I am wondering why Java Logging API is not displaying fine, finer, and finest messages.
Let's look at the following code:
logger.setLevel(Level.ALL);
logger.info("Level:" + logger.getLevel());
logger.severe("Some Fatal message%n");
logger.warning("Some WARN message%n");
logger.info("Some INFO message%n");
logger.fine("Some DEBUG message%n");
logger.finer("Some DEBUG message%n");
logger.finest("Some TRACE message%n");
I would expect this to display every log message, since I am specifying LogLevel.ALL in the first line.
However it is omitting the fine messages, this is what I see:
22-08-28 16:37:25.997 INFO [global] Level:ALL
22-08-28 16:37:26.025 SEVERE [global] Some Fatal message
22-08-28 16:37:26.025 WARNING [global] Some WARN message
22-08-28 16:37:26.026 INFO [global] Some INFO message
Why is it skipping the fine, finer, and finest, given that I have the level set to ALL?
You need to additionally set the level on the Handlers. Handlers are the things which take the actual log events and then push them to stdout, in your case.
logger.setLevel(Level.ALL);
for (Handler handler : logger.getParent().getHandlers()) {
handler.setLevel(Level.ALL);
}

When writing the logs of a war into payara server logs, it was not able to determine/identify the Logger name.
When I see it on the admin console, the Logger value us blank, and it is printing Log Level as SEVERE even it is just an INFO level log.
Following is the entry in payara server
Log Entry Detail
Timestamp : Mar 25, 2022 12:37:03.439
Log Level : SEVERE
Logger :
Name-Value Pairs : {levelValue=1000, timeMillis=1648211823439}
Record Number : 679
Message ID :
Complete Message : [http-thread-pool::http-listener-1(18)] INFO com.test.LogTest - com.test.LogTest
Sample code looks like the following
public class LogTest {
static Logger logger = LoggerFactory.getLogger(LogTest.class);
public static void main(String[] args) {
logger.info(logger.getName());
logger.debug("debug");
logger.info("info");
}
}
In my local I was able to get the following output
[main] INFO com.test.LogTest - com.test.LogTest
[main] DEBUG com.test.LogTest - debug
[main] INFO com.test.LogTest - info
I am using SimpleLogger (slf4j) as the logging library
Please help me on how to set the Logger value in the payara server logs, for the logs that I am logging
in my app i can upload files (max size is 10MB). I created an exception handler for too big files, but console still shows warning that there was a try to upload too big file:
2020-09-30 01:38:59.306 WARN 2476 --- [nio-8080-exec-3] .m.m.a.ExceptionHandlerExceptionResolver : Resolved [org.springframework.web.multipart.MaxUploadSizeExceededException: Maximum upload size exceeded; nested exception is java.lang.IllegalStateException: org.apache.tomcat.util.http.fileupload.impl.SizeLimitExceededException: the request was rejected because its size (26937892) exceeds the configured maximum (10485760)]
Exception handler:
#ExceptionHandler(MaxUploadSizeExceededException.class)
public void oversizedFilesHandler(MaxUploadSizeExceededException e){
accountService.writeExceptionToFile(e);
}
Is it possible to disable these warnings?
You can achieve that by adding log level to your properties file:
RULE : logging.level.xxxx=LEVEL
where:
LEVEL is one of TRACE, DEBUG, INFO, WARN, ERROR, FATAL, OFF.
xxxx is a package/class.
We apply the rule to your case:
logging.level.org.springframework.web=ERROR
Or even thinner:
logging.level.org.springframework.web.multipart =ERROR
Hence, only ERROR, FATAL and OFF level will be logged to you console.
I'm using log4j 2 with a pattern layout that highlights different log levels. In my code, I specify a custom level. When this level is logged, it's not colored and shows null before the level in the log. Below is my pattern and log snip.
Custom level:
final Level STATS = Level.forName("STATS", 510);
Pattern:
%highlight{%-10.10level}{FATAL=red, ERROR=red, WARN=yellow, INFO=green, DEBUG=blue, TRACE=blue, STATS=red}
Output:
Jul 22 15:36:00 INFO [qtp982337150-23] c.e.class : Logging an info line
Jul 22 15:36:00 nullSTATS [qtp982337150-23] c.e.class : Logging a stats line
You may have found a bug. Please raise this on the Log4j2 JIRA issue tracker.
