eucalyptus-nc-logrotate

Alternative Log Rotation Setup for eucalyptus-nc process using cron and logrotate.

Installation

On the machine that is running the eucalyptus-nc process, install the following files:

• place nc-log-rotate.sh in the /usr/share/eucalyptus/ directory
• place euca-nc in the /etc/logrotate.d/ directory
• edit cron (i.e. crontab -e) to run nc-log-rotate.sh every five minutes:

*/5 * * * * /bin/bash /usr/share/eucalyptus/nc-log-rotate.sh

• To make the new cronjob is loaded, restart crond (i.e. service crond restart)

By default, the rotation will occur with the /var/log/eucalyptus/nc.log file is greater than or equal to 29 M. Upon rotation, it zeros out /var/log/eucalyptus/nc.log file. This is done to keep the embedded Eucalyptus log rotation process from being kicked off when the file hits 32 M.
