[Building Sakai] About Log4j

Happily, logging levels can now also be specified in sakai.properties. This augments and overrides the levels set in the default config file. Example:

log.config.count=3
log.config.1 = ALL.org.sakaiproject.log.impl
log.config.2 = OFF.org.sakaiproject
log.config.3 = DEBUG.org.sakaiproject.db.impl

This uses the established (but awkward) method of having a name.count followed by name.1, name,2, etc. to form an array of strings for the value "name". In this case, the name is "log.config". The values are of the form LEVEL.logger, and the possible levels are: OFF TRACE DEBUG INFO WARN ERROR FATAL ALL.

As you can see, Sakai uses log4j for logging. See the official log4j documentation for more information about how to configure it if you have questions.

Subject: [Building Sakai] About Log4j

Hi All.

I want to know if exists a way to change the Log4J log level, the objective is to display only ERROR messages.

I readed the documentation in confluence and works fine with kernel change, but our deployment is complete and we don't want to recompile the kernel again because we consider is a property.

I want to know if exists a workaround to do that, maybe with java_opts? Maybe the file can be overwritten in tomcat?

Thanks in advance, Miguel.
