Hi!

I have been playing with logback for a couple of days and find a lot of its functionality amazing! I have a couple of questions that I was wondering if I could address!

I'm using logback to log information about a java server that I'm setting up. I want my log files to change every half hour and to never exceed 500MB. I would also like the logging system to cache 16MB of data before flushing to disk! Finally, I want the fileNamePattern to depend on the hostname where I'm running the server!

So this are my questions:
a. I have found a way for the log files to change every hour, but not every half hour... Is there a way to do this? Is there a way I can define my own RollingPolicy?
b. Is there a way for me to define the fileNamePattern somewhere else other than in the logback.xml file?
c. Is there a flush() function I can call when my server exists?

For b. I have tried something like:

LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
        Logger logger = lc.getLogger("ROOT");

        RollingFileAppender<ILoggingEvent> app = (RollingFileAppender<ILoggingEvent>)logger.getAppender("RootFileAppender");
        RollingPolicyBase rollingPolicy = (RollingPolicyBase)app.getRollingPolicy();
        rollingPolicy.stop();
        rollingPolicy.setFileNamePattern("bidderserver-%d{yyyy-MM-dd-HH:mm:ss}-"+hostname+"-ip.%i.log");
        rollingPolicy.start();

But that doesn't seem to work :(

I'm attaching my current logback.xml file.

Any and all help would be much appreciated!

Also, I tried visiting #qos.ch in freenode, but there's noone there except me!

Thanks again,
Daniel
