Is there a way to change the default log level of Hazelcast? - hazelcast

Question

I am trying to start the hazelcast using the default hazelcast.xml and the start script provide by hazelcast. I am setting the logging type to log4j2 in the hazelcast.xml. I am seeing this message in the logs.
ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'log4j2.debug' to show Log4j2 internal initialization logging.
I couldn't figure out the way to change the default log level. Could anyone help me on how to set the default log level?

This works for me,
export JAVA_OPTS="-Dhazelcast.logging.type=log4j2 -Dlog4j.configurationFile=./log4j2.xml"
And then have a file named log4j2.xml in the current folder containing
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
<Appenders>
<Console name="ConsoleRed" target="SYSTEM_OUT">
<PatternLayout pattern="%red{%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n}"/>
</Console>
<Console name="ConsoleWhite" target="SYSTEM_OUT">
<PatternLayout pattern="%white{%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n}"/>
</Console>
<Console name="ConsoleYellow" target="SYSTEM_OUT">
<PatternLayout pattern="%yellow{%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n}"/>
</Console>
</Appenders>
<Loggers>
<Logger name="com.hazelcast" level="info" additivity="false">
<AppenderRef ref="ConsoleYellow"/>
</Logger>
<Logger name="com.hazelcast.core" level="info" additivity="false">
<AppenderRef ref="ConsoleRed"/>
</Logger>
<Root level="error">
<AppenderRef ref="ConsoleWhite"/>
</Root>
</Loggers>
</Configuration>
If you have colours on, you'll see different colours for the different types of messages.
