 - `alert_channel_subscription` (Block List) An array of channel IDs and whether they're activated or not.

+- `degraded_response_time` (Number) The response time in milliseconds starting from which a check should be considered degraded. Possible values are between 0 and 5000. (Default `4000`).
 - `frequency_offset` (Number) To create a high frequency check, the property `frequency` must be `0` and `frequency_offset` can be `10`, `20` or `30`.
 - `group_id` (Number) The id of the check group this check is part of.
 - `group_order` (Number) The position of this check in a check group. It determines in what order checks are run when a group is triggered from the API or from CI/CD.
 - `locations` (Set of String) An array of one or more data center locations where to run the this check. (Default ["us-east-1"])
