alarms_list_only

Lists alarms in a region or regions, for all properties use alarms

Overview

Namealarms_list_only
TypeResource
DescriptionThe AWS::CloudWatch::Alarm type specifies an alarm and associates it with the specified metric or metric math expression.
When this operation creates an alarm, the alarm state is immediately set to INSUFFICIENT_DATA. The alarm is then evaluated and its state is set appropriately. Any actions associated with the new state are then executed.
When you update an existing alarm, its state is left unchanged, but the update completely overwrites the previous configuration of the alarm.

Fields

NameDatatypeDescription
threshold_metric_idstringIn an alarm based on an anomaly detection model, this is the ID of the ANOMALY_DETECTION_BAND function used as the threshold for the alarm.
evaluate_low_sample_count_percentilestringUsed only for alarms based on percentiles. If ignore, the alarm state does not change during periods with too few data points to be statistically significant. If evaluate or this parameter is not used, the alarm is always evaluated and possibly changes state no matter how many data points are available.
extended_statisticstringThe percentile statistic for the metric associated with the alarm. Specify a value between p0.0 and p100.
For an alarm based on a metric, you must specify either Statistic or ExtendedStatistic but not both.
For an alarm based on a math expression, you can't specify ExtendedStatistic. Instead, you use Metrics.
comparison_operatorstringThe arithmetic operation to use when comparing the specified statistic and threshold. The specified statistic value is used as the first operand.
treat_missing_datastringSets how this alarm is to handle missing data points. Valid values are breaching, notBreaching, ignore, and missing. For more information, see [Configuring How Alarms Treat Missing Data](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/AlarmThatSendsEmail.html#alarms-and-missing-data) in the *Amazon User Guide*.
If you omit this parameter, the default behavior of missing is used.
dimensionsarrayThe dimensions for the metric associated with the alarm. For an alarm based on a math expression, you can't specify Dimensions. Instead, you use Metrics.
periodintegerThe period, in seconds, over which the statistic is applied. This is required for an alarm based on a metric. Valid values are 10, 30, 60, and any multiple of 60.
For an alarm based on a math expression, you can't specify Period, and instead you use the Metrics parameter.
*Minimum:* 10
evaluation_periodsintegerThe number of periods over which data is compared to the specified threshold. If you are setting an alarm that requires that a number of consecutive data points be breaching to trigger the alarm, this value specifies that number. If you are setting an "M out of N" alarm, this value is the N, and DatapointsToAlarm is the M.
For more information, see [Evaluating an Alarm](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/AlarmThatSendsEmail.html#alarm-evaluation) in the *User Guide*.
unitstringThe unit of the metric associated with the alarm. Specify this only if you are creating an alarm based on a single metric. Do not specify this if you are specifying a Metrics array.
You can specify the following values: Seconds, Microseconds, Milliseconds, Bytes, Kilobytes, Megabytes, Gigabytes, Terabytes, Bits, Kilobits, Megabits, Gigabits, Terabits, Percent, Count, Bytes/Second, Kilobytes/Second, Megabytes/Second, Gigabytes/Second, Terabytes/Second, Bits/Second, Kilobits/Second, Megabits/Second, Gigabits/Second, Terabits/Second, Count/Second, or None.
namespacestringThe namespace of the metric associated with the alarm. This is required for an alarm based on a metric. For an alarm based on a math expression, you can't specify Namespace and you use Metrics instead.
For a list of namespaces for metrics from AWS services, see [Services That Publish Metrics.](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/aws-services-cloudwatch-metrics.html)
ok_actionsarrayThe actions to execute when this alarm transitions to the OK state from any other state. Each action is specified as an Amazon Resource Name (ARN).
alarm_actionsarrayThe list of actions to execute when this alarm transitions into an ALARM state from any other state. Specify each action as an Amazon Resource Name (ARN). For more information about creating alarms and the actions that you can specify, see [PutMetricAlarm](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_PutMetricAlarm.html) in the *API Reference*.
metric_namestringThe name of the metric associated with the alarm. This is required for an alarm based on a metric. For an alarm based on a math expression, you use Metrics instead and you can't specify MetricName.
actions_enabledbooleanIndicates whether actions should be executed during any changes to the alarm state. The default is TRUE.
metricsarrayAn array that enables you to create an alarm based on the result of a metric math expression. Each item in the array either retrieves a metric or performs a math expression.
If you specify the Metrics parameter, you cannot specify MetricName, Dimensions, Period, Namespace, Statistic, ExtendedStatistic, or Unit.
alarm_descriptionstringThe description of the alarm.
alarm_namestringThe name of the alarm. If you don't specify a name, CFN generates a unique physical ID and uses that ID for the alarm name.
If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.
statisticstringThe statistic for the metric associated with the alarm, other than percentile. For percentile statistics, use ExtendedStatistic.
For an alarm based on a metric, you must specify either Statistic or ExtendedStatistic but not both.
For an alarm based on a math expression, you can't specify Statistic. Instead, you use Metrics.
insufficient_data_actionsarrayThe actions to execute when this alarm transitions to the INSUFFICIENT_DATA state from any other state. Each action is specified as an Amazon Resource Name (ARN).
arnstring
datapoints_to_alarmintegerThe number of datapoints that must be breaching to trigger the alarm. This is used only if you are setting an "M out of N" alarm. In that case, this value is the M, and the value that you set for EvaluationPeriods is the N value. For more information, see [Evaluating an Alarm](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/AlarmThatSendsEmail.html#alarm-evaluation) in the *User Guide*.
If you omit this parameter, CW uses the same value here that you set for EvaluationPeriods, and the alarm goes to alarm state if that many consecutive periods are breaching.
thresholdnumberThe value to compare with the specified statistic.
tagsarray
regionstringAWS region.
