Migrating from log4j to log4j2
Hi all,
I am in a process of migrating an application from log4j1 to log4j2.
I have successfully migrated 98% of the application but I am stuck at a
point where it is required to alter the configurations of an Appender at
the run time.
Below is the piece of code that we used in log4j1
public void updateAppender(AppenderView view) {
auditLog.info("Updating the appender with the name : {}, of the
instance", view.getName());
AppenderSkeleton appender = (AppenderSkeleton)
LogManager.getRootLogger().getAppender(view.getName());
if (view.getPattern() != null) {
appender.setLayout(new PatternLayout(view.getPattern()));
}
if (!"null".equals(view.getThreshold())) {
appender.setThreshold(Level.toLevel(view.getThreshold()));
}
}
Since in log4j2, there is no method called setLayout and setThreshold in
Appender class, Can I know a way to implement the above functionality using
the log4j2 APIs.
Further I want to migrate the following piece of code,
else if (appender instanceof ConsoleAppender) {
ConsoleAppender consoleAppender = (ConsoleAppender) appender;
properties.put(CONSOLE_APPENDER_TARGET,
consoleAppender.getTarget());
properties.put(CONSOLE_APPENDER_ENCODING,
consoleAppender.getEncoding());
properties.put(CONSOLE_APPENDER_FOLLOW,
String.valueOf(consoleAppender.getFollow()));
}
Here I don't find getTarget,getEncoding,getFollow methods in
ConsoleAppender class.
Can some one please lead me to the way which I can implement the above
functionalities using log4j2 APIs.
Thanks,
Chathura

Yes Remoko, You are absolutely correct.

If I understand correctly, your users can modify the log configuration via a web interface? You can use the log4j 2 JMX MBeans to get the internal log4j status messages and display those to the users.

Re: Migrating from log4j to log4j2
Posted by Ralph Goers <ra...@dslextreme.com>.
No, you cannot change the layout of an existing Appender. You cannot change the level of the ThresholdFilter but you can remove the filter and replace it with a new one. You can do this with the removeFilter and addFilter methods. However, if you remove the filter then all events will go to the Appender until the addFilter is completed. If you add the new filter first then you probably would get closer to the behavior you want.
Keep in mind that Log4j 2 has a lot more immutable objects than Log4j 1 did so that you won’t run into cases where you might get exceptions or indeterminate behavior. That said, it should be possible to replace the layout in a safe way.
Also, I don’t know if it helps you at all, but Log4j 2 now supports PatternSelectors, so if you are using the PatternLayout but want multiple patterns depending on some criteria you can now do that just through configuration. So you could have a PatternSelector with n predefined patterns and have the user change a setting on which one he wants to use.

Hi,
That's not the way v2 works in general. Objects are usually immutable. You
need to reconfigure the system to update it. You can use the Configurator
API to update levels but for more serious work you can use the new builder
APIs introduced in 2.4.

Re: Migrating from log4j to log4j2
Posted by Chathura Widanage <ch...@adroitlogic.com>.
Gary,
Thank you very much.
Is there a way to setLayout and setThreshold of an appender at runtime
using log4j 2, like we used to do with log4j 1.
Thanks.

Setting the log level is a topic usually address by calling the
Configurator class.

Remoko,
Any idea on how to achieve that goal? We were able to do that using log4j

Re: Migrating from log4j to log4j2
Posted by Gary Gregory <ga...@gmail.com>.
For the console appender getting the encoding will look like:
Layout layout = consoleAppender.getLayout();
if (layout instanceof StringLayout) {
return ((StringLayout)layout).getCharset();
}

I added ConsoleAppender.getTarget() to git master. This is just a detail in
this conversation but I like the idea of being able to get this value of
our the console appender.

Re: Migrating from log4j to log4j2
Posted by Chathura Widanage <ch...@adroitlogic.com>.
We are developing a product(ESB) that will be used by an end user. In our
product we have provided an interface to alter the logging patterns
according the user preference in run time is self. We were able to do this
using log4j1. But I can't find a way to alter the pattern of appender in
run time using log4j2.
In case of Console appender, we want to collect information about the
appenders, so user can view them in a GUI which is provided by our product.
Please let me know if there is a possible way of doing these thing using
log4j2.
I would be glad if you can mention the log4j2 methods or procedures that
can be used to performs the exact same function of the following log4j1
methods.
setlayout
https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/Appender.html#setLayout(org.apache.log4j.Layout)
https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/AppenderSkeleton.html#setLayout(org.apache.log4j.Layout)
setThreshold
https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/AppenderSkeleton.html#setThreshold(org.apache.log4j.Priority)
getTarget
https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/ConsoleAppender.html#getTarget()
getEncoding
https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/ConsoleAppender.html#getFollow()
Thanks in advance

Re: Migrating from log4j to log4j2
Posted by Ralph Goers <ra...@dslextreme.com>.
I’m not sure what you are trying to do with the pattern is necessary. The latest version of Log4j supports a PatternSelector that should provide what you need.
I am not sure why the updating of the ConsoleAppender is necessary. Why can’t that just be configured?
