Managing logs

Nextcloud snap logs

In the event of an issue the Nextcloud logs could help figure out a probable cause. Most activities and actions in Nextcloud are logged. An automated log rotation mechanism within Nextcloud clears and retains the logs regularly to prevent an overflow.

Tip:

Apps for viewing logs: less is more, from head to tail with cat or bat but lnav is the way to go!

sudo lnav /var/snap/nextcloud/current/logs/nextcloud.log
