class specific logging level
Hi,
Is it possible to set logging level for few selected classes in appender to
DEBUG and rest all ERROR ? Is there any combination of filter that can do
this ?

Posted by Jacob Kjome <ho...@visi.com>.
How do you define your logger in your Java code? I'm suspicious that the
logger name you've defined as "MyClass" is merely the simple name of the
class, not the fully qualified name of the class that you've likely defined it
for your logger name.
That is, if "MyClass" is in the package "com.mypackage", and you've defined
the logger using something like...
Logger logger = Logger.getLogger(MyClass.class);
OR
Logger logger = Logger.getLogger(MyClass.class.getName());
...then your configuration should be....
<logger name="com.mypackage.MyClass">
<level value="DEBUG" />
</logger>
Note that "additivity" is "true" by default and need only be specified if you
want to set it to "false" (which would mean you wouldn't inherit
appenders/levels from ancestor loggers).
Also note that "priority" is the deprecated name for "level". It will work
the same, but you should just use "level" to avoid confusion.
Finally, you mention you want all other classes to log at the ERROR level, yet
you defined the level in "root" as INFO. Typo?

Re: class specific logging level

I will try setting root level to ERROR. All the other config is as u
suggested. Will try to debug why MyClass DEBUG logs arent getting logged
when its logger level is DEBUG. Thanks for detailed description.

Re: class specific logging level
Posted by Jacob Kjome <ho...@visi.com>.
First, you are not setting the level of the appender, but that of the logger
which can reference any given appender, including your named "Log1" appender.
So, if you want ERROR level for all classes, then set the "root" logger level
to ERROR.
After that, you make a decision of which appenders you want logging to go to
(disregarding level, as that is the job of the logger - except in regard to
more advanced configuration where you can set appender level thresholds or use
filters, but that's beyond our discussion here). If you want output of all
classes (again, disregarding level) to go to the "Log1", then you provide a
reference to "Log1" in the primordial "root" logger.
After that, if you want to lower the level for specific loggers, you can
specify those as you've done with "com.pkg.MyClass". Now all classes,
including "com.pkg.MyClass" will log at the ERROR level, but "com.pkg.MyClass"
will also provide DEBUG, INFO, and WARN (and SEVERE) logging as well.
This is all very standard stuff. If you don't experience the above behavior,
then I would suspect that the Log4j configuration you think you are using
isn't being used at all. You might want to use...
-Dlog4j.debug=true
This will tell Log4j to report how it is being configured. You may find that
some other configuration is being used instead of yours. Either that, or you
are not describing what you want clearly enough.

Re: class specific logging level
Posted by aggarwal <ak...@gmail.com>.
If I set the level of Log1 appender to DEBUG, then DEBUG logs of all the
classes including MyClass are getting logged. If I set it to ERROR, then
ERROR logs of all the classes including MyClass are getting logged. But what
I want is - DEBUG logs of only MyClass and ERROR of rest all. Here, my
motive is to set DEBUG level logging for most important classes helping in
debugging procedure.
<logger name="com.pkg.MyClass">
<level value="DEBUG" />
</logger>
private final static Logger logger = Logger.getLogger(MyClass.class);
This is how a logger is defined in my code. It was my mistake to replace
"com.pkg.MyClass" with "MyClass".
Thanks for "additivity" and "priority" related suggestions.
Actually, root isn't my concern here. No matter what the level of root and
appender is, I want DEBUG logs of only MyClass.

If you set the level of the Log1 appender to DEBUG, you say that you get
the DEBUG logs of Myclass in log1.log. Isn't that what you want?
Re: class specific logging level
Posted by aggarwal <ak...@gmail.com>.
Hi,
I have tried it with the following configuration :
<appender name="Log1" class="org.apache.log4j.RollingFileAppender">
<layout class="org.apache.log4j.PatternLayout">
</layout>
</appender>
<logger name="MyClass" additivity="true">
<level value="DEBUG" />
</logger>
<root>
<priority value="INFO" />
<appender-ref ref="Log1" />
</root>
I want MyClass logs of DEBUG level and all other classes of ERROR in
"log1.log" file as mentioned in logger "Log1". But it isnt happening. Am not
getting any DEBUG logs in "log1.log" whereas if I set the level in appender
"Log1" to DEBUG, I do get the DEBUG logs of Myclass in log1.log. I am sorry
if am still making some mistake here. Please correct me where am I wrong.
Thanks for such quick replies.

What I've provided does exactly what you are asking for. Setting your class
logging level to DEBUG overrides the inherited level from root for the
specified logger name. Why don't you just try it and see what it does rather
than speculate on why you believe it wouldn't work? You can also read try
reading the docs...

Due to some reason, the following text isn't visible in the message but is
when m replying back to this message.
<appender name="Log2" class="org.apache.log4j.RollingFileAppender">
<layout class="org.apache.log4j.PatternLayout"/>
</appender>
I have to work on RollingFileAppender only.

Re: class specific logging level
Posted by aggarwal <ak...@gmail.com>.
So, I found out the why RollingFileAppender wasn't behaving like
ConsoleAppender. Because I had mentioned a threshold level in
RollingFileAppender but not in ConsoleAppender. Removing threshold tag from
RollingFileAppender worked.

I think I have found the solution to my problem.
This thing is working with "org.apache.log4j.rolling.RollingFileAppender"
but not with "org.apache.log4j.RollingFileAppender"
Thanks for helping me out. :)

Re: class specific logging level

root being set to ERROR will not block the Myclass DEBUG; the
more-specific Myclass logger setting overrides the root setting.
Have you actually tried this?
package com.pkg;
import org.apache.log4j.Logger;
import com.other.OtherClass;
public class MyClass {
static Logger logger = Logger.getLogger(MyClass.class);
public static void main (String[] args) {
logger.error ("MyClass error");
logger.info ("MyClass info");
logger.debug ("MyClass debug");
OtherClass.doThings();
}
}
--
package com.other;
import org.apache.log4j.Logger;
public class OtherClass {
static Logger logger = Logger.getLogger(OtherClass.class);
public static void doThings () {
logger.error ("OtherClass error");
logger.info ("OtherClass info");
logger.debug ("OtherClass debug");
}
}

Re: class specific logging level
Posted by aggarwal <ak...@gmail.com>.
So when root level is ERROR and i set Myclass level to DEBUG, how will the
Myclass's DEBUG logs get logged since the root level is ERROR and it will
block the DEBUG logs ? What i know is that, if I set root level to DEBUG and
some particular class (say Myclass) logger level to ERROR then, all classes'
logs of DEBUG will get logged but not of Myclass as its restricted to ERROR.
But what I want is the vice-versa. I want ERROR level of all classes and
DEBUG of only few important classes. I am new to log4j so maybe what i am
sayin is wrong.

If you name your loggers by class name, then sure. This is standard logging
configuration, not some extra special workaround.
<logger name="com.mypackage.Myclass">
<level value="debug"/>
<!-- inherits A1 appender from root, applies only to com.mypackage.MyClass
-->
</logger>
<logger name="com.myotherpackage">
<level value="debug"/>
<!-- inherits A1 appender from root, applies to all classes in
"com.myotherpackage" -->
</logger>
<root>
<level value="error"/>
<appender-ref ref="A1"/>
</root>
