Interface EvaluatorConfig

public interface EvaluatorConfig

Additional interface that can be implemented by the AtlasConfig instance providing knobs for internal registry details.

Classes in this package are only intended for use internally within spectator. They may change at any time and without notice.

Method Summary

static EvaluatorConfig	fromAtlasConfig(AtlasConfig config) Create a new instance from an AtlasConfig.
default Function<com.netflix.spectator.api.Id,Map<String,String>>	idMapper() Function to convert an id to a map of key/value pairs.
default <T> QueryIndex.CacheSupplier<T>	indexCacheSupplier() Supplier for cache to use within the evaluator query index.

Method Detail

fromAtlasConfig

static EvaluatorConfig fromAtlasConfig(AtlasConfig config)

Create a new instance from an AtlasConfig.

evaluatorStepSize

long evaluatorStepSize()

Step size used for the raw measurements.

commonTags

Map<String,String> commonTags()

Returns the common tags to apply to all metrics reported to Atlas.

idMapper

default Function<com.netflix.spectator.api.Id,Map<String,String>> idMapper()

Function to convert an id to a map of key/value pairs.

indexCacheSupplier

default <T> QueryIndex.CacheSupplier<T> indexCacheSupplier()

Supplier for cache to use within the evaluator query index.

parallelMeasurementPolling

default boolean parallelMeasurementPolling()

Returns true if the measurements should be polled in parallel using the default common fork join pool. For apps that are mostly just reporting metrics this can be useful to more quickly process them. Default is false.

delayGaugeAggregation

default boolean delayGaugeAggregation()

Returns true if gauge aggregation should be delayed until downstream in the final eval step. In some cases such as running with an inline aggregator, the same gauge value may be reported to multiple instances resulting in it contributing to the aggregate multiple times. When delayed, the downstream eval step will receive all datapoints and dedup based on a hash to mimic all datapoints being at a single aggregator.
