My Logback pattern in logback.xml file as follows
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} ${LOG_LEVEL_PATTERN:-%5p} %yellow([%X{Auth-Scopes:-},%X{Auth-Principal:-},%X{Auth-Organization:-}]) %magenta(${PID:-}) --- [%15.15t] %cyan(%-40.40logger{39}) : %m %n ${LOG_EXCEPTION_CONVERSION_WORD:-%xEx}</pattern>
My problem is there is space in front of log lines from above pattern as follows
2021-08-18 03:40:00.017 DEBUG [test-service,,,] [,,] 1 --- [test-7] a.b.c.Test : Test
I am still trying to figure out what this cause for some time. Any help would be really appreciated .
Last parameter causes the problem.
You can try this one;
<Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} ${LOG_LEVEL_PATTERN:-%5p} %yellow([%X{Auth-Scopes:-},%X{Auth-Principal:-},%X{Auth-Organization:-}]) %magenta(${PID:-}) --- [%15.15t] %cyan(%-40.40logger{39}) : %m ${LOG_EXCEPTION_CONVERSION_WORD:-%xEx} %n</Pattern>

I am using Log4J along with Springboot in my J2EE based WebApp.
It throws illegal char <:> exception while processing Appender File.
Log4J version: 2.11.1
The logger properties in my application.properties file are as below
logging.pattern.console=%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{36} - %msg%n
logging.pattern.file=%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{36} - %msg%n
logging.file=log\\web.log
I understand that it's because of the character colon ':' , but even after trying out different patterns, I still get the same error message.
I don't know where the ${sys:LOG_PATH} part is coming from and how to fix this.
Can someone please help.
Attaching the error stack trace as well.
Thanks in advance :)
We have a SmtpAppender configured with a custom RateLimiter filter and ERROR log level, everything is working as expected except for the exceptions format, they are including the source code location which we would like to remove, we add such appender programmatically to each logger after the logging facility has been initialized, example of log:
2019-05-03 10:39:58,871 Thread-9 ERROR s.utils.Startup - Testing error
java.lang.RuntimeException: Testing error
at com.somepackage.SomeClass.lambda$enableEmailLogging$0(Startup.java:619) ~[classes/:?]
at java.lang.Thread.run(Thread.java:748) [?:1.8.0_212]
The ~[classes/:?] and [?:1.8.0_212] are annoying to us, also; in general we would like our logging to always include the exceptions which is well accomplished in our RollingRandomAccessFile appender as well, but having the same problem of stack trace source code location being included, here is also a snippet of our rolling file appender:
<Appenders>
<RollingRandomAccessFile name="RollingFile" fileName="/opt/tomcat/logs/some-webapp.log"
filePattern="/opt/tomcat/logs/some-webapp.log-%d{yyMMdd-HH}"
ignoreExceptions="false">
<PatternLayout>
<Pattern>%d{DEFAULT} %15.15t %-5p %15.15c - %m%n</Pattern>
</PatternLayout>
<Policies>
<TimeBasedTriggeringPolicy/>
</Policies>
</RollingRandomAccessFile>
</Appenders>
I have looked all over for a way to accomplish this with no luck.
Changing the PatternLayout's pattern from:
%d{DEFAULT} %15.15t %-5p %15.15c - %m%n
to
%d{DEFAULT} %15.15t %-5p %15.15c - %m%n%throwable
and removing the option ignoreExceptions from the appenders seem to accomplish what I wanted.
I already configured logback file to get classname, method name and line number.
<pattern> %d{HH:mm:ss.SSS} [%thread] %-5level %class{36}.%M %L - %msg%n </pattern>
I want to print log message when entering and existing method. How can i do that within the class using info() method. I used the code below. But it didnt print what i wanted.
I use org.slf4j.Logger and Logback logging
LOG.info("Entering " + );
This is what I got :
14:41:48.097 [main] INFO c.a.j.orgchart.CsvPersonReader - Entering
I want to print something like this:
14:41:48.097 [main] INFO c.a.j.orgchart.CsvPersonReader.[MethodName] [Linenumber] - Entering
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>INFO</level>
</filter>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %class{36}.%M %L - %msg%n</pattern>
</encoder>
</appender>
logging.pattern.console=%14date{dd.MM.yyyy kk:mm:ss.SSS} [%1level] %30.30logger{1}\.%replace(%replace(%replace(%caller{3..4}){'[\n\r]',''}){'\\(.+\\)$','()'}){'^.+\\.',''} : %msg%n
Above pattern outputs result like below:
10.05.2019 08:35:05.337 [INFO] epositoryConfigurationDelegate.forEach() : Bootstrapping Spring Data repositories in DEFAULT mode.
...
Here's another option if you want to printout little a bit polished version of it.
logging.pattern.console=%14date{dd.MM.yyyy kk:mm:ss.SSS} [%1level] %40.40logger{0}\.%-35.35replace(%replace(%replace(%caller{3..4}){'[\n\r]',''}){'\\(.+\\)$','()'}){'^.+\\.',''} : %msg%n
Output looks like this:
10.05.2019 08:45:57.228 [DEBUG] RepositoryConfigurationDelegate.forEach() : Bootstrapping Spring Data repositories in DEFAULT mode.
10.05.2019 08:45:59.651 [INFO] RepositoryConfigurationDelegate.forEach() : Finished Spring Data repository scanning in 384ms. Found 3 repository interfaces.

