#### New templates

The following templates are now available for out-of-the-box monitoring:

    templates;

You can get these templates:

-   In *Configuration* → *Templates* in new installations;

    templates from Zabbix [Git

    or find them in the `templates` directory of the downloaded latest
    Zabbix version. Then, while in *Configuration* → *Templates* you can
    import them manually into Zabbix.
