Jason Gustafson updated KAFKA-7981:
-----------------------------------
Affects Version/s: (was: 2.3.0)
> Add Replica Fetcher and Log Cleaner Count Metrics
> -------------------------------------------------
>
> Key: KAFKA-7981
> URL: https://issues.apache.org/jira/browse/KAFKA-7981
> Project: Kafka
> Issue Type: Improvement
> Components: metrics
> Reporter: Viktor Somogyi-Vass
> Assignee: Viktor Somogyi-Vass
> Priority: Major
> Labels: kip
> Fix For: 2.5.0
>
>
> 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.
