IBM::EC2::Alarm

This resource type represents an alarm on Amazon Elastic Compute Cloud. It extends the type OS::Ceilometer::Alarm.

The blueprint uses the core properties and extended properties, if any, from this resource type. Review and configure the applicable heat resources that apply to your configuration information.

In the blueprint designer, you can configure the properties that the following table includes. Properties are listed as either core or extended. Each type of property is located in separate sections of the heat resource that you can view in the blueprint designer. You set the core properties in the properties section and set the extended properties in the metadata section of the blueprint.

Table 1. Properties
Name	Type	Required	Core or extended	Description

description	String	False	Core	Description for the alarm.
enabled	Boolean	False	Core	True if alarm evaluation and actions are enabled. By default, the enabled parameter is set to `True`.
evaluation_periods	Integer	False	Core	Number of periods to evaluate over.
insufficient_data_actions	List	False	Core	A list of URLs to invoke when the state makes the transition to `insufficient-data`.
matching_metadata	Map	False	Core	In addition to the meter name, the meter must match this resource metadata (key=value).
meter_name	String	True	Core	Meter name that is watched by the alarm.
name	String	False	Core	Name of alarm.
ok_actions	List	False	Core	A list of URLs to invoke when state makes the transition to `OK`.
period	Integer	False	Core	Period to evaluate over, in seconds.
repeat_actions	Boolean	True	Core	Set the repeat_actions parameter to `False` to trigger actions when the threshold is reached and the alarm's state has changed. By default, actions are called each time that the threshold is reached.
