func WithCardinalityLimit ¶

func WithCardinalityLimit(limit int) Option

WithCardinalityLimit sets the cardinality limit for the MeterProvider.

The cardinality limit is the hard limit on the number of metric datapoints that can be collected for a single instrument in a single collect cycle.

Setting this to a zero or negative value means no limit is applied.

func WithExemplarFilter ¶

func WithExemplarFilter(filter exemplar.Filter) Option

WithExemplarFilter configures the exemplar filter.

The exemplar filter determines which measurements are offered to the exemplar reservoir, but the exemplar reservoir makes the final decision of whether to store an exemplar.

By default, the exemplar.SampledFilter is used. Exemplars can be entirely disabled by providing the exemplar.AlwaysOffFilter.

func WithReader ¶

func WithReader(r metric.Reader) Option

WithReader associates Reader r with a MeterProvider.

By default, if this option is not used, the MeterProvider will perform no operations; no data will be exported without a Reader.

func WithResource ¶

func WithResource(res *resource.Resource) Option

WithResource associates a Resource with a MeterProvider. This Resource represents the entity producing telemetry and is associated with all Meters the MeterProvider will create.

By default, if this Option is not used, the default Resource from the go.opentelemetry.io/otel/sdk/resource package will be used.

func WithView ¶

func WithView(views ...metric.View) Option

WithView associates views with a MeterProvider.

Views are appended to existing ones in a MeterProvider if this option is used multiple times.

By default, if this option is not used, the MeterProvider will use the default view.
