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...
