Functions

func ChunkFromSamples

func ChunkFromSamples(s []Sample) chunks.Meta

ChunkFromSamples requires all samples to have the same type.

func ChunkFromSamplesGeneric

func ChunkFromSamplesGeneric(s Samples) chunks.Meta

ChunkFromSamplesGeneric requires all samples to have the same type.

func GenerateTestFloatHistogram

func GenerateTestFloatHistogram(i int) *histogram.FloatHistogram

GenerateTestFloatHistogram but it is up to the user to set any known counter reset hint.

func GenerateTestFloatHistograms

func GenerateTestFloatHistograms(n int) (r []*histogram.FloatHistogram)

func GenerateTestGaugeFloatHistogram

func GenerateTestGaugeFloatHistogram(i int) *histogram.FloatHistogram

func GenerateTestGaugeFloatHistograms

func GenerateTestGaugeFloatHistograms(n int) (r []*histogram.FloatHistogram)

func GenerateTestGaugeHistogram

func GenerateTestGaugeHistogram(i int) *histogram.Histogram

func GenerateTestGaugeHistograms

func GenerateTestGaugeHistograms(n int) (r []*histogram.Histogram)

func GenerateTestHistogram

func GenerateTestHistogram(i int) *histogram.Histogram

GenerateTestHistogram but it is up to the user to set any known counter reset hint.

func GenerateTestHistograms

func GenerateTestHistograms(n int) (r []*histogram.Histogram)

func PopulatedChunk

func PopulatedChunk(numSamples int, minTime int64) chunks.Meta

PopulatedChunk creates a chunk populated with samples every second starting at minTime

func SetFloatHistogramNotCounterReset

func SetFloatHistogramNotCounterReset(h *histogram.FloatHistogram) *histogram.FloatHistogram

func SetHistogramNotCounterReset

func SetHistogramNotCounterReset(h *histogram.Histogram) *histogram.Histogram

func TestDirLockerUsage

func TestDirLockerUsage(t *testing.T, open func(t *testing.T, data string, createLock bool) (*DirLocker, testutil.Closer))

TestDirLockerUsage performs a set of tests which guarantee correct usage of DirLocker. open should use data as the storage directory, and createLock to determine if a lock file should be used.

Types

type DirLocker

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

func NewDirLocker

func NewDirLocker(dir, subsystem string, l log.Logger, r prometheus.Registerer) (*DirLocker, error)

NewDirLocker creates a DirLocker that can obtain an exclusive lock on dir.

func (*DirLocker) Lock

func (l *DirLocker) Lock() error

Lock obtains the lock on the locker directory.

func (*DirLocker) Release

func (l *DirLocker) Release() error

Release releases the lock. No-op if the lock is not held.

type Sample

type Sample interface {
	T() int64
	F() float64

}

func GenerateSamples

func GenerateSamples(start, numSamples int) []Sample

GenerateSamples starting at start and counting up numSamples.

type SampleSlice

type SampleSlice []Sample

func (SampleSlice) Get

func (s SampleSlice) Get(i int) Sample

func (SampleSlice) Len

func (s SampleSlice) Len() int

type Samples
