Yves Bastiand updated LOG4NET-253:
----------------------------------
Description:
Hi,
I have a C# solution that contains three executables. I have each of these
three executables sharing the same log4net configuration file. At startup of
each of the executable, they retrieve a logger (one logger per executable, as
per configuration file further below). When one of the executable performs
Log.GetLogger(<loggerName>), it creates all the rolling files instead of only
the one rolling file that is referred to as appender-ref in the executable's
logger configuration.
For instance, when I startup my sending daemon executable, it performs
Log.GetLogger("SendingDaemonLogger") which creates 3 files
Log/RuleScheduler.txt, Log/NotificationGenerator.txt and
Log/NotificationSender.txt instead of only the desired
Log/NotificationSender.txt.
Then when I startup another of the executables, for instance the rule scheduler
daemon, this other process cannot write in Log/RuleScheduler.txt because it has
been created and locked by the sending daemon process.
I am guessing that there may be three different solutions to my problem:
1. The GetLogger should only create the rolling file appenders that are
referenced in the config
2. I should have one config file per executable, this way each config file
could list only one rolling file appender and starting each of the executable
would not create the rolling files of the other daemons. I am however reluctant
to do this because some of the configuration (SMTP appender, console appender)
is shared between the daemons and I don't want to have duplicate copies to
maintain. Unless there is a way to have a config file including another one?
3. Maybe there is a way to configure the rolling file so that concurrent access
across processes is allowed? This solution still isn't perfect in my opinion
because any of the daemons should not be creating the rolling files of some
other daemons.
Thanks in advance for your help!
