Viktor Somogyi-Vass updated KAFKA-7981:
---------------------------------------
Description:
In some occasions we detected errors where replica fetcher threads or log
cleaners died because of an unrecoverable error and caused more serious issues
in the brokers (from lagging to offline replicas, filling up disks, etc.). It
would often help if the monitoring systems attached to Kafka could detect these
problems early on as it would allow a prompt response from the user and the
greater possibility of capturing the root cause.