I found the same problem with log levels from jul.
I filed an issue in jira for that: https://issues.apache.org/jira/browse/LOG4J2-2405
This seems to be the same problem.
UPDATE 2018-10-24:
I have prepared a Pull Request that fixes this problem. Hopefully this will be included in Log4j2 soon.
I have the following log4j configuration
log4j.rootLogger=ERROR, myappender1
log4j.appender.myappender1=org.apache.log4j.RollingFileAppender
log4j.appender.myappender1.File=D:/phase10/myLog1.log
log4j.appender.myappender1.MaxFileSize=10MB
log4j.appender.myappender1.MaxBackupIndex=10
log4j.appender.myappender1.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender1.layout.ConversionPattern=%m%n
log4j.appender.myappender2=org.apache.log4j.RollingFileAppender
log4j.appender.myappender2.File=D:/phase10/myLog2.log
log4j.appender.myappender2.MaxFileSize=10MB
log4j.appender.myappender2.MaxBackupIndex=10
log4j.appender.myappender2.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender2.layout.ConversionPattern=%m%n
log4j.logger.com.my.package=INFO, myappender2
log4j.addivity.com.my.package=false
After this I run app and see in both logs
INFO WARN ERROR messages.
Does my configuration wrong ?
expected result - in myLog1.log only ERROR messages
in myLog2.log INFO WARN ERROR messages.
If to replace log4j.addivity.com.my.package=false with log4j.addivity=false I see same result)
update
thanks #Kevin Tanzer
after replacing 'addivity' with 'additivity' In myLog1 I see no messages. in myLog2 I see all messages
All mesages logged from com.my.package
The last configuration item should be 'additivity' not 'addivity', which may be causing your problems. You've defined two separate appenders.
The myappender1 will have only ERROR (and FATAL) messages.
The myappender2 will get INFO, WARN and ERROR (and FATAL) messages because INFO is a lower severity than the others. That is, the order is:
TRACE,
DEBUG,
INFO,
WARN,
ERROR and
FATAL
I am using log4j properties to capture the logs.i wants to remove error info from INFO file.

Loggers may be assigned levels. The set of possible levels, that is:
TRACE,
DEBUG,
INFO,
WARN,
ERROR and
FATAL
are defined in the org.apache.log4j.Level class. Although we do not encourage you to do so,
you may define your own levels by sub-classing the Level class.
Level Inheritance
A logging request is said to be enabled if its level is higher than or equal to the level of its logger. Otherwise, the request is said to be disabled. A logger without an assigned level will inherit one from the hierarchy. This rule is summarized below.
Basic Selection Rule
A log request of level p in a logger with (either assigned or
inherited, whichever is appropriate) level q, is enabled if p >= q.
UPDATE:
In Log4j2 version 2.0.2
If you wish to change the root logger level, do something like this :
LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
Configuration config = ctx.getConfiguration();
LoggerConfig loggerConfig = config.getLoggerConfig(LogManager.ROOT_LOGGER_NAME);
loggerConfig.setLevel(level);
ctx.updateLoggers(); // This causes all Loggers to refetch information from their LoggerConfig.
I get some information from log4j filter
and read the log4j source code. I found it is possible.
Do like this:
appender.File.type=File
appender.File.name=infolog
appender.File.layout.type=PatternLayout
appender.File.layout.pattern=%d %p %C{1.} [%t] %m%n
appender.File.filename=${infologfilename}
#here! add filter named star, type is ThresholdFilter
appender.File.filter.star.type=ThresholdFilter
#level you want to filter
appender.File.filter.star.level=info
#if mathched the level, the log higher then the level will not output
appender.File.filter.star.onMatch=DENY
#if mismathed,output
appender.File.filter.star.onMisMatch=ACCEPT
May be it can help you.
I suggest you to use xml configuration,easy to read and edit.
