 -   `chart`    : Chart ids/names, as shown on the dashboard. These will match the `on` entry of a configured `alarm`.
 -   `context`  : Chart context, as shown on the dashboard. These will match the `on` entry of a configured `template`.
 -   `hosts`    : The hostnames that will need to match.
--   `families` : The alert families.
 
 You can add any of the selection criteria you need on the request, to ensure that only the alerts you are interested in are matched and disabled/silenced. e.g. there is no reason to add `hosts: *`, if you want the criteria to be applied to alerts for all hosts.
