This is the first in a series of videos on how to manage and use LibreNMS. This is my first video, so please leave me comments if something is unclear or i could do something better.

To restart the LibreNMS Service use: systemctl restart librenms.service

Correction:
My first debug capture of the discovery and polling process didn't work because i had the error in the nginx config as shown at the end of the video. This should of still polled manually regardless of the librenms service status.
