    aggregationSelector? aggregationTemporalitySelector? cardinalitySelector? metricProducers? otelComponentType?
    aggregationSelector?: AggregationSelector

    Aggregation selector based on metric instrument types. If no views are configured for a metric instrument, a per-metric-reader aggregation is selected with this selector.

    NOTE: the provided function MUST be pure

    aggregationTemporalitySelector?: AggregationTemporalitySelector

    Aggregation temporality selector based on metric instrument types. If not configured, cumulative is used for all instruments.

    NOTE: the provided function MUST be pure

    cardinalitySelector?: CardinalitySelector

    Cardinality selector based on metric instrument types. If not configured, a default value is used.

    NOTE: the provided function MUST be pure

    metricProducers?: MetricProducer[]

    Note, this option is experimental. Additional MetricProducers to use as a source of aggregated metric data in addition to the SDK's metric data. The resource returned by these MetricProducers is ignored; the SDK's resource will be used instead.

    otelComponentType?: string

    The component type used for reporting self-observability SDK metrics. This option is experimental and is subject to breaking changes in minor releases.
