# PutMetricAlarm Creates or updates an alarm and associates it with the specified metric, metric math expression, anomaly detection model, Metrics Insights query, or PromQL query. For more information about using a Metrics Insights query for an alarm, see [Create alarms on Metrics Insights queries](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Create_Metrics_Insights_Alarm.html). Alarms based on anomaly detection models cannot have Auto Scaling actions. When this operation creates an alarm, the alarm state is immediately set to `INSUFFICIENT_DATA`. For PromQL alarms, the alarm state is instead immediately set to `OK`. 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. If you are an IAM user, you must have Amazon EC2 permissions for some alarm operations: + The `iam:CreateServiceLinkedRole` permission for all alarms with EC2 actions + The `iam:CreateServiceLinkedRole` permissions to create an alarm with Systems Manager OpsItem or response plan actions. The first time you create an alarm in the AWS Management Console, the AWS CLI, or by using the PutMetricAlarm API, CloudWatch creates the necessary service-linked role for you. The service-linked roles are called `AWSServiceRoleForCloudWatchEvents` and `AWSServiceRoleForCloudWatchAlarms_ActionSSM`. For more information, see [AWS service-linked role](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_terms-and-concepts.html#iam-term-service-linked-role). Each `PutMetricAlarm` action has a maximum uncompressed payload of 120 KB. **Cross-account alarms** You can set an alarm on metrics in the current account, or in another account. To create a cross-account alarm that watches a metric in a different account, you must have completed the following pre-requisites: + The account where the metrics are located (the *sharing account*) must already have a sharing role named **CloudWatch-CrossAccountSharingRole**. If it does not already have this role, you must create it using the instructions in **Set up a sharing account** in [ Cross-account cross-Region CloudWatch console](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Cross-Account-Cross-Region.html#enable-cross-account-cross-Region). The policy for that role must grant access to the ID of the account where you are creating the alarm. + The account where you are creating the alarm (the *monitoring account*) must already have a service-linked role named **AWSServiceRoleForCloudWatchCrossAccount** to allow CloudWatch to assume the sharing role in the sharing account. If it does not, you must create it following the directions in **Set up a monitoring account** in [ Cross-account cross-Region CloudWatch console](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Cross-Account-Cross-Region.html#enable-cross-account-cross-Region). ## Request Parameters ** ActionsEnabled ** Indicates whether actions should be executed during any changes to the alarm state.

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](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/AlarmThatSendsEmail.html#percentiles-with-low-samples). Valid Values: `evaluate | ignore` Type: String Length Constraints: Minimum length of 1. Maximum length of 255. Required: No ** EvaluationCriteria ** The evaluation criteria for the alarm. For each `PutMetricAlarm` operation, you must specify either `MetricName`, a `Metrics` array, or an `EvaluationCriteria`. If you use the `EvaluationCriteria` parameter, you cannot include the `Namespace`, `MetricName`, `Dimensions`, `Period`, `Unit`, `Statistic`, `ExtendedStatistic`, `Metrics`, `Threshold`, `ComparisonOperator`, `ThresholdMetricId`, `EvaluationPeriods`, or `DatapointsToAlarm` parameters of `PutMetricAlarm` in the same operation. Instead, all evaluation parameters are defined within this structure. For an example of how to use this parameter, see the **PromQL alarm** example on this page. Type: [EvaluationCriteria](API_EvaluationCriteria.md) object **Note: **This object is a Union. Only one member of this object can be specified or returned. Required: No ** EvaluationInterval ** The frequency, in seconds, at which the alarm is evaluated. Valid values are 10, 20, 30, and any multiple of 60. This parameter is required for alarms that use `EvaluationCriteria`, and cannot be specified for alarms configured with `MetricName` or `Metrics`. Type: Integer Valid Range: Minimum value of 10.

Length Constraints: Minimum length of 1. Maximum length of 1024. Required: No ** MetricName ** The name for the metric associated with the alarm. For each `PutMetricAlarm` operation, you must specify either `MetricName`, a `Metrics` array, or an `EvaluationCriteria`. 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. Type: String Length Constraints: Minimum length of 1. Maximum length of 255. Required: No ** Metrics ** 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`, a `Metrics` array, or an `EvaluationCriteria`. 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](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_MetricDataQuery.html). 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. Type: Array of [MetricDataQuery](API_MetricDataQuery.md) objects Required: No ** Namespace ** The namespace for the metric associated specified in `MetricName`. Type: String Length Constraints: Minimum length of 1. Maximum length of 255. Pattern: `[^:].*` Required: No ** OKActions ** The actions to execute when this alarm transitions to an `OK` state from any other state. Each action is specified as an Amazon Resource Name (ARN).

