-TBD
+The `cdk-kurtosis` package also supports additional services to run alongside the network, you can find more details
+[here](https://github.com/0xPolygon/kurtosis-cdk/blob/main/docs/additional-services.md)
+
+The additional service called `observability` uses the following tools:
+- [panoptichain](https://github.com/0xPolygon/panoptichain)
+- [prometheus](https://prometheus.io/)
+- [grafana](https://grafana.com/)
+
+These tools mentioned above are already configured to extract important information from the network and provide it in a
+friendly dashboard that can be accessed via browser. The URL is exposed when the kurtosis package is initialized with
+the `observability` service enabled and here is how you can enabled it:
+
+````bash
+kurtosis run --enclave cdk github.com/0xPolygon/kurtosis-cdk '{"args": {"additional_services": ["observability"]}}'
+````
+
+Now that the environment is running, we can get the URL to access the observability dashboard by running:
+```bash
+kurtosis port print cdk grafana-001 dashboards
+```
+
+Access the dashboard URL in the browser and go to Menu > Dashboards > Panoptchain
+![grafana panoptchain menu](grafana_panoptchain_menu.png)
+
+Then you can start using the network and observe the following panels:
