We are using SDL Tridion 2013 at the Content Delivery side none of the log files are generating.

It is confirmed that all required jar files (logback-classic.jar, logback-core.jar, slf4j-api.jar, jcl-over-slf4j.jar) are in the lib folder and logback.xml is also configured properly. The path of the log folder is correct and the app-pool has full permissions on that folder.

    Any changes in logback.xml will not be picked up until the application restarts. Did you restarted it . – user584 Mar 4 '14 at 10:05

    Both app-pool and website restarted after the change. – Abdul Qadir Mar 4 '14 at 10:19
  • is your logfile path correct, is it at per enviroment variable TRIDION_HOME ? also Validate logback.xml file in some XML validator. i validated the xml provided by you, it seems fine. – Raj Kumar Mar 4 '14 at 11:11
  • logfile path is correct. – Abdul Qadir Mar 4 '14 at 11:48

    2013 does not use SLF4J anymore... – Nuno Linhares Mar 4 '14 at 15:03

ON is not a valid logback log level, although IIRC, using an invalid value for level will result in DEBUG logging, so I don't think this will cause you not to see any output.

You are right to check the file permissions assigned to the application pool account. I would suggest taking this line of enquiry further using Sysinternals procmon to check for any failed file access.

You should confirm that your logback config file is, as the header says, UTF8, and that it's well-formed.

One other known cause for logging not to work is that Java is broken. I recall that Java 6 update 29 displayed exactly this behaviour, and I'm fairly sure there have been other problematic versions.

Post is quite old but it might help someone else. The consolidated jar of activemq (activemq-all-5.14.3.jar) contains slf4j jar files as well which confilicts with the jar files already available in CD installation. For activemq add individual files of activemq from lib folder of activemq except slf4j and it will start working.

I think the level of the root is incorrect, try:

<root level="OFF">
