We Keep Coding

log4j2 in Tomcat8 App works in IDE (Eclipse) but not in Production environment (RHEL8)

I have a Tomcat 8.5 Webapp that I've developed. In Development I run Tomcat (8.5) via my IDE (Eclipse), and the logging configuration is picked up from WEB-INF/classes/log4j2.properties
When I build the War and deploy to our RHEL8 servers running Tomcat8.5, there is no log file created at all.
I presume there is some kind of classpath difference that's leading to this behaviour; but how do I diagnose the issue?
Included in my WebApp are the logging jars:
log4j-core-2.15.0.jar
log4j-jcl-2.15.0.jar
log4j-api-2.15.0.jar
log4j-1.2-api-2.15.0.jar
slf4j-api-1.5.8.jar
slf4j-log4j12-1.5.8.jar
I've tried logging in my app using both:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
...
private static final Logger log = LoggerFactory.getLogger(ApplicationConfiguration.class);
log.info("Application Initialised");
and:
import org.apache.log4j.Logger;
public static Logger log = Logger.getLogger(DashboardBean.class);
log.info("Test");
but neither one results in the file being created
log4j2.properties:
name=PropertiesConfig
property.filename = tms.log
appenders = rolling
appender.rolling.type = RollingFile
appender.rolling.name = RollingFile
appender.rolling.fileName = ${filename}
appender.rolling.filePattern = tms-backup-%d{yyyy-MM-dd}-%i.log.gz

LogManager ClassNotFoundException when upgrade Log4j to Logj42

I should upgrade my projects log4j to log4j2.So i deleted log4j dependencies and add log4j2.Some project worked well but one project get error as follow:

I am initializing the logger as below
private static final org.apache.logging.log4j.Logger LOG = org.apache.logging.log4j.LogManager.getLogger(SSLServer.class.getName());
When I start the standalone Java application using the main() am getting below error and server.log file is not created, I did some research regarding the below error and most of the articles were referring to log4j2.xml configuration and none of the config changes worked in my log4j2.properties
log warn: org.apache.logging.log4j.status.StatusLogger - No Root logger was configured, creating default ERROR-level Root logger with Console appender
No Root logger was configured, creating default ERROR-level Root logger with Console appender

Few things to look at:
make sure you don't have any other log4j2 config files on your classpath. The list is not small and can trip up. See it in the documentation here.
get debug info out of log4j2 by increasing status messages: status = info (debug or trace )
remove log4j2. as the prefix from all your properties so that log4j2.appender.console.type = Console becomes appender.console.type = Console
add file logging to your rootlogger: rootLogger.appenderRef.rolling.ref = LogToFile

I adapted your configuration to work. Please check this out:
# Print configuration errors only
status=error
# Console appender
appender.console.type=Console
appender.console.name=LogToConsole
appender.console.layout.type=PatternLayout
appender.console.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
# Rotate log file
appender.rolling.type=RollingRandomAccessFile
appender.rolling.name=LogToRollingRandomAccessFile
appender.rolling.fileName=${SERVER_HOME}/logs/server.log
appender.rolling.filePattern=logs/${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz
appender.rolling.layout.type=PatternLayout
appender.rolling.layout.pattern=%d %p %C{1.} [%t] %m%n
appender.rolling.policies.type=Policies
appender.rolling.policies.time.type=TimeBasedTriggeringPolicy
appender.rolling.policies.size.type=SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=1KB <-- for testing only!
appender.rolling.strategy.type=DefaultRolloverStrategy
appender.rolling.strategy.max=10
# Root logger
rootLogger.level=info
rootLogger.appenderRef.console.ref=LogToConsole
rootLogger.appenderRef.rolling.ref=LogToRollingRandomAccessFile
Please make sure you have the SERVER_HOME variable in your environment.

I don't see where you are declaring a root logger in you log4j.properties file.
I see, at the bottom, where you are setting the "level" on the rootlogger but I don't see where you've established the rootLogger.
My log4j.properties file start out like this:
log4j.rootLogger=WARN, FILE, CONSOLE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %5p %20t %25F:%L - %m%n

I think you need two modifications in your properties configuration:
Remove the prefix "log4j2."
Remove the space after "appender.rolling.type =
RollingRandomAccessFile "
Also check if your package name is correct:
logger.app.name = com.ssl.server
status = error
appender.console.type = Console
appender.console.name = LogToConsole
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
#appender.file.type = File
#appender.file.name = LogToFile
#appender.file.fileName=logs/app.log
#appender.file.layout.type=PatternLayout
#appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
# Rotate log file
appender.rolling.type = RollingRandomAccessFile
appender.rolling.name = LogToRollingRandomAccessFile
appender.rolling.fileName = logs/server.log
appender.rolling.fileName = ${server.home}/logs/server.log
appender.rolling.filePattern = logs/$${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d %p %C{1.} [%t] %m%n
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=10MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 10
# Log to console and rolling file
#logger.app.type = AsyncLogger
logger.app.name = com.ssl.server
logger.app.level = info
logger.app.additivity = false
logger.app.appenderRef.rolling.ref = LogToRollingRandomAccessFile
logger.app.appenderRef.console.ref = LogToConsole
rootLogger.level = info
rootLogger.appenderRef.stdout.ref = LogToConsole

How do I print IST in log file using log4j2?

I want to print IST in my log file using log4j2. Currently it is printing time in UTC. Below is my log4j2.properties file.
name = log4j2
appenders = console, file
appender.file.type = File
appender.file.name = LOGFILE
appender.file.fileName=/home/dockerdev/code/stmtParser/log/fcu_analyzer.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = EnhancedPatternLayout
appender.console.layout.pattern = %d{yyyy-MM-dd HH:mm:ss}{IST} %-5p %c{1}:%L - %m%n
loggers=file
logger.file.name=/home/dockerdev/code/stmtParser/log4j2.properties
logger.file.level = info
logger.file.appenderRefs = file
logger.file.appenderRef.file.ref = LOGFILE
rootLogger.level = debug
rootLogger.appenderRefs = file ,stdout
rootLogger.appenderRef.file.ref = LOGFILE
rootLogger.appenderRef.console.ref = STDOUT
This I am trying to run in local docker. Log generated from this shows UTC. How can i get IST ? what change is required?

Try change timezone inside your Dockerfile

I got the solution, since i was using log4j2 I had to only add {IST} after date pattern for file appender. So final properties file which would print IST in log file is
appender.file.type = File
appender.file.name = LOGFILE
appender.file.fileName=/home/dockerdev/code/stmtParser/log/fcu_analyzer.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS}{IST} [%t] %c{1} - %msg%n

log4j does not log for file

I am using log4j to log to both console and file. It just works with console, but not with file, thought the file is being created
This is my configuration file:
name=PropertiesConfig
property.filename = logs
appenders = console, file
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
appender.file.type = File
appender.file.name = LOGFILE
appender.file.fileName=${filename}/my_server_logs.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n
loggers=file
logger.file.name=guru.springframework.blog.log4j2properties
logger.file.level = debug
logger.file.appenderRefs = file
logger.file.appenderRef.file.ref = LOGFILE
rootLogger.level = debug
rootLogger.appenderRefs = file, stdout
rootLogger.appenderRef.stdout.ref = STDOUT
What am I missing please?

The connection between file appender and root logger is missing.
Add the following line at the bottom of your properties file:
rootLogger.appenderRef.file.ref = LOGFILE
It will work as expected.

I think you expect that the variable ${filename} be substituted with the value of property.filename.
Can you try to substitute ${filename} with a hard path and try again (E.g: 'C:\' on Windows or '/tmp/' on Unix-like).
