    LGTM

> Metrics view is a pure frontend feature, where several API calls are made to generate
the metrics view tabular data. In very large environments, rendering of these tables can take
a lot of time, especially when there is high latency. The improvement task is to reimplement
this feature by moving the logic to backend so metrics calculations happen at the backend
and final result can be served by a single API request.
