The admin can look up this information directly in Nextcloud (Settings -> Management-> Information) or connect an external monitoring tool to the provided end-points.

Installation

This app is part of the standard Nextcloud package and can be found in the directory nextcloud/apps/serverinfo

API

The API provides a lot of information about a running Nextcloud instance in XML or JSON format by using the following URL.

https://<nextcloud-fqdn>/ocs/v2.php/apps/serverinfo/api/v1/info

• To request the information in JSON append the url parameter format=json
• Use the url parameter skipUpdate=true to omit server updates.
• Use the url parameter skipApps=true to omit app updates (including available app updates will send an external request to the app store).

Configuration

Background job to update storage statistics

Since collecting storage statistics might take time and cause slow downs, they are updated in the background. A background job runs once every three hours to update the number of storages and files. The interval can be overridden per app settings (the value is specified in seconds):

php occ config:app:set --value=3600 serverinfo job_interval_storage_stats

It is also possible to trigger the update manually per occ call. With verbose mode enabled, the current values are being printed.

php occ serverinfo:update-storage-statistics -v --output=json_pretty
{
    "num_users": 80,
    "num_files": 3934,
    "num_storages": 2545,
    "num_storages_local": 2,
    "num_storages_home": 2510,
    "num_storages_other": 33
}

Restricted mode (>= Nextcloud 28)

To obtain information about your server, the serverinfo app reads files outside the application directory (e.g. /proc on Linux) or executes shell commands (e.g. df on Linux).

If you don't want that (for example, to avoid open_basedir warnings) enable the restricted mode.

Enable:

php occ config:app:set --value=yes serverinfo restricted_mode

Disable:

php occ config:app:delete serverinfo restricted_mode

Show phpinfo (>= Nextcloud 28)

Enable:

php occ config:app:set --value=yes serverinfo phpinfo

Disable:

php occ config:app:delete serverinfo phpinfo
