Hello, You can create 2 appenders : - one for your specific file (only errors) and the other with all levels - use filters in the first one : http://logback.qos.ch/manual/filters.html the way the 1st appender log only the logs with level.isEquals error level Regards From: bertrand.dechoux-prestataire@bforbank.com To: logback-user@qos.ch Date: Fri, 19 Aug 2011 08:50:16 +0000 Subject: [logback-user] All error in a separate file Hi, I am new to logback configuration. I have read the online manual but clearly not in depth. I would like to log in a separate file all ERROR logs but keep these logs at the same time where they are supposed to be. I understand I could use root with an ERROR level and a file appender but then I woul lose all the details (logs lower than ERROR). Is there any obvious way that I might have missed?
