It looks like what the grafana stack does but it's linking specialized tools instead of building one big tool (eg linking traces [0]).

The only thing then is that there is no link between logs and metrics, but I guess since they created alloy [1] they could make it so logs and metrics labels match, so we could select/see both at once ?

Oh ok here's a blog post from 2020 saying exactly this: https://grafana.com/blog/2020/03/31/how-to-successfully-corr...

Yes, that's the LGTM(Loki, Grafana, Tempo, and Mimir) stack.

First, the main issue with this stack is maintenance: managing multiple storage clusters increases complexity and resource consumption. Consolidating resources can improve utilization.

Second, differences in APIs (such as query languages) and data models across these systems increase adoption costs for monitoring applications. While Grafana manages these differences, custom applications do not.
