Configuration

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
}
