Types

type DeleteInput

type DeleteInput struct {
	Key *segment.Key
}

type GetInput

type GetInput struct {
	StartTime time.Time
	EndTime   time.Time
	Key       *segment.Key
	Query     *flameql.Query
}

type GetOutput

type GetOutput struct {
	Tree       *tree.Tree
	Timeline   *segment.Timeline
	SpyName    string
	SampleRate uint32
	Units      string
}

type MetricsExporter

type MetricsExporter interface {
	// Evaluate evaluates metrics export rules against the input key and creates
	// prometheus counters for new time series, if required. Returned observer can
	// be used to evaluate and observe particular samples.
	//
	// If there are no matching rules, the function returns false.
	Evaluate(*PutInput) (SampleObserver, bool)
}

MetricsExporter exports values of particular stack traces sample from profiling data as a Prometheus metrics.

type PutInput

type PutInput struct {
	StartTime       time.Time
	EndTime         time.Time
	Key             *segment.Key
	Val             *tree.Tree
	SpyName         string
	SampleRate      uint32
	Units           string
	AggregationType string
}

type SampleObserver

type SampleObserver interface {
	// Observe adds v to the matched counters if k satisfies node selector.
	// k is a sample stack trace where frames are delimited by semicolon.
	// v is the sample value.
	Observe(k []byte, v int)
}
