Hello Sheng Wu, Thanks for the quick patch for it.
For 3, I have already configured Rover agent as mentioned in the document and still it doesn't show any data for 'Deployment' and 'Namespace'. Any help would be appreciated.

Envoy logs are not getting displayed for the services in dataplane. 3. Namespace and deployment counts are not shown. There are 6 namespaces and many deployments are created in that cluster. 4. In Kubernetes, service section, apart from Overview menu, other menus TCP, HTTP, Topology, Pods, etc. are not displaying any data. Note: There is no error in the open telemetry collector pod. RBAC is set as expected. Regards, Senthilnathan A M BQ_END
