I have a default tomcat installation with no change to the logging configuration. The log files (in particular catalina.out) appear to be getting rolled (daily) correctly.
However as well as the daily logs there is also a catalina.out file, which just continues to grow. This is what I need to fix, ie have it cleared daily (or remove it altogether if possible)
Can someone explain what is going on here and the best best strategy for controlling that log file size?
Just to clarify the output is being written to catalina.out and the daily log simultaneously
-rw-r--r-- 1 solr solr 90920663 Jul 18 01:16 logs/catalina.2009-07-18.log
-rw-r--r-- 1 solr solr 238010 Jul 18 01:16 logs/catalina.out
Setting swallowOutput appears to not make any difference.
The application being run under tomcat is solr in case that is relevant.
Fixed it, turns out the standard logging configuration defines a file logger and also a console logger. The file logger goes to the daily catalina log, and the console logger writes to catalina.out.
Fix was to change in conf/logging.properties:
to
That stops anything getting written to catalina.out