Length Constraints: Minimum length of 1. Maximum length of 1024. Required: No ** Period ** The length, in seconds, used each time the metric specified in `MetricName` is evaluated. Valid values are 10, 20, 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, 20, or 30 only for metrics that are stored by a `PutMetricData` call with a `StorageResolution` of 1. If you specify a period of 10, 20, 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\$1DATA status. Specifying 10, 20, 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](https://aws.amazon.com/cloudwatch/pricing/). An alarm's total current evaluation period can be no longer than seven days, so `Period` multiplied by `EvaluationPeriods` can't be more than 604,800 seconds. For alarms with a period of less than one hour (3,600 seconds), the total evaluation period can't be longer than one day (86,400 seconds). Type: Integer Valid Range: Minimum value of 10. Required: No ** Statistic ** The statistic for the metric specified in `MetricName`, other than percentile. For percentile statistics, use `ExtendedStatistic`. When you call `PutMetricAlarm` and specify a `MetricName`, you must specify either `Statistic` or `ExtendedStatistic,` but not both. Type: String Valid Values: `SampleCount | Average | Sum | Minimum | Maximum` Required: No ** Tags ** 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](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_TagResource.html) or [UntagResource](https://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_UntagResource.html). To use this field to set tags for an alarm when you create it, you must be signed on with both the `cloudwatch:PutMetricAlarm` and `cloudwatch:TagResource` permissions. Type: Array of [Tag](API_Tag.md) objects Required: No ** Threshold ** The value against which the specified statistic is compared. This parameter is required for alarms based on static thresholds, but should not be used for alarms based on anomaly detection models. Type: Double Required: No ** ThresholdMetricId ** 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. Type: String Length Constraints: Minimum length of 1. Maximum length of 255. Required: No ** TreatMissingData ** 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](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/AlarmThatSendsEmail.html#alarms-and-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. This parameter is not applicable to PromQL alarms. Type: String Length Constraints: Minimum length of 1. Maximum length of 255. Required: No ** Unit ** 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. Type: String Valid 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 | None` Required: No ## Errors For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md). ** LimitExceeded ** The quota for alarms for this customer has already been reached. ** message ** HTTP Status Code: 400 ## Examples ### Static Threshold Alarm The following example creates an alarm that notifies an SNS group when the CPUUtilization of a certain instance goes over 40% for three out of four periods. #### Sample Request ``` { "Namespace": "AWS/EC2", "MetricName": "CPUUtilization", "Dimensions": [ { "Name": "InstanceId", "Value": "i-1234567890abcdef0" } ], "AlarmActions": [ "arn:aws:sns:us-west-1:123456789012:my_sns_topic" ], "ComparisonOperator": "GreaterThanThreshold", "DatapointsToAlarm": 3, "EvaluationPeriods": 4, "Period": 60, "Statistic": "Average", "Threshold": 40, "AlarmDescription": "CPU Utilization of i-1234567890abcdef0 with 40% as threshold", "AlarmName": "Instance i-1234567890abcdef0 CPU Utilization" } ``` ### Metric Math Function Alarm The following example retrieves three metrics that each track a different type of connection error to a custom service. These error counts are first summed in one expression, then divided by total connection attempts in another expression. The alarm goes to the ALARM state if the error rate is over 40% for three consecutive periods, and notifies two different SNS groups. #### Sample Request ``` { "AlarmActions": [ "arn:aws:sns:us-west-1:123456789012:my_sns_topic", "arn:aws:sns:us-west-1:123456789012:my_other_sns_topic" ], "ComparisonOperator": "GreaterThanThreshold", "EvaluationPeriods": 3, "Threshold": 40, "AlarmDescription": "MyService Aggregate Connection Error Rate (Alarm at 40%)", "AlarmName": "MyService Connection Error Rate", "Metrics": [ { "MetricStat": { "Metric": { "MetricName": "ConnectionsFailed", "Namespace": "MyService" }, "Period": 