> So far we have been focusing on Prometheus scraping Solr. In 9.x it would
> scrape the SolrPrometheusExporter. Now in 10.1+ we can point it directly at
> each solr node's prometheus compatible metrics endpoint.
> But many environments prefer OTEL / OTLP push of metrics rather than direct
> scrape. Problem is that OTEL metrics names have a different format than
> prometheus, so they are not compatible.
> We can solve this by a conversion stage. This Jira will deliver
> * The dev/ docker-compose stack will spin up an OTEL collector
> * A sample OTEL collector config with a metrics key converter thar serves
> the same prometheus keys as when scraping solr direclty (so dashboards will
> work), and that sets up an OTEL exporter instance that Prometheus can scrape
> * Configure prometheus to scrape the OTEL collector
> * Some ref guide documentation around the subject
