> 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!
