[QUESTION] How can we have a list of fields availables over the usable method's

[cmeschin]

Hi,
I would like to know which fields are provided by methods and articles.

Some standard fields are available and can be guessed as service.description or host.name but others are not ... like longoutput, notes_url, etc...

Where is the request who build and convert this values (integer in string such as "state_str")

thanks for your help.
