What happened?

Description

The PRW exporter reports all HTTP errors as error_permanent="true" on otelcol_exporter_send_failed_metric_points_total, including 5xx responses. Those are backend failures, not data errors, so you can't use error_permanent to tell the difference between the backend being down and a tenant sending out-of-order samples.

Steps to Reproduce

Set service.telemetry.metrics.level: detailed on a collector with a PRW exporter pointing at a backend that returns 5xx. Send any metrics through it. Check otelcol_exporter_send_failed_metric_points_total, error_permanent="true" regardless of status code.

Expected Result

error_permanent="false" for 5xx responses, error_permanent="true" for 4xx.

Actual Result

error_permanent="true" for everything.

Collector version

v0.152.0
