Information
The system includes the capability of rotating log files regularly to avoid filling up the system with logs or making the logs unmanageably large. The file /etc/logrotate.d/syslog is the configuration file used to rotate log files created by syslog or rsyslog.
Note: If no maxage setting is set for logrotate a situation can occur where logrotate is interrupted and fails to delete rotated logfiles. It is recommended to set this to a value greater than the longest any log file should exist on your system to ensure that any such logfile is removed but standard rotation settings are not overridden.
Rationale:
By keeping the log files smaller and more manageable, a system administrator can easily archive these files to another system and spend less time looking through inordinately large log files.
Solution
Edit /etc/logrotate.conf and /etc/logrotate.d/* to ensure logs are rotated according to site policy.
