# Activity app

You can configure your Nextcloud server to automatically send out e-mail notifications to your users for various events like:

- A file or folder has been shared

- A new file or folder has been created

- A file or folder has been changed

- A file or folder has been deleted

Users can see actions (delete, add, modify) that happen to files they have access to. Sharing actions are only visible to the sharer and sharee.

## Enabling the activity app

The Activity App is shipped and enabled by default. If it is not enabled simply go to your Nextcloud Apps page to enable it.

## Configuring your Nextcloud for the activity app

To configure your Nextcloud to send out e-mail notifications a working Email is mandatory.

Furthermore it is recommended to configure the background job `Webcron` or `Cron` as described in Background jobs.

There is also a configuration option `activity_expire_days` available in your `config.php` (See Activity app) which allows you to clean-up older activities from the database.

## Activities in groupfolders

By default activities in groupfolders are only generated for the current user. This is due to the logic of groupfolders. There is a config flag `activity_use_cached_mountpoints` that makes activities in groupfolders work like in normal shares when set to `true`.

Warning

This config option comes with the following limitations:

1. Users that had access to a groupfolder, share or external storage can see activities in their stream and emails that happen after they are removed until they login again

2. Users that are newly added to a groupfolder, share or external storage can not see activities in their stream nor emails that happen after they are added until they login again

## Better scheduling of activity emails

In certain scenarios it makes sense to send the activity emails out more regularly, e.g. you want to send the hourly emails always at the full hour, daily emails before people start to work in the morning and weekly mails shall be send on monday morning, so people can read up when starting into the week.

A console command is available to trigger sending those emails. This allows to set up special cron jobs on your server with the known granularity, instead of relying on the Nextcloud cron feature which is not very flexible on scheduling.

To implement the samples mentioned above, the following three entries are necessary:

    # crontab -u www-data -e
     0  *  *  *  *    php -f /var/www/nextcloud/occ activity:send-mails hourly
    30  7  *  *  *    php -f /var/www/nextcloud/occ activity:send-mails daily
    30  7  *  *  MON  php -f /var/www/nextcloud/occ activity:send-mails weekly

If you want to manually send out all activity emails which are queued, you can run `occ activity:send-mails` without any argument.
