More often than not I run into applications that do not know how to clean up after themselves or their log files. On a couple of my boxes, there are applications that have two years of logs squirreled away, just taking up space. Since the application owners do not seem to care about these logs, and do not seem to have any intention of removing any of these logs, I decided to try rotatelog which I used at my old job.
One of the nice things about rotatelog is its config file. A sample file is shown below. After running "make install" all I needed to do was edit a few paths in the rotatelog script.
# File Trigger Owner:Group Mode Compress Archive_Limit
/var/log/wtmp 1M root:wheel 664 none 4
/var/log/wtmpx 4M root:wheel 644 none 4
/var/log/messages 74K root:wheel 664 Z 5
/var/log/maillog 60K root:wheel 664 gz 7
# Shell Command :file1,file2,file3 ... fileN
rotate1 : /var/log/wtmp,/var/log/wtmpx
kill -HUP `cat /var/run/syslog.pid` : /var/log/messages,/var/log/maillog
# Person to email rotation notification
Rotatelog installed itself to /usr/local/sbin/rotatelog, and created its config file to /usr/local/etc.
After giving it a test, I then I added it to crontab, and let it rip.
