Disable INFO logs in aws kcl - Kinesis

Question

I'm running on Ubuntu 16.04 & Java 8. kcl generate thousands of INFO log lines. Does any one know how to enable only ERROR and WARN logs?

*I have also the same question for kpl.

I don't have a logfile.

You disable using your application logging config, which you have not described. — kdgregory, Feb 18 '18 at 11:48
I dont have one. But how do I disable logs only from specific lib? Can you please provide an answer? — Stav Alfi, Feb 18 '18 at 12:05

<configuration>
    .........

    <logger name="com.amazonaws.services.kinesis.producer" level="warn"/>
    <logger name="com.amazonaws.services.kinesis.clientlibrary" level="warn"/>

    .........
</configuration>

Log levels: https://www.slf4j.org/api/org/apache/commons/logging/Log.html. You can also define a prefix of packages.

Sorry I don't remember. it was a long time ago. I think it is the logger configuration file, but I'm not sure. – Stav Alfi Mar 16 '22 at 05:07

If you are using the V2 AWS SDK/KCL libraries, consider the following.

Put this in your logging config file:

<logger name="software.amazon.kinesis" level="INFO"/>
<logger name="io.netty.handler" level="INFO"/>

or use this to reduce the full AWS SDK debug logs:

<logger name="software.amazon" level="INFO"/>
<logger name="io.netty.handler" level="INFO"/>

Either way, this will reduce the output significantly.
