I want to manage log rotation on my server using logrotate, however Tomcat performs its own log rotation which interacts badly with logrotate, and I can't find a way to turn it off. My Tomcat instance currently produces 5 types of log:
After some googling I have discovered that I can disable rotation for the 'mysite' logs by adding rotatable="false"
into the appropriate <Value>
element in server.xml, but none of the other logs have corresponding <Value>
elements.
The logs seems to be configured by the logging.properties file, but I can't find a 'turn rotation off' option for this file. Can anyone help? I'm using Tomcat 8.5

There is option available in org.apache.juli.AsyncFileHandler to turn of the rotatable
functionality. You can directly add following param to disable to log rotation:
1catalina.org.apache.juli.AsyncFileHandler.rotatable = false

You can try using a different log handler and configure it to avoid rotation
Your properties file probably holds this configuration (if you haven't changed the default settings)
1catalina.org.apache.juli.AsyncFileHandler.level = DEBUG
1catalina.org.apache.juli.AsyncFileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.AsyncFileHandler.prefix = catalina.
You can change it to a java.util.logging.FileHandler
and disable the size limit for a rotation
1catalina.java.util.logging.FileHandler.level = DEBUG
1catalina.java.util.logging.FileHandler.pattern = ${catalina.base}/logs/catalina.%g.log
# set below limit to 0 !!
1catalina.java.util.logging.FileHandler.limit = 0
1catalina.java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter
From the docs
java.util.logging.FileHandler.limit
The maximum size of the file, in bytes. If this is 0, there is no limit. The default is 1000000 (which is 1 MB). Logs larger than 1MB roll over to the next log file
Since there is no limit, a file rotation will never occur.
