type InstantProfileMeta

type InstantProfileMeta struct {
	PeriodType ValueType
	SampleType ValueType
	Timestamp  int64
	Duration   int64
	Period     int64
}

func MetaFromPprof

func MetaFromPprof(p *profile.Profile, sampleIndex int) InstantProfileMeta

type Profile

type Profile struct {
	Meta        InstantProfileMeta
	FlatSamples map[string]*Sample
}

func CopyInstantProfile

func CopyInstantProfile(p InstantProfile) *Profile

func FromPprof

func FromPprof(ctx context.Context, logger log.Logger, metaStore metastore.ProfileMetaStore, p *profile.Profile, sampleIndex int, normalized bool) (*Profile, error)

func ProfilesFromPprof

func ProfilesFromPprof(ctx context.Context, l log.Logger, s metastore.ProfileMetaStore, p *profile.Profile, normalized bool) ([]*Profile, error)

ProfilesFromPprof extracts a Profile from each sample index included in the pprof profile.

func (*Profile) ProfileMeta

func (fp *Profile) ProfileMeta() InstantProfileMeta

func (*Profile) Samples

	DiffValue int64
	Label     map[string][]string
	NumLabel  map[string][]int64
	NumUnit   map[string][]string
}

func MakeSample

func MakeSample(value int64, locationIds []uuid.UUID) *Sample

MakeSample creates a sample from a stack trace (list of locations) and a value. Mostly meant for testing.

type ScaledInstantProfile

	// contains filtered or unexported fields
}

func (*ScaledInstantProfile) ProfileMeta

func (p *ScaledInstantProfile) ProfileMeta() InstantProfileMeta

func (*ScaledInstantProfile) Samples

func (p *ScaledInstantProfile) Samples() map[string]*Sample

type StacktraceKey

type StacktraceKey []byte

func MakeStacktraceKey

func MakeStacktraceKey(sample *Sample) StacktraceKey

MakeStacktraceKey generates stacktraceKey to be used as a key for maps.

type ValueType

type ValueType struct {
	Type string
	Unit string
}
