Questions about Chronicle Logger

[joaovictor720]

Hello,

First of all, I would like to apologize if this is not the appropriate space for asking the question below. Unfortunately, me and my team couldn't find any specific forums or documentation regarding Chronicle Logger other than https://javadoc.io/doc/net.openhft/chronicle-logger/4.0.0/index.html (which has little to no description of configuration and usage).

How to properly configure Chronicle Logger for performance?
@hendrikebbers also had some trouble in configuring/using this logger, as stated in issue #130. One PR was sent out to fix this on his repo, but it is not really clear what changes made it faster, since there was only one commit.

The main parts of our pom.xml are:

<dependency>
	<dependency>
		<groupId>net.openhft</groupId>
		<artifactId>chronicle-logger-log4j-2</artifactId>
		<version>4.26ea1-SNAPSHOT</version>
	</dependency>
	<dependency>
		<groupId>org.apache.logging.log4j</groupId>
		<artifactId>log4j-api</artifactId>
		<version>2.14.1</version>
	</dependency>
	<dependency>
		<groupId>org.apache.logging.log4j</groupId>
		<artifactId>log4j-core</artifactId>
		<version>2.14.1</version>
	</dependency>
	<!-- Other dependencies... -->
</dependencies>
<build>
	<!-- Resources... -->
	<plugins>
		<plugin>
			<groupId>org.codehaus.mojo</groupId>
			<artifactId>exec-maven-plugin</artifactId>
			<version>1.2.1</version>
			<configuration>
				<mainClass>com.myproject.Main</mainClass>
				<jvmArgsAppend>
				<arg>--add-opens java.base/java.lang.reflect=ALL-UNNAMED --add-opens java.base/sun.nio.ch=ALL-UNNAMED --illegal-access=permit --add-exports java.base/jdk.internal.ref=ALL-UNNAMED</arg>
				</jvmArgsAppend>
			</configuration>
		</plugin>
	</plugins>
</build>

Our Log4j's configuration file (log4j2.xml) is:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration  status="WARN">
	<Appenders>
		<File  name="MainFileAppender"  fileName="logs/mainlog.log">
			<PatternLayout>
			<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level- %msg%n</pattern>
			</PatternLayout>
		</File>
		<Chronicle  name="CHRONICLE">
			<path>logs</path>
			<chronicleCfg>
				<blockSize>256</blockSize>
				<bufferCapacity>512</bufferCapacity>
			</chronicleCfg>
		</Chronicle>
	</Appenders>
	<Loggers>
		<Logger  name="log4jlogger"  level="DEBUG">
			<appender-ref  ref="MainFileAppender"/>
		</Logger>
		<Root  level="DEBUG">
			<AppenderRef  ref="MainFileAppender"/>
		</Root>
		<Logger  name="chronicle"  level="trace"  additivity="false">
			<appender-ref  ref="CHRONICLE"/>
		</Logger>
	</Loggers>
</Configuration>

Is there any documentation we could check to clarify this issue?
