Check nextcloud-stats

Overview

This plugin lets you track the number of active users over time, the number of shares in various categories and some storage statistics against a Nextcloud server. Might take up to 30 seconds for the first time; after that, still takes a few seconds.

To access the serverinfo API you will need the credentials of an admin user. It is recommended to create an app password (at https://cloud.example.com/index.php/settings/user/security) or a separate user for that purpose.

Hints:

  • If you simply want to check the availability of the Nextcloud web frontend, you have to use other checks.

  • If a Nextcloud App leads to a „500 Internal Server Error“, the Nextcloud API often still remains intact (so this check can’t report this).

Tested with Nextcloud 15+.

Troubleshooting

Unknown error while fetching http://localhost/nextcloud/ocs/v2.php/apps/serverinfo/api/v1/info?format=json, maybe timeout or error on webserver

Check the Nextcloud API endpoint URL. Maybe change from http(s)://localhost to http(s)://127.0.0.1.

HTTP error „401 Unauthorized“ while fetching http://…

Password is correct? Maybe you enabled 2FA. Use an app password for your monitoring server.
