Ordered, because the level compares against them. trace is program flow, a message per iteration; debug is the completion of a secondary operation, or a detail worth keeping; info is the completion of the principal operation of a class or utility.

Class Method Details

.config ⇒ Object

Held by the configuration itself rather than here, because a class-level instance variable is not inherited: a subclass asking this class would answer nil.

  end
end

.log(*args, tag: nil, tags: nil) ⇒ Object

The keywords are named rather than swept up with the positionals: a method taking only *args accepts no keywords, so Ruby would fold them into a trailing hash and they would arrive as the message's data — which a handler hands to Rollbar as the exception.
