Re: Apache Tomcat 7, Logrotate

[Web2 Solutions]

Hallo David, David N. Smith 25 Oct 2013 13:42 I think here is where you get confused. The "original (empty) file" is not the original file. It is a new file that happens to have the same name as the the one that was renamed. The true original file is the one that was renamed and tomcat continues to use it completely unaware of your rename. thx, I got that now. Configuring your apps to use a true logging system and configuring the log system to rotate is the best option. Barring that, it get's tricky. You might be able to get away with copying the log file to another and then truncating the original but I think that only really works on *nix based systems. Windows if memory serves will pad the truncated file with empty space and append right were it left off. I'm on linux and I would test the moving renamed file to a new folder. How comes Tomcat does not have a layer for logrotate for this?! There has been discussion on the list in the past about this if your interested in doing some searching. Ok, I'll make a search. --David Thx, Michael --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org Konstantin Kolinko 25 Oct 2013 11:54 2013/10/25 Web2 Solutions <m...@web2-solutions.com>: Hallo All, I've installed tomcat 7.0.42 and due heavy use my catalina.out and localhost_access-jjj-mm-dd.txt grows quit big. I've successfully configured logrotate to rotate both files. I've removed the date from the access log. So Tomcat now writes without rotating into localhost_access.txt Logrotate now create a new file (localhost_access-dd-mm-dd.txt) and makes localhost_access.txt empty. But tomcat now writes into the new localhost_access-dd-mm-dd.txt instead of the configured file (localhost_access.txt). FYI: You can configure the filename pattern so that it rotates more frequently, e.g. every hour or every ten minutes. What do I have todo so that tomcat continues to write into localhost_access.txt even after rotating? Renaming the file is futile, because Tomcat (for access logs) or the shell (for catalina.out) has the file open and continues to write to it, regardless of the file name. You can use copytruncate option of logrotate. FYI: catalina.out is not a proper log file, but a redirection of stdout (as managed in catalina.sh script that launches Tomcat java process). If a system is configured properly, this file is usually empty.
