Edoardo Comar commented on KAFKA-4981:
--------------------------------------
as per comments on the pull request, the 'prepared' metric may be better called
'authenticated' and will have a 0 flat rate for PLAINTEXT listeners.

Prepared doesn't convey much meaning in terms of an externally visible metric.
I imagine you chose it rather than authenticated since you intended it to work
for PLAINTEXT. But PLAINTEXT doesn't go through this if-block since
channel.ready() returns true.
