Logging from same class to 2 different log files and each configu red with its own level

[De Moor Dries <dr...@awe.be>]

Hello,

In the application I'm writing I need to log 2 things. 
First of all information to a log file called app.log ( ERROR, DEBUG, INFO,
... )
Secondly I have to log some information into a file cumul.log  ( only INFO)

I thought to  define 2 separate property files bu I think this won't work.
I might be better to define two appenders but how to set the log levels. 
And how to prevent that ERROR, DEBUG INFO log messages end up in the
CUMUL.log file.


Any advice on this topic. Maybe I'm totally wrong?


Kind regards,


Dries

Unless you really want to manually process the file...
Smthg like :
    cat app.log | grep INFO >  cumul.log


I think you are better to use to different loggers.
Naming them should take into consideration why you want to make this 
differenciation.
We push ALL the SQL's  going tru' a sort of SQL-pooler to a special 
'sql.log', but I created a special entry in the hierarchy to have that:
<snip>
    Logger log = Logger.getLogger (this.getName ().getClass ());
    Logger sql = Logger.getLogger (this.getName ().getClass () + ".sql");
</snip>


Thomas,
