Tu V. Tran 8d8e2fb5c9 KAFKA-8729, pt 1: Add 4 new metrics to keep track of various types of invalid record rejections (#7142) ... Right now we only have very generic FailedProduceRequestsPerSec and FailedFetchRequestsPerSec metrics that mark whenever a record is failed on the broker side. To improve the debugging UX, I added 4 new metrics in BrokerTopicStats to log various scenarios when an InvalidRecordException is thrown when LogValidator fails to validate a record: -- NoKeyCompactedTopicRecordsPerSec: counter of failures by compacted records with no key -- InvalidMagicNumberRecordsPerSec: counter of failures by records with invalid magic number -- InvalidMessageCrcRecordsPerSec: counter of failures by records with crc corruption -- NonIncreasingOffsetRecordsPerSec: counter of failures by records with invalid offset Reviewers: Robert Yokota <rayokota@gmail.com>, Guozhang Wang <wangguoz@gmail.com>		2019-09-04 12:46:30 -07:00
