Background

I have been for trying to make observer work for ages now without success. So in my search for alternatives, I found a hex package called observer_cli.

It is a library that once executed gives you all the information of the app like observer does, but via a CLI. This means I can put it in the production machine and see it live, without any pesky ssh tunnels nor anything. Like htop but for BEAM.

Problem

There are actually 2 problems:

1. This seems to require iex to run (all the examples use it) but the production machine does not have elixir, only erlang.
2. It is a library and needs to be inside a project.

Question

How do I turn observer_cli into a standalone executable that I can run in machine containing only erlang?

I have seen they have a escriptize but I don’t know what that means, nor do I understand the instructions (rebar3?)

Would appreciate some help.
