DO NOT REPLY [Bug 46483] Truncating the end of the log message using

It appears to be behaving as documented:
<p>This behavior can be changed using the <em>maximum field
width</em> modifier which is designated by a period followed by a
decimal constant. If the data item is longer than the maximum
field, then the extra characters are removed from the
<em>beginning</em> of the data item and not from the end. For
example, it the maximum field width is eight and the data item is
ten characters long, then the first two characters of the data item
are dropped. This behavior deviates from the printf function in C
where truncation is done from the end.
This sounds really more like a usage question and not a bug. Please ask on
log4j-user on how best to accomplish end of field truncation.

The same principle should work, set the level of the logger to the
lower level and the threshold of the appender with the higher level.
log4j.logger.Logger1=DEBUG,Appender1,Appender2
log4j.appender.Appender2.threshold=ERROR

Hi, thanks for your answer.
But your solution is if I will have only two appenders.
That does not serve me because I have more than two appenders, then if I
change the root logger, the others appenders and loggers can be broken.
I need a solution without changing de rootLogger.
My application have many loggers and appenders.
How can I do?

What you want to accomplish is:
Attach both appenders to the root logger, set the level for the root
to debug and set the threshold of appender2 to ERROR.
log4j.rootLogger=DEBUG,Appender1,Appender2
log4j.appender.Appender2.threshold=ERROR
....
The only difference from your description is that both ERROR and FATAL
messages will go to Appender2. If you really only wanted ERROR, you
could apply a filter to Appender2, but that is more complicated and
likely this solution is sufficient.

Hi, thanks for your answer.
But your solution is if I will have only two appenders.
That does not serve me because I have more than two appenders, then if I
change the root logger, the others appenders and loggers can be broken.
I need a solution without changing de rootLogger.
My application have many loggers and appenders.
How can I do?
