Whenever new pods are up, we get the new pods' metadata from the main Kubernetes API immediately. But, the metrics API takes some time to render data for the new pods (continues showing data for older pod). We were waiting for these two API's response. Ideally, if we have the metadata (name, status etc) of pods, we should show that to the users instead of "Loading Pods View".

Also, whenever there was any error in metrics API or the main API , we were throwing error "Failed to get pods details". This was caused mainly because of metrics API, as soon as we set up a pipeline and call it due to the same reason as mentioned above.
