I had been wondering the same thing, so I
finally decided to take a look @ the Drools source.
These log message are provided by the
SystemEventListener interface. There’s no direct way (that I can see) in
the code to set and enforce an actual “log level” (Someone please
tell me I’m wrong here.. I’d love to do this differently!)
What you need to do is implement your own
SystemEventListener implementation to override the default one. Before you do
anything meaningful with Drools, you’ll want to override the default by
calling:
SystemEventListenerFactory.setSystemEventListener(<YOUR
SystemEventListenerImpl>);
Here’s a basic no-op listener:
new SystemEventListener () {
public void debug(String
arg0) { }
public void debug(String
arg0, Object arg1) {}
public void
exception(Throwable arg0) {}
public void exception(String
arg0, Throwable arg1) {}
public void info(String
arg0) {}
public void info(String
arg0, Object arg1) {}
public void warning(String
arg0) {}
public void warning(String
arg0, Object arg1) {}
};
In reality what you probably want to do is
hook in your application’s logger here so it will respect the same log
levels the rest of your application runs under.

KnowledgeAgent Log Level
Hi,
I'm wondering if there is a way to manipulate the log level for the
KnowledgeAgent. Currently, I'm getting dumps to the console that I'd like
to control:
[2009:09:253 17:09:371:info] KnowledgAgent applying ChangeSet
[2009:09:253 17:09:371:debug] KnowledgeAgent subscribing to resource=[ClassPathResource path='mx/ecosur/multigame/impl/manantiales.drl']

[2009:09:253 17:09:372:debug] KnowledgeAgent ChangeSet requires KnowledgeBuilder

[2009:09:253 17:09:420:info] KnowledgeAgent new KnowledgeBase now built and in use
Thanks!
best wishes,
Andrew
