#evaluate_low_sample_count_percentileString

Used only for alarms based on percentiles. If you specify ignore, the alarm state does not change during periods with too few data points to be statistically significant. If you specify evaluate or omit this parameter, the alarm is always evaluated and possibly changes state no matter how many data points are available. For more information, see Percentile-Based CloudWatch Alarms and Low Data Samples.

Valid Values: evaluate | ignore

#evaluation_periodsInteger

The 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.

An alarm's total current evaluation period can be no longer than one day, so this number multiplied by Period cannot be more than 86,400 seconds.

#extended_statisticString

The extended statistic for the metric specified in MetricName. When you call PutMetricAlarm and specify a MetricName, you must specify either Statistic or ExtendedStatistic but not both.

  • tc90

  • ts90

  • wm90

  • IQM

  • PR(n:m) where n and m are values of the metric

  • TC(X%:X%) where X is between 10 and 90 inclusive.

  • TM(X%:X%) where X is between 10 and 90 inclusive.

  • TS(X%:X%) where X is between 10 and 90 inclusive.

  • WM(X%:X%) where X is between 10 and 90 inclusive.

For more information about these extended statistics, see CloudWatch statistics definitions.

Returns:

#metric_nameString

The name for the metric associated with the alarm. For each PutMetricAlarm operation, you must specify either MetricName or a Metrics array.

If you are creating an alarm based on a math expression, you cannot specify this parameter, or any of the Namespace, Dimensions, Period, Unit, Statistic, or ExtendedStatistic parameters. Instead, you specify all this information in the Metrics array.

#metricsArray<Types::MetricDataQuery>

An array of MetricDataQuery structures that enable you to create an alarm based on the result of a metric math expression. For each PutMetricAlarm operation, you must specify either MetricName or a Metrics array.

Each item in the Metrics array either retrieves a metric or performs a math expression.

One item in the Metrics array is the expression that the alarm watches. You designate this expression by setting ReturnData to true for this object in the array. For more information, see MetricDataQuery.

If you use the Metrics parameter, you cannot include the Namespace, MetricName, Dimensions, Period, Unit, Statistic, or ExtendedStatistic parameters of PutMetricAlarm in the same operation. Instead, you retrieve the metrics you are using in your math expression as part of the Metrics array.

#periodInteger

The length, in seconds, used each time the metric specified in MetricName is evaluated. Valid values are 10, 30, and any multiple of 60.

Period is required for alarms based on static thresholds. If you are creating an alarm based on a metric math expression, you specify the period for each metric within the objects in the Metrics array.

Be sure to specify 10 or 30 only for metrics that are stored by a PutMetricData call with a StorageResolution of 1. If you specify a period of 10 or 30 for a metric that does not have sub-minute resolution, the alarm still attempts to gather data at the period rate that you specify. In this case, it does not receive data for the attempts that do not correspond to a one-minute data resolution, and the alarm might often lapse into INSUFFICENT_DATA status. Specifying 10 or 30 also sets this alarm as a high-resolution alarm, which has a higher charge than other alarms. For more information about pricing, see Amazon CloudWatch Pricing.

An alarm's total current evaluation period can be no longer than one day, so Period multiplied by EvaluationPeriods cannot be more than 86,400 seconds.

Returns:

  • (Integer)

#tagsArray<Types::Tag>

A list of key-value pairs to associate with the alarm. You can associate as many as 50 tags with an alarm. To be able to associate tags with the alarm when you create the alarm, you must have the cloudwatch:TagResource permission.

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.

If you are using this operation to update an existing alarm, any tags you specify in this parameter are ignored. To change the tags of an existing alarm, use TagResource or UntagResource.

If this is an alarm based on an anomaly detection model, make this value match the ID of the ANOMALY_DETECTION_BAND function.

For an example of how to use this parameter, see the Anomaly Detection Model Alarm example on this page.

If your alarm uses this parameter, it cannot have Auto Scaling actions.

#treat_missing_dataString

Sets how this alarm is to handle missing data points. If TreatMissingData is omitted, the default behavior of missing is used. For more information, see Configuring How CloudWatch Alarms Treats Missing Data.

Valid Values: breaching | notBreaching | ignore | missing

Alarms that evaluate metrics in the AWS/DynamoDB namespace always ignore missing data even if you choose a different option for TreatMissingData. When an AWS/DynamoDB metric has missing data, alarms that evaluate that metric remain in their current state.

#unitString

The unit of measure for the statistic. For example, the units for the Amazon EC2 NetworkIn metric are Bytes because NetworkIn tracks the number of bytes that an instance receives on all network interfaces. You can also specify a unit when you create a custom metric. Units help provide conceptual meaning to your data. Metric data points that specify a unit of measure, such as Percent, are aggregated separately. If you are creating an alarm based on a metric math expression, you can specify the unit for each metric (if needed) within the objects in the Metrics array.

If you don't specify Unit, CloudWatch retrieves all unit types that have been published for the metric and attempts to evaluate the alarm. Usually, metrics are published with only one unit, so the alarm works as intended.

However, if the metric is published with multiple types of units and you don't specify a unit, the alarm's behavior is not defined and it behaves unpredictably.

We recommend omitting Unit so that you don't inadvertently specify an incorrect unit that is not published for this metric. Doing so causes the alarm to be stuck in the INSUFFICIENT DATA state.

Returns:

  • (String)
