How can I silence logback?

[Theo]

I'm completely new to Akka, so there may be something obvious I'm
missing here. When I run my super-simple test application (basically
just creating an actor, sending it a message and exiting) I get 20
lines of annoying messages from logback and Akka. Is there any simple
way of making them go away? They don't tell me anything useful, and
the output from my app is completely swamped.

I build the app with SBT and I've placed a logback.xml file so that
it's in the classpath when I "sbt run". It's basically identical to
Akka's logback.xml, but I set the log level of the akka package to
WARN (which doesn't seem to have much effect).

If I remove the logback.xml file I don't get any messages from
logback, but I get more messages from Akka (I get debug messages).

This is the output when running my app:

You're not telling us how you're running your application.

If you run it in the microkernel, you can just edit the logback.xml file in /config and set the log level to WARN for akka.

If you want to make sure that logback is using a custom config file,
specify:

java -Dlogback.configurationFile=/path/to/config.xml chapters.configuration.MyApp1

when you run it.

Here's the link to the logback docs:

http://logback.qos.ch/manual/configuration.html



Does that help?

Cheers,

What I figured out is that from within sbt the logback-test.xml is
used. Try editing that one to a silence mode :)

The logback-test.xml shouldn't be in the dist, and if the users project is depending on Akka, no logback-test.xml should be present in the deps.
As I said earlier, it really helps if I know what environment/context it's used in. But that information is good for all people hacking on Akka itself :-)

I'm running the app with "sbt run" (which I mentioned), and the output
clearly states that logback does not find logback.groovy, logback-
test.xml, but that it finds logback.xml.

I managed to figure out that the problem was that it found multiple
configuration files (it was the same file that had been copied to
multiple locations by sbt, mostly because I had fiddled too much with
the settings), now logback is silent. however I still see these
messages (seems to be from some dependency of akka):

INF [20101104-08:29:56.829] api: Initializing GlobalStmInstance using
factoryMethod 'org.multiverse.stms.alpha.AlphaStm.createFast'.
INF [20101104-08:29:56.843] alpha: Created a new AlphaStm instance
INF [20101104-08:29:56.844] api: Successfully initialized

GlobalStmInstance using factoryMethod
'org.multiverse.stms.alpha.AlphaStm.createFast'.

the log format does not match the format in the logback config, so I
assume that this library uses some other logging framework. does
anyone know which, or how to make it log through logback so that I can
tell it to keep quiet?

just to show that it's definitely not going through logback, here's
the output if I set akka's log level to INFO:

[INFO] [2010-11-04 08:34:29,124] [run-main] a.c.ConfigLogger$: Config
[akka.conf] loaded from the application classpath.

INF [20101104-08:34:29.241] api: Successfully initialized

GlobalStmInstance using factoryMethod
'org.multiverse.stms.alpha.AlphaStm.createFast'.

and adding <logger name="org.multiverse" level="WARN"/> to logback.xml
does not work.

That is from Multiverse which is using Java Util Logging.
