Types

type AggregatorConfig 

type AggregatorConfig struct {
	Name         string
	DropOriginal bool
	Period       time.Duration
	Delay        time.Duration

	NameOverride      string

}

AggregatorConfig is the common config for all aggregators.

type Buffer 

type Buffer struct {
	sync.Mutex

	MetricsAdded   selfstat.Stat
	MetricsWritten selfstat.Stat
	MetricsDropped selfstat.Stat
	BufferSize     selfstat.Stat
	BufferLimit    selfstat.Stat
	// contains filtered or unexported fields
}

Buffer stores metrics in a circular buffer.

func NewBuffer 

func NewBuffer(name string, capacity int) *Buffer

NewBuffer returns a new empty Buffer with the given capacity.

func (*Buffer) Accept 

func (b *Buffer) Accept(batch []telegraf.Metric)

Accept marks the batch, acquired from Batch(), as successfully written.

func (*Buffer) Add 

func (b *Buffer) Add(metrics ...telegraf.Metric)

Add adds metrics to the buffer

func (*Buffer) Batch 

func (b *Buffer) Batch(batchSize int) []telegraf.Metric

Batch returns a slice containing up to batchSize of the most recently added metrics. Metrics are ordered from newest to oldest in the batch. The batch must not be modified by the client.

func (*Buffer) Len 

func (b *Buffer) Len() int

Len returns the number of metrics currently in the buffer.

func (*Buffer) Reject 

func (b *Buffer) Reject(batch []telegraf.Metric)

Reject returns the batch, acquired from Batch(), to the buffer and marks it as unsent.

type Filter struct {
	NameDrop []string

	NamePass []string

	FieldDrop []string

	FieldPass []string

	TagDrop []TagFilter
	TagPass []TagFilter

	TagExclude []string

	TagInclude []string
	// contains filtered or unexported fields
}

Filter containing drop/pass and tagdrop/tagpass rules

func (*Filter) IsActive 

func (f *Filter) IsActive() bool

IsActive checking if filter is active

func (*Filter) Modify 

func (f *Filter) Modify(metric telegraf.Metric)

Modify removes any tags and fields from the metric according to the fieldpass/fielddrop and taginclude/tagexclude filters.

func (*Filter) Select 

func (f *Filter) Select(metric telegraf.Metric) bool

Select returns true if the metric matches according to the namepass/namedrop and tagpass/tagdrop filters. The metric is not modified.

type InputConfig
