Alex Rudyy updated QPID-8017:
-----------------------------
Attachment: 0001-QPID-8017-Broker-J-Propagate-logger-rule-log-levels-.patch
I attached a patch with changes allowing to propagate logger rules into JUL. I
think the patch should work as it is. Though, we have another small issue in
{{org.apache.qpid.server.store.berkeleydb.logging.Slf4jLoggingHandler}}. I did
not realize that we are substituting the log levels of the log records coming
from JE:
{code}
static
{
Map<Level, MappedLevel> map = new HashMap<>();
map.put(Level.SEVERE, ERROR);
map.put(Level.WARNING, WARN);
//Note that INFO comes out at DEBUG level as the BDB logging at INFO
seems to be more of a DEBUG nature
map.put(Level.INFO, DEBUG);
map.put(Level.CONFIG, DEBUG);
map.put(Level.FINE, TRACE);
map.put(Level.FINER, TRACE);
map.put(Level.FINEST, TRACE);
map.put(Level.ALL, TRACE);
LEVEL_MAP = Collections.unmodifiableMap(map);
}
{code}
As result, adding a rule {{com.sleepycat.je.*}} enabling {{INFO}} log level
does not bring the desired effect, as {{Slf4jLoggingHandler}} would be logging
je {{INFO}} logs with {{DEBUG}} log level but that is not enabled:) More over,
enabling log level {{ALL}} for {{com.sleepycat.je.*}} would make all JE logs to
be logged with {{TRACE}} log level regardless of the original log level set by
JE. It seems more work is required in {{Slf4jLoggingHandler}}. I would remove
log level mapping and instead add the logger rule for {{com.sleepycat.je.*}}
enabling {{WARN}} log level by default. I am pausing this work until we agree
on the changes required to be made in {{Slf4jLoggingHandler}} and whether
they should be made as part of {{7.0.1}}.

> Key: QPID-8017
> URL: https://issues.apache.org/jira/browse/QPID-8017
> Project: Qpid
> Issue Type: Bug
> Components: Broker-J
> Affects Versions: qpid-java-6.1, qpid-java-broker-7.0.0
> Reporter: Keith Wall
> Priority: Minor
> Fix For: qpid-java-broker-7.0.1
>
> Attachments:
> 0001-QPID-8017-Broker-J-Propagate-logger-rule-log-levels-.patch
>
>
> 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.
