In my adoc document, I want to show some output logging to the console.
Should I use [source], [source,shell] or nothing before the ----?

I'd argue it's not really source code (it's output) and I definitely don't output text that happen to contain shell language syntax to be code colored as shell language (because it's not).
You should use [source, console] for console commands and start with the $ sign to highlight the command. Lines without the $ sign after the command represent the output.
To disable source highlighting for a given source block, specify the language as text or remove the source style.
Alternatively, you can use [listing] for console output.
[source, shell] is used to highlight shell script files.
