OTLP Metrics Exporter is a Push Metric Exporter which sends metrics via the OpenTelemetry Protocol.

OTLP Metrics Exporter MUST support both Cumulative and Delta Temporality.

OTLP Metrics Exporter MUST allow Aggregation Temporality to be specified, as described in MetricExporter.

If the temporality is not specified, OTLP Metrics Exporter SHOULD use Cumulative as the default temporality.

The exporter MUST provide configuration according to the OpenTelemetry Protocol Exporter specification.

In addition, the exporter MUST provide the following configuration (note: this section will be merged to the OpenTelemetry Protocol Exporter specification once it reaches Stable):
