logrotate: delete tomcat/jboss logs older than n days

If you don't want to use find inside postrotate, no, you can't.

logrotate treats every instance of server.log rotated by Tomcat/JBoss as a different file, and since they are unique, logrotate will rotate them only once. maxage - the directive that removes rotated logs older than n days - is only checked if the logfile is to be rotated, so that maxage is only executed once and can't keep track of the file's age.

However, if you change your mind about using find, logrotate can help you simplify the management of log files created by Tomcat and JBoss. I use it to compress and remove old files with a configuration file like this:

/path/to/logs/server.log.????-??-?? {
    compress
    compresscmd /usr/bin/bzip2
    nocreate
    nodateext
    ifempty
    missingok
    rotate 1
    size 0
    start 0
    lastaction
        # Remove rotated files older than 180 days
        find /path/to/logs -name 'server.log.????-??-??.0.bz2' -mtime +180 -exec rm {} \;
    endscript
}

where:

• rotate 1 and compress rename and compress, say, server.log.20131201 to server.log.20131201.0.bz2. The 0 between the timestamp and the .bz2 extension comes from start 0.
• size 0 makes sure that files are always renamed and compressed.
• The lastaction block removes rotated files older than 180 days.
