I recently had a 100% utilization on my nextcloud server 14.0.3 (not sure what happened) but would like to know if there are any tools I can use in order to send me an email notifying me of the high utilization of the server cpu?
im not very familiar with Nagios and not sure if its free for personal use.
For the time being Webmin can help me a bit more even to keep the server updated with email notifications.
