Geoffrey De Smet created JBRULES-3702: ----------------------------------------- Summary: Log message when a rule is fired (RHS is called) when logging level is TRACE Key: JBRULES-3702 URL: https://issues.jboss.org/browse/JBRULES-3702 Project: Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: drools-core (expert) Reporter: Geoffrey De Smet Assignee: Mark Proctor 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} -- This message is automatically generated by JIRA.
