David Smiley commented on SOLR-17828:
-------------------------------------
Yes, 10. The Prometheus Exporter cannot consume metrics from Solr 10 since it
only consumed the javabin format from the /admin/metrics API. In 10, that
endpoint only exposes prometheus (aka "exposition") formatted metrics,
basically.

> Solr's Prometheus exporter is costly to maintain and with OTEL migration, the
> /admin/metrics endpoint will natively expose Prometheus/OpenMetrics so the
> exporter is no longer necessary or useful.
> In Solr 10, we should remove this exporter entirely and push users who want
> to decouple their metrics pipeline to external tools that either just scrape
> the /admin/metrics or use something that is OTLP compatible such as the OTEL
> Collector which Solr will support.
