I am running 3.8.0 version of Zookeeper that uses logback.
Getting too many debug logs, In 7 hours it logged more than 300M worth of logs.

How to change the log level in 3.8.0 zookeeper?
I want to change some settings in the logback.xml. But I couldn't find a
default configuration and path of logback.xml inside the tar of
apache-zookeeper-3.8.0-bin.
I tried adding the default logback.xml but that doesn’t worked.
ZOO_CONF_DIR=/conf
ZOO_LOG_DIR=/logs
COPY logback.xml $ZOO_CONF_DIR/
COPY logback.xml $ZOO_LOG_DIR/
logback.xml
<configuration>
<property name="zookeeper.console.threshold" value="INFO" />
<property name="zookeeper.log.dir" value="." />
<property name="zookeeper.log.file" value="zookeeper.log" />
<property name="zookeeper.log.threshold" value="INFO" />
<property name="zookeeper.log.maxfilesize" value="256MB" />
<property name="zookeeper.log.maxbackupindex" value="20" />
<!--
console
Add "console" to root logger if you want to use this
-->
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L] -
%m%n</pattern>
</encoder>
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>${zookeeper.console.threshold}</level>
</filter>
</appender>
<root level="INFO">
<appender-ref ref="CONSOLE" />
</root>
</configuration>
