Types ¶
type Fanout ¶
type Fanout struct {
// contains filtered or unexported fields
}
Fanout supports the default Alloy style of appendables since it can go to multiple outputs. It also allows the intercepting of appends. It also maintains the responsibility of assigning global ref IDs to a series via the label store.
func NewFanout ¶
func NewFanout(children []storage.Appendable, componentID string, register prometheus.Registerer, ls labelstore.LabelStore) *Fanout
NewFanout creates a fanout appendable.
func (*Fanout) UpdateChildren ¶
func (f *Fanout) UpdateChildren(children []storage.Appendable)
UpdateChildren allows changing of the children of the fanout.
type Interceptor ¶
type Interceptor struct {
// contains filtered or unexported fields
}
Interceptor is a storage.Appendable which invokes callback functions upon getting data. Interceptor should not be modified once created. All callback fields are optional.
func NewInterceptor ¶
func NewInterceptor(next storage.Appendable, opts ...InterceptorOption) *Interceptor
NewInterceptor creates a new Interceptor storage.Appendable. Options can be provided to NewInterceptor to install custom hooks for different methods.
func (*Interceptor) Appender ¶
func (i *Interceptor) Appender(ctx context.Context) storage.Appender
Appender satisfies the Appendable interface.
func (*Interceptor) String ¶ added in v1.12.0
func (i *Interceptor) String() string
type InterceptorOption ¶
type InterceptorOption func(*Interceptor)
InterceptorOption is an option argument passed to NewInterceptor.
func WithAppendHook ¶
func WithAppendHook(f func(ref storage.SeriesRef, l labels.Labels, t int64, v float64, next storage.Appender) (storage.SeriesRef, error)) InterceptorOption
WithAppendHook returns an InterceptorOption which hooks into calls to Append.
func WithCTZeroSampleHook ¶ added in v1.2.0
func WithCTZeroSampleHook(f func(ref storage.SeriesRef, l labels.Labels, t, ct int64, next storage.Appender) (storage.SeriesRef, error)) InterceptorOption
WithCTZeroSampleHook returns an InterceptorOption which hooks into calls to AppendCTZeroSample.
func WithComponentID ¶ added in v1.12.0
func WithComponentID(id string) InterceptorOption
WithComponentID returns an InterceptorOptions which is used to set the componentID of the Interceptor. This is useful for debugging
func WithExemplarHook ¶
func WithExemplarHook(f func(ref storage.SeriesRef, l labels.Labels, e exemplar.Exemplar, next storage.Appender) (storage.SeriesRef, error)) InterceptorOption
WithExemplarHook returns an InterceptorOption which hooks into calls to AppendExemplar.
func WithHistogramHook ¶
func WithHistogramHook(f func(ref storage.SeriesRef, l labels.Labels, t int64, h *histogram.Histogram, fh *histogram.FloatHistogram, next storage.Appender) (storage.SeriesRef, error)) InterceptorOption
WithHistogramHook returns an InterceptorOption which hooks into calls to AppendHistogram.
type NoopMetadataStore ¶
type NoopMetadataStore map[string]scrape.MetricMetadata
NoopMetadataStore implements the MetricMetadataStore interface.
func (NoopMetadataStore) GetMetadata ¶
func (ms NoopMetadataStore) GetMetadata(_ string) (scrape.MetricMetadata, bool)
func (NoopMetadataStore) LengthMetadata ¶
func (ms NoopMetadataStore) LengthMetadata() int
func (NoopMetadataStore) ListMetadata ¶
func (ms NoopMetadataStore) ListMetadata() []scrape.MetricMetadata
func (NoopMetadataStore) SizeMetadata ¶
func (ms NoopMetadataStore) SizeMetadata() int
func (NoopMetadataStore) UpdateMetadata ¶ added in v1.11.0
func (ms NoopMetadataStore) UpdateMetadata(familyName string, md metadata.Metadata)
