Hello Alan,
we have done something in the project where I am working
(the cooking recipe is also attached as a text file)
:
By default, Anthill Pro logs its messages to the main Tomcat log file, which is located at $CATALINAHOME/logs/stdout.log. In fact this file contains the messages which are printed on the console if Tomcat is started from the command line. In our case, Tomcat is started as a service and stdout and stderr are redirected to $CATALINAHOME/logs/stdout.log and $CATALINAHOME/logs/stderr.log. These files can grow in size occupying all the available disc space. The notes below provide a way to control their size.
Since Anthill Pro outputs lots of messages, its logs must be separated from Tomcat logs and some restriction must be imposed on their size. Anthill Pro uses log4j as a logging framework and Tomcat uses commons-logging. Commons-logging is a wrapper around the existing logging libraries as log4j, java.util.logging, etc. So we should first configure Tomcat logging and than Anthill Pro logging:
1. Add logging.properties file in $CATALINA_HOME/common/classes/logging.properties with the following contents. Note that this is a java.util.logging configuration:
handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4admin.org.apache.juli.FileHandler, 5host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.
2localhost.org.apache.juli.FileHandler.level = FINE
2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.
3manager.org.apache.juli.FileHandler.level = FINE
3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
3manager.org.apache.juli.FileHandler.prefix = manager.
4admin.org.apache.juli.FileHandler.level = FINE
4admin.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
4admin.org.apache.juli.FileHandler.prefix = admin.
java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter
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].[/admin].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/admin].handlers = 4admin.org.apache.juli.FileHandler
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/AnthillPro].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/AnthillPro].handlers = 5host-manager.org.apache.juli.FileHandler
2. Add log4.configuration file in $ANTHILLPRO_HOME/conf with the following contents. Note that this is log4 configuration:
log4j.rootLogger=INFO, file
log4j.logger.com.urbancode=INFO, file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logs/AnthillPro_log.txt
log4j.appender.file.MaxFileSize=2MB
log4j.appender.file.MaxBackupIndex=20
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%-4r %-5p %c %x - %m%n
This configuration specifies that the maximum size of the log file is 2 MB and it is located in $CATALINA_HOME/logs/AnthillPro_log.txt; if the log file becomes more than 2MB, it is moved to AnthillPro_log.txt.no_of_backup where no_of_backup is the number of the backup and a new log file is created; if the backup files become more than 20 the oldest one is deleted.
Regards,
Antoine
