Description
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:
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) }
Then the user just has to do this in his logback.xml (or similar in log4j.xml):
<logger name="org.drools" level="trace"/>
