Help with Log Level in Tomcat 6 Logging
Hello,
Im a newbie to Tomcat logging.
Here is the logging.properties of my Catalina installation:
---
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 = ${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.
4host-manager.org.apache.juli.FileHandler.level = FINE
4host-manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
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
The problem I have is that in my daily rolling catalina-[data].out I only
get SEVERE level messages.
Given the above configuration, my understanding from reading this (
http://tomcat.apache.org/tomcat-6.0-doc/logging.html) is that FINE for the
FileHandler would log everything above ie. FINE,CONFIG,INFO,WARNINGBut
Im only getting SEVERE written to my daily rolling logfile.
Im not sure how to change this behaviour even after reading through -
http://tomcat.apache.org/tomcat-6.0-doc/logging.html -
and any advice is appreciated.
Thanks
Jon

If it may contribute to less confusion : for as long as I remember, and still in tomcat 6.0.26 e.g., the comment in front of this paragraph at the end of the logging.properties file # 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 has had a comment totally out of sync with the lines that follow. Unfortunately, I do not know how to rectify it, because Tomcat logging has long been a mysterious area where I fear to walk alone even by day. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
