Question

I only would like to keep the Access Logs of the last n days created by Tomcat Access Log Valve. http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access%20Log%20Val

Answer 1

For Tomcat 7 you can config tomcat/conf/logging.properties. Example:

1catalina.org.apache.juli.FileHandler.maxDays = 90

Note: that 1 is not a typo.

Answer 2

Incase of Apache Tomcat 7.0. You can use maxDays parameter to delete old log files. https://tomcat.apache.org/tomcat-7.0-doc/config/valve.html

Answer 3

For Windows, based on Erwan's answer in Tomcat localhost_access_log files cleanup, for the given folder and recursing into all subfolders:

forfiles /p "C:\path\to\httplogs\" /s /m *.log /d -10 /c "cmd /c del @PATH"

To test, just use:

forfiles /p "C:\path\to\httplogs\" /s /m *.log /d -10 /c "cmd /c dir /b @PATH"

And when having multiple suffixes in the log folder, like both .txt and .log, see using FORFILES in batch to delete tmp and bak files older than a week:

for %%t in (.txt, .log) do forfiles /p "C:\path\to\httplogs\" /s /m *%%t /d -10 /c "cmd /c del @PATH"

Answer 4

By default rotatable is true for Access Log, so you will be having a new file created every 24 hours.

Tomcat itself does not do any housekeeping on the old files, the general principle on a Unix system is to have a cron job set up on the system to archive older files into a back up directory and/or delete them.

Answer 5

You can try to create logrotate config:

#cat /etc/logrotate.d/tomcat
/var/log/tomcat/*.log {
        su tomcat tomcat
        copytruncate  
        daily  
        rotate 6  
        compress  
        missingok
}

"su tomcat tomcat" - i added for avoiding logrotate error on wrong permissions

Answer 6

run in terminal:

locate RELEASE-NOTES | egrep 'tomcat|apache' | xargs grep "Apache Tomcat Version"
