+## Optional RTR report metrics input
+
+If a separately deployed RTR service on the same host continuously writes `rtr-source-*`, `rtr-runtime-*`, and `rtr-clients-*` JSON reports, configure:
+
+```bash
+RTR_REPORT_DIR=/root/rpki/report
+RTR_REPORT_CONTAINER_DIR=/var/lib/ours-rp/rtr-report
+```
+
+The `artifact-metrics` container mounts the host directory read-only and reads it through `RPKI_METRICS_RTR_REPORT_DIR`, producing `ours_rp_rtr_*` metrics. By default, `RTR_REPORT_DIR` points at an empty fallback directory under the installer data root, so the metrics container also starts cleanly without an RTR service.
