Example 1 with NumberDataPoint

use of io.opentelemetry.proto.metrics.v1.internal.NumberDataPoint in project opentelemetry-java by open-telemetry.

the class MetricsRequestMarshalerTest method parse.

    // default values are not outputted), so we check that here. The output itself may have slightly
    // different ordering, mostly due to the way we don't output oneof values in field order all the
    // tieme. If the lengths are equal and the resulting protos are equal, the marshaling is
    // guaranteed to be valid.

    // numbers instead of names). This may improve in the future but what matters is what we produce
    // can be parsed.
