Alex Rudyy commented on QPID-8017:
----------------------------------
Keith's idea about propagation of log level configuration into JUL logger looks
like a reasonable one. It is essentially what
[LevelChangePropagator|https://logback.qos.ch/xref/ch/qos/logback/classic/jul/LevelChangePropagator.html]
does but we would need to have the logic implemented in [[InclusionRule]]s. I
think we can add an attribute for the rule like "propagateIntoJUL" where on
rule opening we would set the JUL log level as suggested by Keith
if"propagateIntoJUL" is true.

> Key: QPID-8017
> URL: https://issues.apache.org/jira/browse/QPID-8017
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.1, qpid-java-broker-7.0.0
> Reporter: Keith Wall
> Priority: Minor
>
> Reproduction:
> * Add {{NameAndLevel}} logger inclusion rule BrokerLogger {{file}} for source
> {{com.sleepycat.je.*}} with Level.ALL
> * Add a BDB HA VHN/VHN
> * Expected behaviour: verbose logging from JE. Actual behaviour: moderate
> logging only
> For instance, JE writes the following message at {{FINE}} which should be
> logged by the handler as {{TRACE}} but it is absent.
> {noformat}
> 2017-11-07 10:42:15,467 TRACE [Cleaner-1] (c.s.j.c.UtilizationCalculator) -
> [default] Clean file none: predicted min util is below minUtilization,
> current util min: 20 max: 20, predicted util min: 20 max: 20
> {noformat}
> There is a workaround for the functional problem, albeit a restart is
> required and the ability to change the process's system properties. Use the
> normal JUL system property {{java.util.logging.config.file}}. Set this to
> the location of a logging.properties file with the {{com.sleepycat.je}}
> logger set to the desired level. Once the JVM is restarted, the Broker's log
> files will include the logging.
