Thanks Divij for the observations. KAFKA-15483 is added to address the missing metrics related to KRaft and ZK to KRaft migration. Please leave a comment at https://github.com/apache/kafka-site/pull/548 in which related metrics documentation is added.
https://issues.apache.org/jira/browse/KAFKA-15530 is raised to followup on the missing documentation of metrics introduced in KIP-890. ~Satish.
