Types

type Configuration added in v0.4.8 

type Configuration struct {
	// RemoteAggregator specifies that downsampling should be done remotely
	// by sending values to a remote m3aggregator cluster which then
	// can forward the aggregated values to stateless m3coordinator backends.
	RemoteAggregator *RemoteAggregatorConfiguration `yaml:"remoteAggregator"`

	// AggregationTypes configs the aggregation types.
	AggregationTypes *aggregation.TypesConfiguration `yaml:"aggregationTypes"`

	// Pool of counter elements.
