[ aws . cloudwatch ]
Creates or updates an alarm and associates it with the specified metric, metric math expression, anomaly detection model, or Metrics Insights query. For more information about using a Metrics Insights query for an alarm, see Create alarms on Metrics Insights queries .
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
. 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:
iam:CreateServiceLinkedRole
permission for all alarms with EC2 actionsiam:CreateServiceLinkedRole
permissions to create an alarm with Systems Manager OpsItem or response plan actions.The first time you create an alarm in the Amazon Web Services Management Console, the 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 Amazon Web Services 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:

--metric-name
(string)
The name for the metric associated with the alarm. For each
PutMetricAlarm
operation, you must specify eitherMetricName
or aMetrics
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
, orExtendedStatistic
parameters. Instead, you specify all this information in theMetrics
array.
--namespace
(string)
The namespace for the metric associated specified inMetricName
.
--statistic
(string)
The statistic for the metric specified in
MetricName
, other than percentile. For percentile statistics, useExtendedStatistic
. When you callPutMetricAlarm
and specify aMetricName
, you must specify eitherStatistic
orExtendedStatistic,
but not both.Possible values:
SampleCount
Average
Sum
Minimum
Maximum
--extended-statistic
(string)
The extended statistic for the metric specified in
MetricName
. When you callPutMetricAlarm
and specify aMetricName
, you must specify eitherStatistic
orExtendedStatistic
but not both.If you specify
ExtendedStatistic
, the following are valid values:
p90
tm90
tc90
ts90
wm90
IQM
PR(*n* :*m* )
where n and m are values of the metricTC(*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 .
--dimensions
(list)
The dimensions for the metric specified in
MetricName
.(structure)
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish
InstanceId
as a dimension name, and the actual instance ID as the value for that dimension.You can assign up to 30 dimensions to a metric.
Name -> (string)
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (:
). ASCII control characters are not supported as part of dimension names.Value -> (string)
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character. ASCII control characters are not supported as part of dimension values.
Shorthand Syntax:
Name=string,Value=string ...
JSON Syntax:
[
{
"Name": "string",

}
...
]
--period
(integer)
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 theMetrics
array.Be sure to specify 10 or 30 only for metrics that are stored by a
PutMetricData
call with aStorageResolution
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 byEvaluationPeriods
cannot be more than 86,400 seconds.
--unit
(string)
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 theINSUFFICIENT DATA
state.Possible values:
Seconds
Microseconds
Milliseconds
Bytes
Kilobytes
Megabytes
Gigabytes
Terabytes
Bits
Kilobits
Megabits
Gigabits

