MetricReader configuration scenarios
====================================

These examples show how to customize the metrics that are output by the SDK using configuration on metric readers. There are multiple examples:

* preferred_aggregation.py: Shows how to configure the preferred aggregation for metric instrument types.
* preferred_temporality.py: Shows how to configure the preferred temporality for metric instrument types.
* preferred_exemplarfilter.py: Shows how to configure the exemplar filter.
* synchronous_gauge_read.py: Shows how to use `PeriodicExportingMetricReader` in a synchronous manner to explicitly control the collection of metrics.

The source files of these examples are available :scm_web:`here <docs/examples/metrics/reader/>`.
