The details about a composite alarm.

Contents

ActionsEnabled

Indicates whether actions should be executed during any changes to the alarm state.

Type: Boolean

Required: No

ActionsSuppressedBy

When the value is ALARM, it means that the actions are suppressed because the suppressor alarm is in ALARM When the value is WaitPeriod, it means that the actions are suppressed because the composite alarm is waiting for the suppressor alarm to go into into the ALARM state. The maximum waiting time is as specified in ActionsSuppressorWaitPeriod. After this time, the composite alarm performs its actions. When the value is ExtensionPeriod, it means that the actions are suppressed because the composite alarm is waiting after the suppressor alarm went out of the ALARM state. The maximum waiting time is as specified in ActionsSuppressorExtensionPeriod. After this time, the composite alarm performs its actions.

Type: String

Valid Values: WaitPeriod | ExtensionPeriod | Alarm

Required: No

ActionsSuppressedReason

Captures the reason for action suppression.

Type: String

Length Constraints: Minimum length of 0. Maximum length of 1024.

Required: No

ActionsSuppressor

Actions will be suppressed if the suppressor alarm is in the ALARM state. ActionsSuppressor can be an AlarmName or an Amazon Resource Name (ARN) from an existing alarm.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1600.

Required: No

ActionsSuppressorExtensionPeriod

Important

ExtensionPeriod is required only when ActionsSuppressor is specified.

Type: Integer

Required: No

ActionsSuppressorWaitPeriod

The maximum time in seconds that the composite alarm waits for the suppressor alarm to go into the ALARM state. After this time, the composite alarm performs its actions.

Important

WaitPeriod is required only when ActionsSuppressor is specified.

Type: Integer

Required: No
