The primary symptom will be unrotated monitor log files. Other symptoms include: - Error messages: -- error: /etc/monitors/monitors_logrotate.conf:6 unknown unit 'B' -- error: found error in /var/log/monitors/*.log , skipping - No disk space


Monitor logs will not consider file size for rotation criteria. An email notification is generated periodically, which references an error in /etc/monitors/monitors_logrotate.conf.


This occurs in /etc/monitors/monitors_logrotate.conf.


edit /etc/monitors/monitors_logrotate.conf to be "size=5M" instead of "size=5MB" the file should look like this once edited: /var/log/monitors/*.log { compress missingok notifempty rotate 7 size=5M olddir=/var/log/monitors }

Fix Information

Monitor log rotation functionality has been restored, so that emails with error statements sent to the postmaster every 30 minutes have been stopped.
