When waiting for metrics, GitLab appears stuck
Summary
There does not exist any visual indicator that GitLab is attempting to gather metrics when we navigate to the metrics screen. We get backdrop with a message indicating we are waiting, but nothing indicating that we are actively making progress towards successfully retrieving those metrics. A lack of anything showing progress will attribute to a poor user experience and the thought that GitLab is stuck, which potentially leads to the user retrying, and for metric heavy dashboards, this may put unnecessary load on the server hosting those metrics.
Steps to reproduce
Navigate to a project that has the Prometheus Integration configured with dashboards, follow this up by navigating to the metrics screen.
What is the current bug behavior?
What is the expected correct behavior?
It would be preferred that we have a visual indicator that let's us know that we are making progress in retrieving the necessary data on the screen.
