Comment: Add reference to BZ 53930 "allow capture of catalina stdout/stderr to a command instead of just a file"

...

  1. If you are using jsvc 1.0.4 or later (from Apache Commons Daemon project) to launch Tomcat, you can send SIGUSR1 signal to jsvc to get it to re-open its log files (Jira Ticket). You can couple this with 'logrotate' or your favorite log-rotation utility (including good-old 'mv') to re-name catalina.out at intervals and then get jsvc to re-open the original (catalina.out) file and continue writing to it.
  2. Use 'logrotate' with the 'copytruncate' option. This allows you to externally rotate catalina.out without changing anything within Tomcat.
  3. Modify bin/catalina.sh (or bin/catalina.bat) to pipe output from the JVM into a piped-logger such as chronolog or Apache httpd's rotatelogs (note that the previous reference is for Apache httpd documentation and *is not applicable to Tomcat* – it merely illustrates the concept).
    See also the patch in Bug 53930, "Allow capture of catalina stdout/stderr to a command instead of just a file".
