Functions ¶
func ChunkFromSamples ¶
ChunkFromSamples requires all samples to have the same type.
func ChunkFromSamplesGeneric ¶
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 GenerateTestHistogram ¶
GenerateTestHistogram but it is up to the user to set any known counter reset hint.
func GenerateTestHistograms ¶
func PopulatedChunk ¶
PopulatedChunk creates a chunk populated with samples every second starting at minTime
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.
type Sample ¶
type Sample interface {
T() int64
V() float64
H() *histogram.Histogram
FH() *histogram.FloatHistogram
Type() chunkenc.ValueType
}
func GenerateSamples ¶
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
