Log4j not printing lower levels than WARN and creating no log files

I have the following log4j2.properties file

# Root logger option
log4j.rootLogger=DEBUG, stdout

## Direct log messages to file
log4j.appender.fileout=org.apache.log4j.FileAppender
log4j.appender.fileout.File=/logs/bbt_${current.date}.log
log4j.appender.fileout.ImmediateFlush=true
log4j.appender.fileout.Threshold=info
log4j.appender.fileout.Append=false
log4j.appender.fileout.layout=org.apache.log4j.PatternLayout
log4j.appender.fileout.layout.conversionPattern=%5p | %d | %m%n

# Direct log messages to terminal
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.conversionPattern=%5p | %d | %m    %n

and the following temporary test class

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

public class Temp {
    private static Logger log = LogManager.getLogger();

    public static void main(String[] args) {
        log.error("error");
        log.debug("debug");
        log.info("info");
        log.fatal("fatal");
        log.trace("trace");
        log.warn("warn");
    }
}

However, when I run the test class I get the following output:

11:32:19.295 [main] ERROR Temp - error

11:32:19.298 [main] FATAL Temp - fatal

Additionally, no /logs/ folder or log files are created. I thought the issue with the log levels might be caused by the fact that I'm setting a treshold in the first block (for the file), but commenting out this block makes no difference. Does anyone have an idea what could be the cause here?

It looks to me like you've used a properties file from Log4J version 1, but are trying to use Log4J version 2.

This version 2 properties file, named as log4j2.properties on the classpath, worked for me:

name=PropertiesConfig

rootLogger.level=debug
rootLogger.appenderRefs=stdout, file
rootLogger.appenderRef.stdout.ref=StandardOutput
rootLogger.appenderRef.file.ref=LogFile

appenders=console, file

## Direct log messages to file
appender.file.type=File
appender.file.name=LogFile
appender.file.fileName=logs/bbt_${current.date}.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=%5p | %d | %m%n

# Direct log messages to terminal
appender.console.type=Console
appender.console.name=StandardOutput
appender.console.layout.type=PatternLayout
appender.console.layout.pattern=%5p | %d | %m    %n
