@vy Previously we were using log4j 1.x references for logging
(org.apache.log4j ) and log4j 2.x dependency (Log 4j 2.22.0). We were using
below code to make it compatible
```
private static void setLog4jCompatibility() {
// Migrating from Log4j 1.x to 2.x -
https://logging.apache.org/log4j/2.x/manual/migration.html
System.setProperty("log4j1.compatibility", "true");
}
```
Now, we updated our log4j 1.x references with log4j 2.x (
org.apache.logging.log4j) with same log4j 2.x dependency (Log 4j 2.22.0). Also
remove the above compatibility code.
With old log4j.properties files( mentioned below), we are not getting logs
on CONSOLE, though they getting logged properly in file
```
# root logger
log4j.rootLogger=INFO,CONSOLE,R
# appender
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.R=org.apache.log4j.RollingFileAppender
#log file location
log4j.appender.R.File=${LOG_DIR}/testLogs/teswizSampleTestLog.log
# layout and pattern
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%5p [%t] (%F:%L)- %m%n
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%d - %c -%p - %m%n
log4j.appender.R.Append=false
```
Also, tried updating to log4j2.properties file, but no logs are getting
logged at CONSOLE or FILE.
```
status = error
dest = err
name = PropertiesConfig
property.filename = ${LOG_DIR}/testLogs/teswizSampleTestLog.log
appenders = console, rolling
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%d{yyyy-MM-dd HH:mm:ss,SSS}] %-5p
[%c.%M()] (%t) %m%n
appender.rolling.type = RollingFile
appender.rolling.name = RollingFile
appender.rolling.fileName = ${LOG_DIR}/testLogs/teswizSampleTestLog.log
appender.rolling.filePattern = $%d{MM-dd-yy-HH-mm-ss}
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = [%d{yyyy-MM-dd HH:mm:ss,SSS}] %-5p
[%c.%M()] (%t) %m%n
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 2
appender.rolling.policies.time.modulate = true
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=100MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 5
rootLogger.level = info
rootLogger.appenderRefs = console, rolling
rootLogger.appenderRef.console.ref = STDOUT
rootLogger.appenderRef.rolling.ref = RollingFile
# The root logger with appender name
rootLogger = INFO, STDOUT
```
Also, using the PropertyConfigurator to configure both files
```
Path logFilePath = Paths.get(properties.get(LOG_PROPERTIES_FILE).toString());
configs.put(LOG_PROPERTIES_FILE, logFilePath.toString());
inputStream = Files.newInputStream(logFilePath);
PropertyConfigurator.configure(inputStream);
```
