes significant Rule fields into unique hash value

Types

type Group

type Group struct {
	File        string
	Name        string        `yaml:"name"`
	Interval    time.Duration `yaml:"interval,omitempty"`
	Rules       []Rule        `yaml:"rules"`
	Concurrency int           `yaml:"concurrency"`

	// 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) Validate

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

Validate check for internal Group or Rule configuration errors

type Rule

type Rule struct {
	ID          uint64
	Record      string            `yaml:"record,omitempty"`
	Alert       string            `yaml:"alert,omitempty"`
	Expr        string            `yaml:"expr"`
	For         time.Duration     `yaml:"for,omitempty"`
	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) 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
