Application logging settings

The upstart log settings on a fresh Ubuntu 14.04 are pretty lax, daily log rotation and the log files are kept for a week only. Something you probably do not want to have for a production app.

To change that you need to edit /etc/logrotate.d/upstart. I use this config to rotate them weekly, keep logfiles under 20MB and keep them for about a year (given they do not execeed the size limit of 20MB too often, which also triggers log rotation).

/var/log/upstart/*.log {
        weekly
        size 20M
        missingok
        rotate 52
        notifempty
        nocreate
}
