This is an issue to track the ongoing work to unify the way that metrics from Open Telemetry can get into Prometheus, including the four major possible write paths:

1. Prometheus Open Telemetry endpoint
2. Open Telemetry Collector PrometheusExporter
3. Open Telemetry Collector PrometheusRemoteWriteExporter
4. Open Telemetry GO SDK Prometheus Exporter

There are two main goals:

1. Unify the behavior of each component so they produce the same predictable results for a given set of inputs.
2. Unify, as best as possible, the configuration options in each component

Unification of behavior:

Work occurring in: https://github.com/prometheus/otlptranslator/

• otel/otel-spec: Update Prometheus spec based on new updates to UTF-8 and name translation in upstream Prometheus open-telemetry/opentelemetry-specification#4494
• otel/otel-go: Migrate prometheus exporter to use prom/otlptranslator for name translation open-telemetry/opentelemetry-go#6704
• otel/otel-collector-contrib: Migrate from pkg/translator/prometheus to prometheus/otlptranslator. open-telemetry/opentelemetry-collector-contrib#39822 (there are some remaining references to the old codepath in dependent projects, but the work in the collector itself is done)

Configuration Option tasks:

• prom/prom: feat: Support 'NoTranslation' mode in OTLP endpoint #16441
• prom/prom: Add documentation for 'NoTranslation' mode #16470
• otel/otel-collector-contrib: [exporter/prometheus] Implement Prometheus translation strategies. open-telemetry/opentelemetry-collector-contrib#35459 (depends on spec change being done)
• otel/otel-conf prometheus: Add Translation Strategy per SDK schema update open-telemetry/opentelemetry-configuration#261
• otel/otel-go: [Prometheus] Exporter should support Prometheus translation modes open-telemetry/opentelemetry-go#6668 (depends on spec change being done)

Other dependent work:

• otel/otel-collector-contrib: [exporter/prometheusremotewrite] Support Prometheus Remote-Write v2 open-telemetry/opentelemetry-collector-contrib#33661 (not required to close this bug)
