Can someone provide an example of how you would attach metadata to a process using metatdata/1? If I have a GenServer say that accepts messages with a user_id. Where would I add the user_id to the metadata so that it’s printed in the logging? I’ve been searching the docs and online, but feel I need …

Given the following entry in your config file: config :logger, :console, format: "[$level] $metadata$message\n", metadata: [:module, :function, :my_id] You can do the following; iex(1)> require Logger Logger iex(2)> Logger.info "test" [info] module= function= test :ok iex(3)> Logger.info "test"…
