[Bela Ban (JIRA)]

Dynamically configure logging at runtime
----------------------------------------

                 Key: JGRP-484
                 URL: http://jira.jboss.com/jira/browse/JGRP-484
             Project: JGroups
          Issue Type: Feature Request
            Reporter: Bela Ban
         Assigned To: Bela Ban
            Priority: Minor
             Fix For: 2.4.1 SP3, 2.5


For performance reasons, JGroups caches log levels as follows:

boolean trace=log.isTraceEnabled();

// later:
if(trace) {
     log.trace(...);
}

While caching created a measurable performance increase, it also disabled the ability to change the log levels at runtime (example: JBoss' log4j.xml, which is re-read every 60 secs).

Investigate how to have both good performance and dynamic runtime configuration of log levels. E.g. signal to enable logging ?
