A systems administrator is responsible for a Linux server that runs a custom application. The application writes logs to /var/log/app.log and rotates them using logrotate. Recently, the server ran out of disk space because log files were not being rotated. The administrator checks the logrotate configuration file /etc/logrotate.d/app and finds:
/var/log/app.log { weekly rotate 4 compress missingok notifempty
}
The administrator manually runs 'logrotate -f /etc/logrotate.d/app' and the log rotates successfully. However, the next day, the log is not rotated again. The administrator checks the cron job for logrotate and finds that /etc/cron.daily/logrotate exists and runs logrotate /etc/logrotate.conf. The administrator checks /etc/logrotate.conf and sees that it includes /etc/logrotate.d/*. What is the most likely reason the log is not rotating automatically?
