How to configure tomcat to rollover catalina.log files
Solution 1
org.apache.juli.FileHandler
does not support rotation based on file size and does not have the limit
and count
properties you are trying to set (see docs). Instead, you can use the standard Java java.util.logging.FileHandler which supports size-based rotation. You should change the following lines in your configuration:
handlers = 1catalina.java.util.logging.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
.handlers = 1catalina.java.util.logging.FileHandler, java.util.logging.ConsoleHandler
Also note that Java FileHandler
is configured slightly differently than Tomcat FileHandler
1catalina.java.util.logging.FileHandler.level = FINEST
1catalina.java.util.logging.FileHandler.pattern = <your log dir>/catalina%g.log
1catalina.java.util.logging.FileHandler.limit = 100000
1catalina.java.util.logging.FileHandler.count = 5
1catalina.java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter
However, I'm not sure that redirecting standard out to the file written by the logger will work well and help you achieve what you want.
Solution 2
According to the Official Tomcat 7 documentation :
public class FileHandler extends java.util.logging.Handler
Implementation of Handler that appends log messages to a file named {prefix}{date}{suffix} in a configured directory.
The following configuration properties are available:
directory - The directory where to create the log file. If the path is not absolute, it is relative to the current working directory of the application. The Apache Tomcat configuration files usually specify an absolute path for this property, ${catalina.base}/logs Default value: logs
rotatable - If true, the log file will be rotated on the first write past midnight and the filename will be {prefix}{date}{suffix}, where date is yyyy-MM-dd. If false, the file will not be rotated and the filename will be {prefix}{suffix}. Default value: true
prefix - The leading part of the log file name. Default value: juli.
suffix - The trailing part of the log file name. Default value: .log
bufferSize - Configures buffering. The value of 0 uses system default buffering (typically an 8K buffer will be used). A value of <0 forces a writer flush upon each log write. A value >0 uses a BufferedOutputStream with the defined value but note that the system default buffering will also be applied. Default value: -1
encoding - Character set used by the log file. Default value: empty string, which means to use the system default character set.
level - The level threshold for this Handler. See the java.util.logging.Level class for the possible levels. Default value: ALL
filter - The java.util.logging.Filter implementation class name for this Handler. Default value: unset
formatter - The java.util.logging.Formatter implementation class name for this Handler. Default value: java.util.logging.SimpleFormatter

I'm trying to configure my tomcat to rollover log files once a size limit is reached. I'm running tomcat as a windows service and am redirecting all my stdout to catalina.log. This is how I configured by logging.properties to set a size limit. But it is not working.
logging.properties
handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler .handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler ############################################################ # Handler specific properties. # Describes specific configuration info for Handlers. ############################################################ 1catalina.org.apache.juli.FileHandler.level = FINE 1catalina.org.apache.juli.FileHandler.directory = e:/apache-tomcat/logs/server_111-1001 1catalina.org.apache.juli.FileHandler.prefix = catalina. 1catalina.org.apache.juli.FileHandler.limit = 100000 # size 100kb 1catalina.org.apache.juli.FileHandler.count = 5 2localhost.org.apache.juli.FileHandler.level = FINE 2localhost.org.apache.juli.FileHandler.directory = e:/apache-tomcat/logs/server_111-1001 2localhost.org.apache.juli.FileHandler.prefix = localhost. 3manager.org.apache.juli.FileHandler.level = FINE 3manager.org.apache.juli.FileHandler.directory = e:/apache-tomcat/logs/server_111-1001 3manager.org.apache.juli.FileHandler.prefix = manager. 4host-manager.org.apache.juli.FileHandler.level = FINE 4host-manager.org.apache.juli.FileHandler.directory = e:/apache-tomcat/logs/server_111-1001 4host-manager.org.apache.juli.FileHandler.prefix = host-manager. java.util.logging.ConsoleHandler.level = FINE java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter ############################################################ # Facility specific properties. # Provides extra control for each logger. ############################################################ org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].handlers = 3manager.org.apache.juli.FileHandler org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].handlers = 4host-manager.org.apache.juli.FileHandler # For example, set the com.xyz.foo logger to only log SEVERE # messages: #org.apache.catalina.startup.ContextConfig.level = FINE #org.apache.catalina.startup.HostConfig.level = FINE #org.apache.catalina.session.ManagerBase.level = FINE #org.apache.catalina.core.AprLifecycleListener.level=FINE
But 1catalina.org.apache.juli.FileHandler.limit = 100000 doesn't seem to be working
