How to disable Snowflake JDBC INFO logs flooding the Run console in Talend Studio R2025-06v3?

Erik516 — Wed, 09 Jul 2025 08:01:23 GMT

Hi,

After upgrading to Talend Studio R2025-06v3, my Run console is constantly flooded with INFO logs from the Snowflake JDBC driver, like connection session details every few seconds. These logs clutter the console and make it hard to track real job output.

Is there a way to disable or reduce the verbosity of these Snowflake INFO logs in Talend Studio?
I’ve looked for log level settings but can’t find a clear way to suppress these specific JDBC logs.

Any advice on where to configure or disable this logging would be appreciated!

Thanks in advance.

Hi @Erik516

I'm not sure this will work, but inside your studio (also in your TMC under Run profiles) you have JVM parameters. Go to Run tab -> Advanced settings -> JVM Parameters

add these 2 parameters (one row for each)

-Dorg.slf4j.simpleLogger.defaultLogLevel=warn -Dorg.slf4j.simpleLogger.log.net.snowflake=warn

I found the commands here : https://www.slf4j.org/api/org/slf4j/simple/SimpleLogger.html

Hi @quentin-vigne , thanks for the reply. I already tried that (as suggested by ChatGPT), but unfortunately it didn’t work.

What type of log4j level do you use ?

If you are using "info" it might override those jvm parameters

Alternatively try

-Dorg.slf4j.simpleLogger.log.net.snowflake=off
-Dorg.slf4j.simpleLogger.defaultLogLevel=off

Hello,

you can test to add :

-Dnet.snowflake.jdbc.loggerImpl=net.snowflake.client.log.SLF4JLogger

Hi @quentin-vigne , using =off does not work. log4jlevel is not checked, I don't know if it is using "info" level by default.
