Aggregating different metrics in table panel

I am visualizing Prometheus metrics in Grafana. Right now I am able to display current value of the query as in the image.

I want to add another column with name Throughput which shall be the current value of another Prometheus query. The queries can be combined using endpoint label.

How to achieve this?

In case anyone else wonders, this article has a nice explanation on how to achieve that: Show multiple expressions for an instance in a Grafana table – Robust Perception | Prometheus Monitoring Experts

TL;DR

  1. create a Table panel, and define your queries. The key settings are that the Format should be Table , and the queries are Instant.
  2. in Transform do an Outer join on the instance label, and then Organize fields to hide and rename columns.
