Types

type Config

type Config struct {
	MaxConcurrent int           `yaml:"max_concurrent"`
	Timeout       time.Duration `yaml:"timeout"`
	MaxSamples    int           `yaml:"max_samples"`

	// The default evaluation interval for the promql engine.
	// Needs to be configured for subqueries to work as it is the default
	// step if not specified.
	DefaultEvaluationInterval time.Duration `yaml:"default_evaluation_interval" category:"advanced"`

	// LookbackDelta determines the time since the last sample after which a time
	// series is considered stale.
	LookbackDelta time.Duration `yaml:"lookback_delta" category:"advanced"`

	PromQLExperimentalFunctionsEnabled bool `yaml:"promql_experimental_functions_enabled" category:"experimental"`

	MimirQueryEngine streamingpromql.FeatureToggles `yaml:"mimir_query_engine" category:"experimental"`
