Source code in docs_src/capo_lightsail/types/alarm.py
arn
instance-attribute
¶
arn: NotRequired[NonEmptyString]
The Amazon Resource Name (ARN) of the alarm.
comparison_operator
instance-attribute
¶
comparison_operator: NotRequired[ComparisonOperator]
The arithmetic operation used when comparing the specified statistic and threshold.
contact_protocols
instance-attribute
¶
contact_protocols: NotRequired[ContactProtocolsList]
The contact protocols for the alarm, such as Email, SMS (text messaging), or both.
created_at
instance-attribute
¶
created_at: NotRequired[IsoDate]
The timestamp when the alarm was created.
datapoints_to_alarm
instance-attribute
¶
datapoints_to_alarm: NotRequired[integer]
The number of data points that must not within the specified threshold to trigger the alarm.
evaluation_periods
instance-attribute
¶
evaluation_periods: NotRequired[integer]
The number of periods over which data is compared to the specified threshold.
location
instance-attribute
¶
location: NotRequired[ResourceLocation]
An object that lists information about the location of the alarm.
metric_name
instance-attribute
¶
metric_name: NotRequired[MetricName]
The name of the metric associated with the alarm.
monitored_resource_info
instance-attribute
¶
monitored_resource_info: NotRequired[MonitoredResourceInfo]
An object that lists information about the resource monitored by the alarm.
notification_enabled
instance-attribute
¶
notification_enabled: NotRequired[boolean]
Indicates whether the alarm is enabled.
notification_triggers
instance-attribute
¶
notification_triggers: NotRequired[NotificationTriggerList]
The alarm states that trigger a notification.
period
instance-attribute
¶
period: NotRequired[MetricPeriod]
The period, in seconds, over which the statistic is applied.
resource_type
instance-attribute
¶
resource_type: NotRequired[ResourceType]
The Lightsail resource type of the alarm.
state
instance-attribute
¶
state: NotRequired[AlarmState]
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.
statistic
instance-attribute
¶
statistic: NotRequired[MetricStatistic]
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.
support_code
instance-attribute
¶
support_code: NotRequired[string]
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.
tags
instance-attribute
¶
tags: NotRequired[TagList]
The tag keys and optional values for the resource. For more information about tags in Lightsail, see the Amazon Lightsail Developer Guide.
threshold
instance-attribute
¶
threshold: NotRequired[double]
The value against which the specified statistic is compared.
treat_missing_data
instance-attribute
¶
treat_missing_data: NotRequired[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.
unit
instance-attribute
¶
unit: NotRequired[MetricUnit]
The unit of the metric associated with the alarm.
