Re: Log rotation HOWTO

I thought that would be an easier way, just as you can do using a diferent class appender with log4j.

Create a bash-script (or on windows a .bat, with modifications)
create a file called e.g. /path/to/script/rotate_log
#!/bin/sh
file_to_zip=`date +'%m%d'
cp /your_path_to/catalina.out /your_rot_dir/$file_to_zip
echo -n "" > catalina.out
cd /your_rot_dir
gzip $file_to_zip
cd /your_path_to
$ crontab -e (as a user with reading permission for catalina.log and add the
following line to rotate the log 1 am every day)
0 1 * * * /path/to/script/rotate_log >> /path/to/script/rotate_log 2>&1
If you are very unlucky, you might loose log entrys between the cp statement
and the echo statement.
At least this doesn't change the i-node of the catalina.out file, hence the
logging should continue.
I have not tried this myself, and there is NO WARRENTY that it is working.
I SUGGEST you await some comments from other users here before you trie it
out.
Be aware of possible misspellings of file names. It is ment to give you an
idea of how to rotate the logs.

Hi,
Or rather, you can't rotate catalina.out using functionality built into
tomcat. You can use an external tool such as Apache's logrotate (no space in
the name, google for it). And as the original poster mentioned this has been
discussed numerous times ;)

You can't rotate catalina.out. You shouldnt have much in there anyway if
your webapps are coded correctly. If you have an webapp that outputs a lot
to it you can add a customer logger to the context and it is rotated
automatically every day.

I didn't find how to make the catalina.log file split each day.

<Logger className="org.apache.catalina.logger.FileLogger"
directory="logs" prefix="localhost_log." suffix=".txt"
timestamp="true"/>
what should I change in the following tag to get it done...?
thanks

I haven't been able to find a clear answer to this anywhere online,
hopefully you fine folks can help...
I need a way to rotate my stdout log in Tomcat 5.0.18. It could be dalily
or weekly (monthly might be OK too).
Is thre any way to do this? I assume so, so how? Thanks in advance all!

Could you please use tomcats web admin to change logging settings...
By default you can access http://localhost:8080/admin
You can activate a separate log for several contents.

Betreff: Managing Tomcat logs
Hi,
I am using Tomcat as web server for my application. I start Tomcat using
windows service. All the logs generated by the Application are written in
to
a file called stdout.log which is under tomca/logs folder.
I have noticed that with continuous use of application,stdout file size
increasing to a large extent. To delete the it I have to stop the tomcat.
Is there any way that I can manage the logs date wise
automatically(without
manual intervention). I am not using any third party tool for logging.
The logging mechanism I use is very simple.
We have class Debug.java that have a method log(String); This log() method
use System.out.println(); In the application, I use
Debug.log("Exception");
I will be more happy if there is any way to manage logs.
I have also noticed the following logs generated by Tomcat:
1.localhost_log.2004-06-18.txt
2.localhost_access_log.2004_06_22.txt
How to maintain these logs?. Can we off them permanently?
Thanks in advance.

Instead of using System.out.println() to log your messages, use the
HttpServlet's log() method. You can specify the logging class you want to
use,
the path it writes to, the base name, and extension. Each day a new file
is
created and you can simply delete the old ones as they are closed when a
new
file is started each day. You could also create your own logger that
manages
the
file size in some way. I have used the former and have specified the file
name
and path so that it easy form me to manage. My logs are separate from the
normal
logs as well.

You could add a customer Logger tag to the context in your server.xml and
add the swallowOutput="true" attribute, this will put standard out and
standard error into the log file that you specify which is rotated on a
daily basis automatically for you by tomcat.
