[rules-users] Rules trace questions
Hello.
I'm trying to get the rules trace in execution by using
WorkingMemoryFileLogger. I am using the Hello word example, and I call the
WorkingMemoryFileLogger.wirteToDisk() in the RHS of rules. My modified drl
file is:
import com.sample.DroolsTest.Message;
global org.drools.audit.WorkingMemoryFileLogger rulesLogger
declare Output
@role (event)
end
rule "Hello World"
when
m : Message( status == Message.HELLO, myMessage : message )
then
System.out.println( myMessage + ": Hello message" );
m.setMessage( myMessage );
m.setStatus( Message.GOODBYE );
update( m );
end
rule "GoodBye"
when
Message( status == Message.GOODBYE, myMessage : message )
then
System.out.println( myMessage + ": Goodbye message" );
Output o= new Output();
insert(s);
end
rule "log trace"
when
o:Output( )
then
System.out.println("Loggin trace");
rulesLogger.writeToDisk();
end
I have filtered the logger to see only LogEvent.ACTIVATION_CREATED, and I
set the global rulesLogger in Main(). If I insert 2 messages, 2 "event.log"
files and one "test.log" appears. I have several questions (sorry if I say
nonsense):
First. How do I read the trace for each fire of "rule to log trace"? I mean,
the trace for "rule to log trace" is written forward (from event
insertion/updating/removing to "log trace" activation) or backward (from
"log trace" activation to event insertion/updating/removing)?
Second. Each event.log appears in each "log trace" activation because I am
writing the trace in the RHS. Am I right? Can I use that in order to read
the trace for each individual activation of "log trace"?
Third. I only allow LogEvent.ACTIVATION_CREATED, but some ObjectLogEvent
appear in the test.log file, but not in the event.log files. Why?
Thanks in advance.
