Disable logging from SDKs/jars in scala

I am using logback.xml for logging. I want to disable the logs from 3rd party jars/SDKs. For this I used the log level="OFF" for that jar, but still the logs are getting logged. Next I tried using the same log level for one of my files in codebase, I was able to disable the logs for my file.

Below is my logback config :

'''

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern> Some pattern </pattern>
    </encoder>
</appender>

<logger name="<sdk file path>" level="OFF"/>         !--- This doesn't work ---!    
<logger name="<file from my codebase>" level="OFF"/>  !--- This works ---!

<root level="INFO">
    <appender-ref ref="STDOUT"/>
</root>
'''

A library can use any name it likes for a logger so the name will not necessarily match the path of the library.

The %logger field in the pattern gives the name of the logger so you will see the actual name in the logging output. If you see output that you want to suppress, use the name from the log (or a prefix) in the logger element.

I would also recommend setting the root to the lowest level and then increasing the level for the specific libraries that you are interested in.

<logger name="myloggername" level="DEBUG"/>

<root level="ERROR">
    <appender-ref ref="STDOUT"/>
</root>
