func GenerateTestFloatHistograms ¶ added in v0.43.0

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

func GenerateTestGaugeFloatHistogram ¶ added in v0.43.0

func GenerateTestGaugeFloatHistogram(i int) *histogram.FloatHistogram

func GenerateTestGaugeFloatHistograms ¶ added in v0.43.0

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

func GenerateTestGaugeHistogram ¶ added in v0.43.0

func GenerateTestGaugeHistogram(i int) *histogram.Histogram

func GenerateTestGaugeHistograms ¶ added in v0.43.0

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

func GenerateTestHistogram ¶ added in v0.43.0

func GenerateTestHistogram(i int) *histogram.Histogram

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

func GenerateTestHistograms ¶ added in v0.43.0

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

func GenerateTestHistogramsWithUnknownResetHint ¶ added in v0.50.0

func GenerateTestHistogramsWithUnknownResetHint(n int) []*histogram.Histogram

func SetFloatHistogramCounterReset ¶ added in v0.49.0

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

func SetFloatHistogramNotCounterReset ¶ added in v0.45.0

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

func SetHistogramCounterReset ¶ added in v0.49.0

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

func SetHistogramNotCounterReset ¶ added in v0.45.0

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.
