[erlang-questions] Observability

[Gergely Buday]

Hi,

I came across a white paper on observability by Wavefront people, a
marketing material:

"Guide to Finding and Resolving Microservices Bottlenecks with Modern
Observability"

I was curious whether there are tools for observability in Erlang. I have
found this page:

https://erlef.org/wg/observability

and this empty github repository:

https://github.com/erlef/eef-observability-wg

What is the state of the art for observability tools for Erlang / BEAM
languages?
