Problem
NewRelic sink ( https://vector.dev/docs/reference/configuration/sinks/new_relic/ ) does not support .tags object, but instead of .tags, NR supports .attributes ( https://docs.newrelic.com/docs/data-apis/ingest-apis/metric-api/report-metrics-metric-api/ )
Remapping .tags to .attributes via VRL does not work.
Same metric from different sources ( where for example .tags.appname will be different ) shipped via the same Vector instance will be mixed in NR timeseries data. Querying metric based on .tags.appname metadata value would be impossible then.

Additionally, from taking a look at the new_relic sink, it appears that we don't send the metric type along, and that we don't handle distributions, either.
I'll open a separate ticket to track the lack of full metric support.
Opened #13781 to track further improvements to the metrics support for the new_relic sink.
@tobz distribution metrics are not actually supported by the New Relic Metric API. Internally, New Relic can handle this type of metrics (https://docs.newrelic.com/docs/data-apis/understand-data/metric-data/metric-data-type/), but the API only allows injecting gauge, count and summary metrics (https://docs.newrelic.com/docs/data-apis/ingest-apis/metric-api/report-metrics-metric-api/#send-metric-data). And regarding count metrics, pleas check out this discussion.
