I'm ready to merge this soon. Here is the email I intend to send to users list: > Subject: [ANNOUNCE] Solr 10.x OpenTelemetry Metrics System Declared BETA > > Hi Solr users, > > Solr 10.0 introduced a brand new metrics system based on OpenTelemetry (OTEL) instrumentation, replacing the Prometheus-style metrics and solr-exporter from Solr 9.x. The two systems are not backward compatible. > > As we have been working with the new metrics system post-release, we have identified areas that need stabilization before the API can be considered stable. In hindsight, we should have shipped this feature as BETA in 10.0 — we are correcting that now. > > **The OpenTelemetry-based metrics system is officially designated BETA as of Solr 10.0.** Metric names and other details may change in upcoming 10.x minor releases. All such changes will be clearly documented in the release notes. > > If you are on Solr 9.x, nothing changes for you. If you have already upgraded to 10.0 and are consuming the new OTEL metrics, please factor this in before treating the metric names as stable. > > The Reference Guide will be updated shortly with a BETA disclaimer. > > Thank you for your understanding. > > The Apache Solr PMC > -- This is an automated message from the Apache Git Service.
