Hello,
(Java, Maven, Minecraft Paper 1.19.2)

Since i’ve upgraded mongodb-driver-sync to 4.7.2 my console have been spamming logs from

  • org.mongodb.driver.cluster
  • org.mongodb.driver.connection
  • org.mongodb.driver.client

Before i could go in the Loggers file and edit the

private static final boolean USE_SLF4J = false

and that fixed my problem.
Now i cant do that anymore.

What i currently have installed

  • slf4j-api: 2.0.4
  • log4j-api: 2.19.0
  • logback-classic: 1.4.5
  • log4j-slf4j2-impl: 2.19.0
  • morphia-core: 2.2.9
  • mongodb-driver-core: 4.7.2
  • mongodb-driver-sync: 4.7.2

I’ve installed those logging things but it still does not hide(not sure if im doing right) i read the documentation also but i don’t get it.

  • slf4j-api: 2.0.4
  • log4j-api: 2.19.0
  • logback-classic: 1.4.5
  • log4j-slf4j2-impl: 2.19.0

Tried to use this also but noting

<logger name="org.mongodb.driver.client" level="OFF" />

Logger.getLogger("org.mongodb.driver").setLevel(Level.OFF);

I don’t really want to downgrade again just to make the console hide.

Couple of questions:

  • Are you trying to disable all SLF4J-based logging, or just logging from the driver?
  • What version of the driver did you upgrade from?

  • What version of the driver did you upgrade from?

I actually had the mongo-java-driver: 3.12.4 installed. But now when i revert the changes it still prints the logging. Must be java then since i updated that also when i updated the drivers. But i used this to hide the logging Here

  • Are you trying to disable all SLF4J-based logging, or just logging from the driver?

Since i’m using the Listeners to log the connections i don’t really want the drive to print in the console that it connects to the server. So yes just the driver. I tried to use slf4j before but whatever i did, nothing happend.

 .applyToServerSettings(builder -> {
      builder.addServerMonitorListener(new MongoListener(this));
 });

But i do wish there was like an option to just add a line and the drive wont print anything in the console

MongoClientSettings.Builder options = MongoClientSettings.builder()
.disableLogging(true); //someting like this

I hope you understand what i mean :slight_smile:

I should have asked which logging system that you are actually using. But given what you have installed, it sounds like Log4J. Assuming that, what you should do is

  1. Remove any other SLF4J bridge library. From what I can tell, that would be logback-classic
  2. Configure log4j to disable all driver logging. Looking at Log4J documentation, that would look something like this
    <Logger name="org.mongodb.driver" level="off" additivity="false">
      <AppenderRef ref="Out"/>
    </Logger>

If you’re using a different logger than Log4J, it will be a bit different, but same idea.

Good luck,
Jeff

I removed the logback-classic.

Configure log4j to disable all driver logging. Looking at Log4J documentation, that would look something like this

I looked at the Log4J docs, i tested with the files log4j.xml and log4j2.xml inside the src/resource/
I compiled it to a .jar file after and the .xml file was there atleast, but it did not work either.
Do i need to write some code to make it work / did i put the files at wrong place?

This is the logging dependency’s i have now.

  • slf4j-api:2.0.4
  • log4j-api:2.19.0
  • log4j-core:2.19.0
  • log4j-slf4j2-impl:2.19.0

When i looked through the minecraft paper .pom files they had the libaries

  • slf4j-api:1.8.0-beta4
  • log4j-api: 2.17.1

Okey everything works until i add the minecraft paper inside the .pom.
Then it stops.

But… if i use the System.out.println(“test”); it has edited my output atleast
not it is 00:00:00 INFO]: [Plugin] [STDOUT] TEST
Before it was only 00:00:00 INFO]: [Plugin] TEST

My log4j2.xml right now

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="INFO">
    <Loggers>
        <Logger name="org.mongodb.driver" level="off" additivity="false">
            <AppenderRef ref="Out"/>
        </Logger>
    </Loggers>
</Configuration>

I tested with

  • org.mongodb.driver.client
  • org.mongodb.driver.*
