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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
