Alarm

Gets and sets the property Arn.

The Amazon Resource Name (ARN) of the alarm.

Gets and sets the property ComparisonOperator.

The arithmetic operation used when comparing the specified statistic and threshold.

Gets and sets the property ContactProtocols.

The contact protocols for the alarm, such as Email, SMS (text messaging), or both.

Gets and sets the property CreatedAt.

The timestamp when the alarm was created.

Gets and sets the property DatapointsToAlarm.

The number of data points that must not within the specified threshold to trigger the alarm.

Gets and sets the property EvaluationPeriods.

The number of periods over which data is compared to the specified threshold.

Gets and sets the property Location.

An object that lists information about the location of the alarm.

Gets and sets the property MetricName.

The name of the metric associated with the alarm.

Gets and sets the property MonitoredResourceInfo.

An object that lists information about the resource monitored by the alarm.

Gets and sets the property Name.

The name of the alarm.

Gets and sets the property NotificationEnabled.

Indicates whether the alarm is enabled.

Gets and sets the property NotificationTriggers.

The alarm states that trigger a notification.

Gets and sets the property Period.

The period, in seconds, over which the statistic is applied.

Gets and sets the property ResourceType.

The Lightsail resource type of the alarm.

Gets and sets the property State.

The current state of the alarm.

An alarm has the following possible states:

• ALARM - The metric is outside of the defined threshold.

• INSUFFICIENT_DATA - The alarm has just started, the metric is not available, or not enough data is available for the metric to determine the alarm state.

• OK - The metric is within the defined threshold.

Gets and sets the property Statistic.

The statistic for the metric associated with the alarm.

The following statistics are available:

• Minimum - The lowest value observed during the specified period. Use this value to determine low volumes of activity for your application.

• Maximum - The highest value observed during the specified period. Use this value to determine high volumes of activity for your application.

• Sum - All values submitted for the matching metric added together. You can use this statistic to determine the total volume of a metric.

• Average - The value of Sum / SampleCount during the specified period. By comparing this statistic with the Minimum and Maximum values, you can determine the full scope of a metric and how close the average use is to the Minimum and Maximum values. This comparison helps you to know when to increase or decrease your resources.

• SampleCount - The count, or number, of data points used for the statistical calculation.

Gets and sets the property SupportCode.

The support code. Include this code in your email to support when you have questions about your Lightsail alarm. This code enables our support team to look up your Lightsail information more easily.

Gets and sets the property Threshold.

The value against which the specified statistic is compared.

Gets and sets the property TreatMissingData.

Specifies how the alarm handles missing data points.

An alarm can treat missing data in the following ways:

• breaching - Assume the missing data is not within the threshold. Missing data counts towards the number of times the metric is not within the threshold.

• notBreaching - Assume the missing data is within the threshold. Missing data does not count towards the number of times the metric is not within the threshold.

• ignore - Ignore the missing data. Maintains the current alarm state.

• missing - Missing data is treated as missing.

Gets and sets the property Unit.

The unit of the metric associated with the alarm.
