+#### Enable [Hubble Observability](https://github.com/cilium/hubble/)
+
+Cilium also provides the observability component for gaining deep insights into the network and security behavior of your applications.
+This also works with ROS and ROS 2 application containers.
+Hubble collects network flow data using eBPF and processes it to generate valuable insights, this data can be visualized and analyzed through the Hubble UI or using the Hubble CLI.
+
+We can just follow [Service Map & Hubble UI](https://docs.cilium.io/en/latest/gettingstarted/hubble/#hubble-ui) procedure to enable Hubble and the following graphical interface will come up.
