How to split the default stdout log?
Hello everyone,
I am using Tomcat 5.5.28 in Windows systems. Because there are lots of codes
like "System.out.println(" some info here")" in the apps, after a few days
the file "stdout_*.log" in the "/logs" folder becomes so large that we
cannot open it. Due to some reasons, I cannot modify the codes, so the only
solution is to make the log generated everyday.
I have tried the log4j, but I cannot redirect the stand output to the log
files. Only there log infos that send out by logging class can be recorded
in the logs generated by log4j.
Anyone know a simple solution to meet my needs?

My Environment:
Using CATALINA_BASE: D:\tomcat5528
Using CATALINA_HOME: D:\tomcat5528
Using CATALINA_TMPDIR: D:\tomcat5528\temp
Using JRE_HOME: D:\java\jdk1.5.0_12
Using CLASSPATH: D:\tomcat5528\bin\bootstrap.jar
Server version: Apache Tomcat/5.5.28
Server built: Jul 24 2009 01:33:09
Server number: 5.5.28.0
OS Name: Windows Vista
OS Version: 6.1
Architecture: x86
JVM Version: 1.5.0_12-b04
JVM Vendor: Sun Microsystems Inc.
I have used the tomcat unzipped from the zip file, and added it in the
system service using "service.bat install".
The default setting of the stdout in the Logging tabpage is : auto, at this
situation, when tomcat runs, it will generate log file in
"D:\tomcat5528\log" folder, and the related log file name will be
"stdout_20100707.log".
If I set that box to a fixed file, such as "tomcat.log", then if tomcat
restarts, it will generate a file called "tomcat.log". Before the next
restart (maybe many months), all the output info are appended to that file,
which makes the log file to large.

Hi again.
I tried what I suggested earlier (with the Apache rotatelogs utility), but that does not
seem to work. (*)
Can you confirm :
1) that you are running Tomcat 5.5 as a Windows Service
2) if yes, what you currently see when you run the tomcat5w.exe GUI, in the Logging tab,
in the boxes for STDOUT and STDERR
3) what name do your logfiles have ?
Thanks
(*) When i do that, I get a logfile tomcat_dir/logs/jakarta_service_20100706.log
containing 2 lines :
[2010-07-06 16:12:50] [591 javajni.c] [error] Could not create instance of
java/io/FileOutputStream
[2010-07-06 16:12:50] [591 javajni.c] [error] Could not create instance of
java/io/FileOutputStream
from which i suspect that the tomcat5.exe/procrun wrapper does not like it, when one tries
to give it something like this as a destination for its logfiles :
|c:/tomcat5.5/bin/rotatelogs.exe -l C:/Tomcat5.5/logs/stdout.%Y.%m.%d 86400
(I also tried flipping the slashes the other way, with no more success).

Read what I posted - use swallowOutput to capture the writes to System.out.

Thanks.
The bad news is all the output codes are in a single webapp, and have no
hope to use log4j instead of the current "system.out" codes.
Just I hope to find a way that can make tomcat generate a stdout.log file
eveyday, or at any interval.

Not sure there's going to be any ready way for Tomcat to fix sloppy webapp programming, but start with setting swallowOutput to true in the <Context> of interest (or in the global one). This will divert stdout and stderr for each webapp to the webapp's logger. You can then use log4j in the webapp, and make use of its built-in rotation capabilities.
Look here for the doc:

I don't know, and I did not find anything to that effect in the Tomcat or Daemon
documentation.
But you could try the following :
In the Apache httpd distribution, there is a program called "rotatelogs.exe".
Its documentation is here : http://httpd.apache.org/docs/2.2/programs/rotatelogs.html
You could try to download Apache, extract this program, add it to the tomcat/bin
directory, and then in tomcat5w.exe try to set the filename to something like :
|D:/Tomcat 5.5/bin/rotatelogs.exe -l D:/Tomcat 5.5/logs/stdout.%Y.%m.%d 86400
I have never tried this, and I don't know if it works.
If it does, then let us know, because it might be handy for others.
Note : I know that this is not the default in the Tomcat installation, but I always
recommend to install programs in directory paths *without embedded spaces* (e.g.
"D:/tomcat5.5" instead of "D:/tomcat 5.5". One of the reasons is shown above : does one
need to quote this path or not, and if yes how ?

Thanks Andre!
But when tomcat5 starts, it will generate a file like stdout_yyyymmdd.log,
but when it runs for a couple of days, there will be only one file, and all
the infos are appended to that file. What I want is that tomcat can
automatic generate multiple files such as one file one day so that the
single log file will not be so large.
Like in log4j, I can set the parameter like
"log4j.appender.R=org.apache.log4j.DailyRollingFileAppender" so that
everyday it will generate a new file.
in the "logging" tab page, I can only redirect the stdout to a single file.
Does it support parameters like "D:\Tomcat 5.5\logs\{%date%}.log"?

Hi.
You do not say, but I presume that you are running Tomcat 5.5 as a Windows Service.
If so, then Tomcat (or rather the JVM which runs Tomcat), is running inside of a "wrapper"
program called "tomcat5.exe" (tomcat_dir/bin/tomcat5.exe).
This program "catches" the stdout/stderr of the JVM, and redirects them to files.
To which files it redirects them, is stored in the Windows Registry.
When tomcat5.exe starts, it reads a series of parameters from the Registry, and then
starts the JVM (and Tomcat) using these parameters.
There is another program in tomcat_dir/bin, called "tomcat5w.exe".
This is a GUI which enables you to change these Registry parameters used by tomcat5.exe.
Double-click on the tomcat5w.exe program, and navigate to the "Logging" tab.
Maybe this gives you an idea.
For a complete explanation, start here : http://commons.apache.org/daemon/
tomcat5.exe is really a renamed prunsrv
tomcat5w.exe is really a renamed prunmgr
