Match instruments: When an instrument matches a view, measurements received by that instrument will be processed. 2. Customize metric streams: A metric stream is identified by a match between a view and an instrument and a set of attributes. The metric stream can be customized by certain attributes of the corresponding view. The attributes documented next serve one of the previous two purposes. Args: instrument_type: This is an instrument matching attribute: the class the instrument must be to match the view. instrument_name: This is an instrument matching attribute: the name the instrument must have to match the view. Wild card characters are supported. Wild card characters should not be used with this attribute if the view has also a ``name`` defined. meter_name: This is an instrument matching attribute: the name the instrument meter must have to match the view. meter_version: This is an instrument matching attribute: the version the instrument meter must have to match the view. meter_schema_url: This is an instrument matching attribute: the schema URL the instrument meter must have to match the view. name: This is a metric stream customizing attribute: the name of the metric stream. If `None`, the name of the instrument will be used. description: This is a metric stream customizing attribute: the description of the metric stream. If `None`, the description of the instrument will be used. attribute_keys: This is a metric stream customizing attribute: this is a set of attribute keys. If not `None` then only the measurement attributes that are in ``attribute_keys`` will be used to identify the metric stream. aggregation: This is a metric stream customizing attribute: the aggregation instance to use when data is aggregated for the corresponding metrics stream. If `None` an instance of `DefaultAggregation` will be used. exemplar_reservoir_factory: This is a metric stream customizing attribute: the exemplar reservoir factory instrument_unit: This is an instrument matching attribute: the unit the instrument must have to match the view. This class is not intended to be subclassed by the user.
