Subject RE: Log rotation HOWTO
Date Tue, 29 Jun 2004 21:33:43 GMT
Oh, no....SYNTAX ERROR..sorry
 
WRONG: 
0 1 * * * /path/to/script/rotate_log >> /path/to/script/rotate_log 2>&1
 
I forgot to name the log file (otherwise you overwrite your rotate_log
script, and it will only work once):
RIGHT:
0 1 * * * /path/to/script/rotate_log >> /path/to/script/logfile 2>&1
 
Anyway...a good example of how you not should name your files..

Hi, maybe you would try the following:

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 shared by all Contexts related to this virtual host. By

default (when using FileLogger), log files are created in the "logs"

directory relative to $CATALINA_HOME. If you wish, you can specify

a different directory with the "directory" attribute. Specify either a

relative (to $CATALINA_HOME) or absolute path to the desired

directory.-->

<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