60, "Stat": "Sum" }, "Id": "m1", "ReturnData": "False" }, { "MetricStat": { "Metric": { "MetricName": "ConnectionsDropped", "Namespace": "MyService" }, "Period": 60, "Stat": "Sum" }, "Id": "m2", "ReturnData": "False" }, { "MetricStat": { "Metric": { "MetricName": "RequestsThrottled", "Namespace": "MyService" }, "Period": 60, "Stat": "Sum" }, "Id": "m3", "ReturnData": "False" }, { "MetricStat": { "Metric": { "MetricName": "ConnectionAttempts", "Namespace": "MyService" }, "Period": 60, "Stat": "Sum" }, "Id": "m4", "ReturnData": "False" }, { "Id": "error_total", "Expression": "m1+m2+m3", "ReturnData": "False" }, { "Id": "error_rate", "Expression": "(error_total/m4)*100", "ReturnData": "true", "Label": "Total Connection Error Rate" } ] } ``` ### Anomaly Detection Model Alarm The following example sets an alarm on an anomaly detection model. The Id of `m1` is assigned to the `CPUUtilization` metric of an instance. `t1` is the anomaly detection model function for that metric, and uses 3 standard deviations to set the width of the band. The setting of `ThresholdMetricId` is `t1` and the `ComparisonOperator` is `LessThanLowerOrGreaterThanUpperThreshold`, specifying that the alarm goes to alarm state when the metric value is outside the anomaly model band in either direction for two consecutive evaluation periods. #### Sample Request ``` { "AlarmActions": [ "arn:aws:sns:us-west-1:123456789012:my_sns_topic", "arn:aws:sns:us-west-1:123456789012:my_other_sns_topic" ], "AlarmName": "MyAlarmName", "AlarmDescription": "This alarm uses an anomaly detection model", "Metrics": [ { "Id": "m1", "ReturnData": true, "MetricStat": { "Metric": { "MetricName": "CPUUtilization", "Namespace": "AWS/EC2", "Dimensions": [ { "Name": "instanceId", "Value": "i-1234567890abcdef0" } ] }, "Stat": "Average", "Period": 60 } }, { "Id": "t1", "Expression": "ANOMALY_DETECTION_BAND(m1, 3)" } ], "EvaluationPeriods": 2, "ThresholdMetricId": "t1", "ComparisonOperator": "LessThanLowerOrGreaterThanUpperThreshold" } ``` ### Metrics Insights query alarm The following example sets an alarm on an Metrics Insights query. #### Sample Request ``` { "AlarmActions": [ "arn:aws:sns:us-west-1:123456789012:my_sns_topic", "arn:aws:sns:us-west-1:123456789012:my_other_sns_topic" ], "AlarmName": "MetricsInsightsAlarm", "AlarmDescription": "This alarm uses a Metrics Insights query", "Metrics": [ { "Id": "m1", "Expression": "SELECT AVG(CPUUtilization) FROM SCHEMA("AWS/EC2", InstanceId)", "Period": 60, "Label": "Average CPUUtilization query" } ], "EvaluationPeriods": 1, "Threshold": 65, "ComparisonOperator": "GreaterThanThreshold" } ``` ### PromQL alarm The following example creates an alarm based on a PromQL query. The alarm evaluates the PromQL query every 30 seconds and its contributors (matching series) transition to the ALARM state if they are continuously breaching for 300 seconds (pending period). Contributors transition back to OK after they are no longer breaching for 120 seconds (recovery period). #### Sample Request ``` { "AlarmName": "HighCPUPromQLAlarm", "AlarmDescription": "Alarm when average CPU exceeds 80% using PromQL", "AlarmActions": [ "arn:aws:sns:us-west-1:123456789012:my_sns_topic" ], "EvaluationCriteria": { "PromQLCriteria": { "Query": "avg(cpu_utilization_percent) > 80", "PendingPeriod": 300, "RecoveryPeriod": 120 } }, "EvaluationInterval": 30 } ``` ## See Also For more information about using this API in one of the language-specific AWS SDKs, see the following: + [AWS Command Line Interface V2](https://docs.aws.amazon.com/goto/cli2/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for .NET V4](https://docs.aws.amazon.com/goto/DotNetSDKV4/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for C\$1\$1](https://docs.aws.amazon.com/goto/SdkForCpp/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for Go v2](https://docs.aws.amazon.com/goto/SdkForGoV2/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for Java V2](https://docs.aws.amazon.com/goto/SdkForJavaV2/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for JavaScript V3](https://docs.aws.amazon.com/goto/SdkForJavaScriptV3/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for Kotlin](https://docs.aws.amazon.com/goto/SdkForKotlin/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for PHP V3](https://docs.aws.amazon.com/goto/SdkForPHPV3/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for Python](https://docs.aws.amazon.com/goto/boto3/monitoring-2010-08-01/PutMetricAlarm) + [AWS SDK for Ruby V3](https://docs.aws.amazon.com/goto/SdkForRubyV3/monitoring-2010-08-01/PutMetricAlarm)
