[jboss-jira] [JBoss JIRA] (JBRULES-3702) Log message when a rule is fired (RHS is called) when logging level is TRACE

[Geoffrey De Smet (JIRA)]

    [ https://issues.jboss.org/browse/JBRULES-3702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740098#comment-12740098 ] 

Geoffrey De Smet commented on JBRULES-3702:
-------------------------------------------

This partially duplicates KnowledgeRuntimeLogger which is clunky to enable.
To enable KnowledgeRuntimeLogger, requires a programmatic change, not a configuration change.

I would argue: every Logger should be able to be enabled through normal logging configuration (= logback.xml, log4j.xml, ...).
Just like in any other framework (hibernate, weld, spring, ...)

So maybe for 6.0, we can replace KnowledgeRuntimeLogger by normal logging?

> On the user forum, I've often seen questions like this:
> "- Can I trace which rules are executed with what bounded variables and in which order"
> Debugging in the IDE's doesn't cut it (eclipse plugin is borked and intellij/netbeans doesn't support debugging DRL).
> Instead something like this in the code would help:
> {code}
> if (logger.isTraceEnabled() { // returns immediately => NO NOTICEABLE PERFORMANCE DELAY IN NON-TRACE MODE
>     List<...> boundedVariables = ...; // Retrieve bounded variables only in TRACE mode
>     logger.trace("  Rule fired with name ({}) and boundedVariables ({})", ruleName, boundedVariables)
> }
> {code}
> Then the user just has to do this in his logback.xml (or similar in log4j.xml):
> {code}
>   <logger name="org.drools" level="trace"/>
> {code}
