-- To visualize the raw metrics stored on the Prometheus server (for debugging and local development use cases), use the built-in Prometheus UI at http://localhost:9090/graph. For example, http://localhost:9090/graph?g0.expr=traces_span_metrics_calls_total&g0.tab=0&g0.range_input=5m
+- To visualize the raw metrics stored on the Prometheus server (for debugging and local development use cases), use the built-in Prometheus UI at http://localhost:9090/query. For example, http://localhost:9090/query?g0.expr=traces_span_metrics_calls_total&g0.tab=0&g0.range_input=5m
