Subject [jira] [Created] (ZOOKEEPER-2921) fsyncWarningThresholdMS is applied on each getChannel().force() - also needed on entire commit

Jordan Zimmerman created ZOOKEEPER-2921:
-------------------------------------------

             Summary: fsyncWarningThresholdMS is applied on each getChannel().force() - also
needed on entire commit
                 Key: ZOOKEEPER-2921
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2921
             Project: ZooKeeper
          Issue Type: Improvement
          Components: server
    Affects Versions: 3.5.3
            Reporter: Jordan Zimmerman
            Priority: Minor


FileTxnLog.commit() has a warning when an individual sync takes longer than {{fsyncWarningThresholdMS}}.
However, it would be more useful to warn when the entire commit operation takes longer than
{{fsyncWarningThresholdMS}} as this can cause client connection failures. Currently, commit()
can take longer than 2/3 of a session but still not log a warning.
