Deactivate logging in the Java-driver

[Ayman Nedjmeddine]

Hi,

The Java driver outputs some logging information when the connection to the database is established. I want that completely turn off.

Some replies on stackoverflow suggest that you can change the logging level by setting some System properties, then set the JUL to the wanted logging level.

What I did was this:

  System.setProperty("DEBUG.MONGO", "false");          
  System.setProperty("DB.TRACE", "false");             

  Logger.getLogger("com.mongodb").setLevel(Level.OFF); 

But that doesn't seem to have an effect.

So, how can I disable the logging output?

mongodb.version=3.0

mongodb.driver.version=3.0.0-beta3

Thanks!

Can you give an example of some of the logging output that you want to
suppress (the actual contents that are being printed out)?

Here's an example of it.  (screenshot attached)

Hi Ayman,

The 3.0.0 beta driver has switched to SLF4J for all logging.  The logging framework that you're using will dictate how you turn off logging.  See http://www.slf4j.org/manual.html#swapping to get started, and let me know if you need additional assistance.

Regards,

Jeff

Jeff,

What am I doing wrong?

My class path is: ".:./slf4j-nop-1.7.12.jar:./mongo-java-driver-3.0.0.jar"

I have a simple class that connects to my mongo db, but yet I still see:

Apr 06, 2015 8:03:33 AM com.mongodb.diagnostics.logging.JULLogger log
INFO: Opened connection [connectionId{localValue:1, serverValue:1236}] to iandev.sri.com:7777
Apr 06, 2015 8:03:33 AM com.mongodb.diagnostics.logging.JULLogger log
INFO: Monitor thread successfully connected to server with description ServerDescription{address=iandev.sri.com:7777, type=STANDALONE, state=CONNECTED, ok=true, version=ServerVersion{versionList=[2, 6, 9]}, minWireVersion=0, maxWireVersion=2, maxDocumentSize=16777216, roundTripTimeNanos=2544218}

I would really like to be able to turn of this.

Any advice?

Cheers, Ian.

I'm not sure Ian.

When I include the slf4j-nop artifact in my pom.xml I no longer see any output from the JULLogger or any other.

So for those folks that don't want to use Maven or an IDE, just rely on javac and java, is there a way to programmatically
turn off the logging?

[Jeff Yemin]

OK, I see the issue now.  Please try including slf4j-api-1.7.12.jar in your classpath, e.g

    java -classpath ".:./mongo-java-driver-3.0.0.jar:./slf4j-nop-1.7.12.jar:./slf4j-api-1.7.12.jar" Test

Otherwise the driver doesn't detect that SLF4J is present and falls back to JUL logging, so the no-op SLF4J logger is just being ignored.

I filed https://jira.mongodb.org/browse/JAVA-1746 to improve our docs for this.

Regards,

Jeff

Ah silence! Thank you.
