I sow google log document.The google recommand to use logging.properties and use io.grpc and sun.net logging level is kept at INFO level

it is recommended that io.grpc and sun.net logging level is kept at INFO level, as both these packages are used by Cloud internals and can result in verbose / initialization problems.

io.grpc.netty.level=INFO
sun.net.level=INFO

I added logging.properties and -Djava.util.logging.config.file=/path/to/logging.properties.

io.grpc.netty.level=INFO
sun.net.level=INFO

But It didn't work, still print out too many logs.

How to set to not print out "DEBUG io.grpc.netty.shaded.io.grpc.netty.NettyClientHandler.log"? I am using logback.

This is my logback.xml

        <appender-ref ref="CLOUD" />
    </root>
</configuration>

Answer 1

I solved that through easy way. I only added this code in logback.xml.That is I changed log level of io.grpc.netty.shaded.io.grpc.netty to debug from info.

<logger name="io.grpc.netty.shaded.io.grpc.netty" level="info">
    <appender-ref ref="STDOUT" />
    <appender-ref ref="CLOUD" />
</logger>
