Jun Rao commented on KAFKA-4021:
--------------------------------
[~ewencp], those trace level logging only happens when there are broker
failures or restarts, which should be rare. If we do performance testing on a
steady cluster, the performance shouldn't be impacted.
> system tests need to enable trace level logging for controller and
> state-change log

> Key: KAFKA-4021
> URL: https://issues.apache.org/jira/browse/KAFKA-4021
> Project: Kafka
> Issue Type: Improvement
> Components: system tests
> Affects Versions: 0.10.0.0
> Reporter: Jun Rao
> Assignee: Geoff Anderson
>
> We store detailed information about leader changes at trace level in the
> controller and the state-change log. Currently, our system tests only collect
> debug level logs. It would be useful to collect trace level logging for these
> two logs and archive them if there are test failures, at least for
> replication related tests.