Just keep in mind that "...Generating the caller class information is

I'm having problems with my logging where slf4j doesn't log the filename and row number of the message/stacktrace.
Code:
private static Logger log = LoggerFactory.getLogger(SomeService.class);
#Override
public void aService(ServiceAdmin sa) throws Exception {
log.debug(LoggerFactory.class.toString());
log.debug(log.getClass().getName());
log.debug("Setup Example");
SomeService.setDefault(Example.getInstance());
log.debug("Example finished");
}
Log:
2015-04-20 14:47:26.573 DEBUG [main] null:-1 - class org.slf4j.LoggerFactory
2015-04-20 14:47:26.574 DEBUG [main] null:-1 - ch.qos.logback.classic.Logger

2015-04-20 14:47:26.575 DEBUG [main] null:-1 - SomeService finished
This is pars of my logback.xml that relates to this class
<logger name="com.bredband.nexusgw.services">
<level value="debug" />
<appender-ref ref="nexusservice" />
</logger>
<appender name="nexusservice"

Has anyone seen this before and can point me in the right direction?

-- Update --
I changed the %F to %C, but that didn't change anything in the logs. Then I tried to set debug = "on" in the javac header in my ant file and now it's logging classname and line number.
2015-04-21 08:28:55.910 DEBUG [main] Service.java:20 - class org.slf4j.LoggerFactory
2015-04-21 08:28:55.911 DEBUG [main] Service.java:21 - ch.qos.logback.classic.Logger

2015-04-21 08:28:55.912 DEBUG [main] Service.java:24 - Example finished
Although this is working, it's not something I've changed before. The only thing that has changed in this project over time is the addition of other external jars. I'm not really sure how adding a duplicate/newer/older version of slf4j in another external jar would affect the logging though, any version should look for the logback file?
-- Update --
After checking alot of historical checkins of the build.xml file I found that we actually had debug = "on" earlier and the problem may actually have been introduced by this parameter beeing set to "off".
Thank you for your help.

You should first make sure that you compile your application with debug information. If calling javac directly, then it is the -g command-line parameter. However most build tools (like maven or ant) have a specific way to provide this parameter.
You may also want to replace %F with %C, which should work without the debug information.
Hi I am a novice and the application I am currently coding for uses struts 1.2 and java. We currently use Log4j for log files but I need to implement SMTP Appender so that our errors are emailed to us.
I've tried everything to get errors to be emailed with no luck. Below is our log4j.properties file.
Any suggestions?
Thanks!

By default, the appender only sends an email when something is logged at the ERROR or FATAL levels.
As a side note, it appears that your threshold property may have improper case. I believe:
log4j.appender.mail.threshold=error
should be
log4j.appender.mail.Threshold=error
Edit...
Log4j can be put into debug mode by configuring the log4j.debug configuration property. This might provide some output regarding the SMTP appender.
Define the root logger in error level and override this for selected packages. The mail appender will remain in the error level.
