RE: environment variables for hostname and context name
From: Chris Cheshire [mailto:cheshira...@gmail.com]
Subject: Re: environment variables for hostname and context name
The tomcat directory is available through the environment
somehow, and is accessed as ${catalina.home}.
The ${catalina.home} reference is to a system property, not an environment
variable - these are two entirely separate and distinct mechanisms.
What else is exposed this way?
Use System.getProperties() in a servlet to find out. Lambda Probe has a screen
that displays all of them.

Subject: environment variables for hostname and context name
From: cheshira...@gmail.com
To: users@tomcat.apache.org
I'm reconfiguring the logging for my tomcat installation (6.0.20) to
use logback (instead of log4j) for the server logging so I can split
out error messages on a per host basis. I see that catalina.home is
exposed as an environment var and usable in the logging configuration
file - what about the hostname and context name/path?
I would like to set up a config file such that I don't have to edit it
every time I add a new sandbox for a developer (host). I want the
errors split out per host instead of one big file, because it makes it
possible to tell which sandbox had a problem with a JSP page for
instance.
I have it working if I hardcode a new appender per host going to a
separate file - something like :
root level=INFO
appender-ref ref=tomcat /
/root
logger
name=org.apache.catalina.core.ContainerBase.[Catalina].[a.domain.com]
level=INFO
additivity=false
appender-ref ref=tomcat_www /
/logger
and then two appenders, one for base logging from the tomcat
container, and then one for the host a.domain.com.
appender name=tomcat_www
class=ch.qos.logback.core.rolling.RollingFileAppender
File${catalina.home}/logs/tomcat-www.log/File
RollingPolicy class=ch.qos.logback.core.rolling.TimeBasedRollingPolicy

layout class=ch.qos.logback.classic.PatternLayout
Pattern%-25(%date{HH:mm:ss.SSS} [%thread])
%-5level%n%logger%n%msg%n/Pattern
/layout
/appender
Now when I log an error I see something like :
17:04:01.890 [http-8080-1] ERROR
org.apache.catalina.core.ContainerBase.[Catalina].[a.domain.com].[/foo].[default]

[jasper.jar:na]
[blah blah blah]
a.domain.com is the host where the web app is deployed. foo is the
context path under which the app is deployed. So if it was able to log
this information, it must be accessible somewhere, right? If I can get
access to the hostname and context name I can specify a dynamic file
name using these variables, and then only have one appender defined no
matter how many new hosts I deploy.

Re: environment variables for hostname and context name
I forced that error specifically for this example. That's not the issue. That is an example of what I am trying to log, and it illustrates that the information I need is available at the logging level.

In configuration files Log4J only support two kinds of variables:

Both ways do not have the ability to react on context information during
logging.

Re: environment variables for hostname and context name
Right. The tomcat directory is available through the environment
somehow, and is accessed as ${catalina.home}. From here I can get to
the tomcat logs directory. What else is exposed this way? I am hoping
that if the host and context are available in the logging message
itself, then maybe they are/can be exposed. Those values are generated
internally by tomcat when it dumps that stack trace, they weren't part
of the original logging message.

Re: Environment Variables
Tomcat does not use CLASSPATH. The list of variables used by tomcat is written at the top of catalina.sh script.
