Grafana 9.1 introduces a new beta feature called "trace to metrics," enhancing the tool's capacity to correlate different telemetry signals by allowing users to navigate from a trace span to a selected data source, such as Prometheus. This feature enables users to quickly view trends or aggregated data related to each span by configuring tracing data sources, selecting tags to be included in linked queries, and mapping span attribute names to label names for valid metrics queries. Users can view these links in Grafana's Explore interface and execute queries with dynamically inserted span attribute values. The release encourages users to explore additional use cases, provide feedback, and join the Grafana community for further discussion, highlighting the ease of starting with Grafana Cloud's metrics, logs, traces, and dashboards.
