+description: 'Enable monitoring for Nakama with Jaeger and Prometheus'
+---
+
+<Note>
+  The Jaeger and Prometheus integration is only available in World CLI starting
+  from version v1.3.1.

+
+## Enabling Monitoring
+
+You can enable this feature, run the following command:
+
+```bash
+world cardinal start --telemetry
+```
+
+By default this will start both the [Jaeger](https://www.jaegertracing.io/) and
+[Prometheus](https://prometheus.io/) containers.
+
+You can access the Jaeger Web UI at `http://localhost:16686`:
