How to attach global attributes to metrics pipeline?

[ewoolsey]

My current meter provider looks like this:

    pub static ref METER_PROVIDER: MeterProvider = {
        opentelemetry_otlp::new_pipeline()
            .metrics(opentelemetry_sdk::runtime::Tokio)
            .with_exporter(
                opentelemetry_otlp::new_exporter().http(), // .with_export_config(export_config),
            )
            .with_resource(OTEL_RESOURCE.clone())
            .with_period(Duration::from_secs(60))
            .with_timeout(Duration::from_secs(15))
            .with_aggregation_selector(|kind: InstrumentKind| {
                match kind {
                    InstrumentKind::Counter
                    | InstrumentKind::UpDownCounter
                    | InstrumentKind::ObservableCounter
                    | InstrumentKind::ObservableUpDownCounter => Aggregation::Sum,
                    InstrumentKind::ObservableGauge => Aggregation::LastValue,
                    InstrumentKind::Histogram => Aggregation::ExplicitBucketHistogram {
                        boundaries: vec![
                            0.0, 5.0, 10.0, 25.0, 50.0, 75.0, 100.0, 250.0, 500.0, 750.0, 1000.0, 2500.0,
                            5000.0, 7500.0, 10000.0, 25000.0, 50000.0, 75000.0, 100000.0, 250000.0, 500000.0, 750000.0, 1000000.0
                        ],
                        record_min_max: true,
                    },
                }

            })
            .with_temporality_selector(DefaultTemporalitySelector::new())
            .build().unwrap()
    };

    pub static ref OTEL_RESOURCE: Resource = Resource::new(vec![
        KeyValue::new("service.name", env!("CARGO_PKG_NAME")),
        KeyValue::new("service.version", env!("CARGO_PKG_VERSION")),
        KeyValue::new("environment.name", env::var("ENV_ID").expect("ENV_ID"))
    ]);

when these metrics are sent to prometheus through the Otel collector the only information they retain is the service.name as the prometheus job. I would also like to be able to use the service.version and environment.name, but that information is apparently lost?

Ah found the answer! Solution is set resource_to_telemetry_conversion. Info is available here

I almost feel like this should be a standard default.
