Class PutCompositeAlarmRequest

    • Method Detail

      • actionsEnabled

        public final Boolean actionsEnabled()

        Indicates whether actions should be executed during any changes to the alarm state of the composite alarm. The default is TRUE.

        Returns:
        Indicates whether actions should be executed during any changes to the alarm state of the composite alarm. The default is TRUE.

      • hasAlarmActions

        public final boolean hasAlarmActions()
        For responses, this returns true if the service returned a value for the AlarmActions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • alarmActions

        public final List<String> alarmActions()

        The actions to execute when this alarm transitions to the ALARM state from any other state. Each action is specified as an Amazon Resource Name (ARN).

        Valid Values: arn:aws:sns:region:account-id:sns-topic-name | arn:aws:ssm:region:account-id:opsitem:severity

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasAlarmActions() method.

        Returns:
        The actions to execute when this alarm transitions to the ALARM state from any other state. Each action is specified as an Amazon Resource Name (ARN).

        Valid Values: arn:aws:sns:region:account-id:sns-topic-name | arn:aws:ssm:region:account-id:opsitem:severity

      • alarmDescription

        public final String alarmDescription()

        The description for the composite alarm.

        Returns:
        The description for the composite alarm.

      • alarmName

        public final String alarmName()

        The name for the composite alarm. This name must be unique within the Region.

        Returns:
        The name for the composite alarm. This name must be unique within the Region.

      • alarmRule

        public final String alarmRule()

        An expression that specifies which other alarms are to be evaluated to determine this composite alarm's state. For each alarm that you reference, you designate a function that specifies whether that alarm needs to be in ALARM state, OK state, or INSUFFICIENT_DATA state. You can use operators (AND, OR and NOT) to combine multiple functions in a single expression. You can use parenthesis to logically group the functions in your expression.

        You can use either alarm names or ARNs to reference the other alarms that are to be evaluated.

        Functions can include the following:

        • ALARM("alarm-name or alarm-ARN") is TRUE if the named alarm is in ALARM state.

        • OK("alarm-name or alarm-ARN") is TRUE if the named alarm is in OK state.

        • INSUFFICIENT_DATA("alarm-name or alarm-ARN") is TRUE if the named alarm is in INSUFFICIENT_DATA state.

        • TRUE always evaluates to TRUE.

        • FALSE always evaluates to FALSE.

        TRUE and FALSE are useful for testing a complex AlarmRule structure, and for testing your alarm actions.

        Alarm names specified in AlarmRule can be surrounded with double-quotes ("), but do not have to be.

        The following are some examples of AlarmRule:

        • ALARM(CPUUtilizationTooHigh) AND ALARM(DiskReadOpsTooHigh) specifies that the composite alarm goes into ALARM state only if both CPUUtilizationTooHigh and DiskReadOpsTooHigh alarms are in ALARM state.

        • ALARM(CPUUtilizationTooHigh) AND NOT ALARM(DeploymentInProgress) specifies that the alarm goes to ALARM state if CPUUtilizationTooHigh is in ALARM state and DeploymentInProgress is not in ALARM state. This example reduces alarm noise during a known deployment window.

        • (ALARM(CPUUtilizationTooHigh) OR ALARM(DiskReadOpsTooHigh)) AND OK(NetworkOutTooHigh) goes into ALARM state if CPUUtilizationTooHigh OR DiskReadOpsTooHigh is in ALARM state, and if NetworkOutTooHigh is in OK state. This provides another example of using a composite alarm to prevent noise. This rule ensures that you are not notified with an alarm action on high CPU or disk usage if a known network problem is also occurring.

        The AlarmRule can specify as many as 100 "children" alarms. The AlarmRule expression can have as many as 500 elements. Elements are child alarms, TRUE or FALSE statements, and parentheses.

        Returns:

For each alarm that you reference, you designate a function that specifies whether that alarm needs to be in ALARM state, OK state, or INSUFFICIENT_DATA state.

        • INSUFFICIENT_DATA("alarm-name or alarm-ARN") is TRUE if the named alarm is in INSUFFICIENT_DATA state.

        • TRUE always evaluates to TRUE.

        • FALSE always evaluates to FALSE.

      • hasInsufficientDataActions

        public final boolean hasInsufficientDataActions()
        For responses, this returns true if the service returned a value for the InsufficientDataActions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • insufficientDataActions

        public final List<String> insufficientDataActions()

        public final boolean hasOkActions()
        For responses, this returns true if the service returned a value for the OKActions property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property).

      • hasTags

        public final boolean hasTags()
        For responses, this returns true if the service returned a value for the Tags property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

      • tags

        public final List<Tag> tags()

        A list of key-value pairs to associate with the composite alarm. You can associate as many as 50 tags with an alarm.

        Tags can help you organize and categorize your resources. You can also use them to scope user permissions, by granting a user permission to access or change only resources with certain tag values.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTags() method.

        Returns:

        Returns:
        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.
