---------------------------------
Assignee: Chuck Rolke
> C++ Broker Timer warnings are still too verbose and frequent
> ------------------------------------------------------------
>
> Key: QPID-4403
> URL: https://issues.apache.org/jira/browse/QPID-4403
> Project: Qpid
> Issue Type: Improvement
> Components: C++ Broker
> Affects Versions: 0.18
> Reporter: Chuck Rolke
> Assignee: Chuck Rolke
>
> Continuing issue QPID-3476.
> 1) Further reducing the timer warning message log level.
> Between 0.12 and 0.13 timer warning messages were demoted from warning to
> informational log levels. In 0.19 the external store produces overrun info
> messages every time leading to log file bloat.
> The proposal here is to demote the information statements to debug statements
> for the same reasons that they were demoted from warnings:
> "Demoting the warnings to debug statements would avoid undue alarm and
> prevent excess noise in log files. Should there be a need to see the
> information it is a lot easier to enable it (--log-enable debug+:Timer) than
> it is to turn it off at present."
> 2) Increasing the timer warning interval.
> Another consideration is to change the hard-coded five second warning
> interval to something longer. I suggest that one minute would be a good
> choice. The timer warning code already accumulates the number of warnings for
> the warning interval to prevent a flood of warnings. Increasing the warning
> interval further reduces the flood.
> 3) Performance improvement.
> When Issue 3476 was patched from warning to info there was a corresponding
> QPID_LOG_TEST in Timer.cpp that was not patched. This causes the late and
> overrun calculations to run even though the results will never be logged.
