+
+```bash
+# Port forward to Tempo query API
+kubectl port-forward -n monitoring svc/tempo 3200:3200
+
+# Access: http://localhost:3200
+```
+
+**Query traces via Grafana:**

+2. Select Tempo datasource
+3. Use TraceQL or search by service name
+
+**Verify Traefik is sending traces:**
+```bash
+# Check Traefik logs for OTLP export errors
+kubectl logs -n traefik-system -l app.kubernetes.io/name=traefik | grep -i "traces export"
+
+# Check Tempo is receiving data
+kubectl logs -n monitoring -l app.kubernetes.io/name=tempo | grep "receiver"
+```
+
+**Trace-to-log correlation:**
+- Click a trace span in Grafana → linked Loki logs appear (by namespace, pod, container)
+- Trace-to-metrics links to Prometheus by service name