--evaluation-periods
(integer)
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.
--datapoints-to-alarm
(integer)
The number of data points 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. For more information, see Evaluating an Alarm in the Amazon CloudWatch User Guide .
--threshold
(double)
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.
--comparison-operator
(string)
The arithmetic operation to use when comparing the specified statistic and threshold. The specified statistic value is used as the first operand.
The values
LessThanLowerOrGreaterThanUpperThreshold
,LessThanLowerThreshold
, andGreaterThanUpperThreshold
are used only for alarms based on anomaly detection models.Possible values:
GreaterThanOrEqualToThreshold
GreaterThanThreshold
LessThanThreshold
LessThanOrEqualToThreshold
LessThanLowerOrGreaterThanUpperThreshold
LessThanLowerThreshold
GreaterThanUpperThreshold
--treat-missing-data
(string)
Sets how this alarm is to handle missing data points. If
TreatMissingData
is omitted, the default behavior ofmissing
is used. For more information, see Configuring How CloudWatch Alarms Treats Missing Data .Valid Values:
breaching | notBreaching | ignore | missing
Note
Alarms that evaluate metrics in theAWS/DynamoDB
namespace alwaysignore
missing data even if you choose a different option forTreatMissingData
. When anAWS/DynamoDB
metric has missing data, alarms that evaluate that metric remain in their current state.
--evaluate-low-sample-count-percentile
(string)
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 specifyevaluate
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
--metrics
(list)
An array of
MetricDataQuery
structures that enable you to create an alarm based on the result of a metric math expression. For eachPutMetricAlarm
operation, you must specify eitherMetricName
or aMetrics
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 settingReturnData
to true for this object in the array. For more information, see MetricDataQuery .If you use the
Metrics
parameter, you cannot include theNamespace
,MetricName
,Dimensions
,Period
,Unit
,Statistic
, orExtendedStatistic
parameters ofPutMetricAlarm
in the same operation. Instead, you retrieve the metrics you are using in your math expression as part of theMetrics
array.(structure)
This structure is used in both
GetMetricData
andPutMetricAlarm
. The supported use of this structure is different for those two operations.When used in
GetMetricData
, it indicates the metric data to return, and whether this call is just retrieving a batch set of data for one metric, or is performing a Metrics Insights query or a math expression. A singleGetMetricData
call can include up to 500MetricDataQuery
structures.When used in
PutMetricAlarm
, it enables you to create an alarm based on a metric math expression. EachMetricDataQuery
in the array specifies either a metric to retrieve, or a math expression to be performed on retrieved metrics. A singlePutMetricAlarm
call can include up to 20MetricDataQuery
structures in the array. The 20 structures can include as many as 10 structures that contain aMetricStat
parameter to retrieve a metric, and as many as 10 structures that contain theExpression
parameter to perform a math expression. Of thoseExpression
structures, one must havetrue
as the value forReturnData
. The result of this expression is the value the alarm watches.Any expression used in a
PutMetricAlarm
operation must return a single time series. For more information, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .Some of the parameters of this structure also have different uses whether you are using this structure in a
GetMetricData
operation or aPutMetricAlarm
operation. These differences are explained in the following parameter list.Id -> (string)
A short name used to tie this object to the results in the response. This name must be unique within a single call toGetMetricData
. If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.MetricStat -> (structure)
The metric to be returned, along with statistics, period, and units. Use this parameter only if this object is retrieving a metric and not performing a math expression on returned data.
Within one MetricDataQuery object, you must specify either
Expression
orMetricStat
but not both.Metric -> (structure)
The metric to return, including the metric name, namespace, and dimensions.
Namespace -> (string)
The namespace of the metric.MetricName -> (string)
The name of the metric. This is a required field.Dimensions -> (list)
The dimensions for the metric.
(structure)
A dimension is a name/value pair that is part of the identity of a metric. Because dimensions are part of the unique identifier for a metric, whenever you add a unique name/value pair to one of your metrics, you are creating a new variation of that metric. For example, many Amazon EC2 metrics publish
InstanceId
as a dimension name, and the actual instance ID as the value for that dimension.You can assign up to 30 dimensions to a metric.
Name -> (string)
The name of the dimension. Dimension names must contain only ASCII characters, must include at least one non-whitespace character, and cannot start with a colon (:
). ASCII control characters are not supported as part of dimension names.Value -> (string)
The value of the dimension. Dimension values must contain only ASCII characters and must include at least one non-whitespace character. ASCII control characters are not supported as part of dimension values.Period -> (integer)
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by a
PutMetricData
call that includes aStorageResolution
of 1 second.If the
StartTime
parameter specifies a time stamp that is greater than 3 hours ago, you must specify the period as follows or no data points in that time range is returned:
- Start time between 3 hours and 15 days ago - Use a multiple of 60 seconds (1 minute).
- Start time between 15 and 63 days ago - Use a multiple of 300 seconds (5 minutes).
- Start time greater than 63 days ago - Use a multiple of 3600 seconds (1 hour).
Stat -> (string)
The statistic to return. It can include any CloudWatch statistic or extended statistic.Unit -> (string)
When you are using a
Put
operation, this defines what unit you want to use when storing the metric.In a
Get
operation, if you omitUnit
then all data that was collected with any unit is returned, along with the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the operation returns only data that was collected with that unit specified. If you specify a unit that does not match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.Expression -> (string)
This field can contain either a Metrics Insights query, or a metric math expression to be performed on the returned data. For more information about Metrics Insights queries, see Metrics Insights query components and syntax in the Amazon CloudWatch User Guide .
A math expression can use the
Id
of the other metrics or queries to refer to those metrics, and can also use theId
of other expressions to use the result of those expressions. For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide .Within each MetricDataQuery object, you must specify either
Expression
orMetricStat
but not both.Label -> (string)
A human-readable label for this metric or expression. This is especially useful if this is an expression, so that you know what the value represents. If the metric or expression is shown in a CloudWatch dashboard widget, the label is shown. If Label is omitted, CloudWatch generates a default.
You can put dynamic expressions into a label, so that it is more descriptive. For more information, see Using Dynamic Labels .
ReturnData -> (boolean)
When used in
GetMetricData
, this option indicates whether to return the timestamps and raw data values of this metric. If you are performing this call just to do math expressions and do not also need the raw data returned, you can specifyfalse
. If you omit this, the default oftrue
is used.When used in
PutMetricAlarm
, specifytrue
for the one expression result to use as the alarm. For all other metrics and expressions in the samePutMetricAlarm
operation, specifyReturnData
as False.Period -> (integer)
The granularity, in seconds, of the returned data points. For metrics with regular resolution, a period can be as short as one minute (60 seconds) and must be a multiple of 60. For high-resolution metrics that are collected at intervals of less than one minute, the period can be 1, 5, 10, 30, 60, or any multiple of 60. High-resolution metrics are those metrics stored by aPutMetricData
operation that includes aStorageResolution of 1 second
.AccountId -> (string)
The ID of the account where the metrics are located.
If you are performing a
GetMetricData
operation in a monitoring account, use this to specify which account to retrieve this metric from.If you are performing a
PutMetricAlarm
operation, use this to specify which account contains the metric that the alarm is watching.
