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.

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 a metric math expression to be performed on the other metrics that you are retrieving within this
MetricDataQueries
structure.A math expression can use the
Id
of the other metrics or queries to refer to those metrics, and can also use theId

MetricDataQuery
object, you must specify eitherExpression
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

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.Stat (string) – [REQUIRED]
The statistic to use for comparison to the threshold. It can be any CloudWatch statistic or extended statistic. For more information about statistics, see CloudWatch statistics definitions.
Unit (string) –
If you omit
Unit
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 a metric math expression to be performed on the other metrics that you are retrieving within this
MetricDataQueries
structure.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 eitherExpression
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) –
Use this only if you are using a metric math expression for the SLO. Specify
true
forReturnData
for only the one expression result to use as the alarm. For all other metrics and expressions in the sameCreateServiceLevelObjective
operation, specifyReturnData
asfalse
.Period (integer) –
The granularity, in seconds, of the returned data points for this metric. 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).
AccountId (string) –
The ID of the account where this metric is located. If you are performing this operation in a monitoring account, use this to specify which source account to retrieve this metric from.
MetricThreshold (float) –
The value that the SLI metric is compared to. This parameter is required if this SLO is tracking the
Latency
metric.ComparisonOperator (string) –
The arithmetic operation to use when comparing the specified metric to the threshold. This parameter is required if this SLO is tracking the
Latency
metric.
Goal (dict) –
A structure that contains the attributes that determine the goal of the SLO. This includes the time period for evaluation and the attainment threshold.
Interval (dict) –
The time period used to evaluate the SLO. It can be either a calendar interval or rolling interval.
If you omit this parameter, a rolling interval of 7 days is used.
Note
This is a Tagged Union structure. Only one of the following top level keys can be set:
RollingInterval
,CalendarInterval
.RollingInterval (dict) –
If the interval is a rolling interval, this structure contains the interval specifications.
DurationUnit (string) – [REQUIRED]
Specifies the rolling interval unit.
Duration (integer) – [REQUIRED]
Specifies the duration of each rolling interval. For example, if
Duration
is7
andDurationUnit
isDAY
, each rolling interval is seven days.
CalendarInterval (dict) –
If the interval is a calendar interval, this structure contains the interval specifications.
StartTime (datetime) – [REQUIRED]
The date and time when you want the first interval to start. Be sure to choose a time that configures the intervals the way that you want. For example, if you want weekly intervals starting on Mondays at 6 a.m., be sure to specify a start time that is a Monday at 6 a.m.
When used in a raw HTTP Query API, it is formatted as be epoch time in seconds. For example:
1698778057
As soon as one calendar interval ends, another automatically begins.
DurationUnit (string) – [REQUIRED]
Specifies the calendar interval unit.
Duration (integer) – [REQUIRED]
Specifies the duration of each calendar interval. For example, if
Duration
is1
andDurationUnit
isMONTH
, each interval is one month, aligned with the calendar.
AttainmentGoal (float) –
The threshold that determines if the goal is being met.
If this is a period-based SLO, the attainment goal is the percentage of good periods that meet the threshold requirements to the total periods within the interval. For example, an attainment goal of 99.9% means that within your interval, you are targeting 99.9% of the periods to be in healthy state.
If this is a request-based SLO, the attainment goal is the percentage of requests that must be successful to meet the attainment goal.
If you omit this parameter, 99 is used to represent 99% as the attainment goal.
WarningThreshold (float) –
The percentage of remaining budget over total budget that you want to get warnings for. If you omit this parameter, the default of 50.0 is used.

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 a metric math expression to be performed on the other metrics that you are retrieving within this
MetricDataQueries
structure.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 eitherExpression
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) –
Use this only if you are using a metric math expression for the SLO. Specify
true
forReturnData
for only the one expression result to use as the alarm. For all other metrics and expressions in the sameCreateServiceLevelObjective
operation, specifyReturnData
asfalse
.Period (integer) –
The granularity, in seconds, of the returned data points for this metric. 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).
AccountId (string) –
The ID of the account where this metric is located. If you are performing this operation in a monitoring account, use this to specify which source account to retrieve this metric from.
BadCountMetric (list) –
If you want to count “bad requests” to determine the percentage of successful requests for this request-based SLO, specify the metric to use as “bad requests” in this structure.
(dict) –
Use this structure to define a metric or metric math expression that you want to use as for a service level objective.
Each
MetricDataQuery
in theMetricDataQueries
array specifies either a metric to retrieve, or a metric math expression to be performed on retrieved metrics. A singleMetricDataQueries
array can include as many as 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, exactly one must have true as the value forReturnData
. The result of this expression used for the SLO.For more information about metric math expressions, see CloudWatchUse metric math.
Within each
MetricDataQuery
object, you must specify eitherExpression
orMetricStat
but not both.Id (string) –
A short name used to tie this object to the results in the response. This
Id
must be unique within aMetricDataQueries
array. If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the metric math expression. The valid characters are letters, numbers, and underscore. The first character must be a lowercase letter.MetricStat (dict) –
A metric to be used directly for the SLO, or to be used in the math expression that will be used for the SLO.
Within one
MetricDataQuery
object, you must specify eitherExpression
orMetricStat
but not both.Metric (dict) –
The metric to use as the service level indicator, including the metric name, namespace, and dimensions.
Namespace (string) –
The namespace of the metric. For more information, see Namespaces.
MetricName (string) –
The name of the metric to use.
Dimensions (list) –
An array of one or more dimensions to use to define the metric that you want to use. For more information, see Dimensions.
(dict) –
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, to be used for the metric. 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.Stat (string) –
The statistic to use for comparison to the threshold. It can be any CloudWatch statistic or extended statistic. For more information about statistics, see CloudWatch statistics definitions.
Unit (string) –
If you omit
Unit
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 a metric math expression to be performed on the other metrics that you are retrieving within this
MetricDataQueries
structure.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 eitherExpression
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) –

true
forReturnData
for only the one expression result to use as the alarm. For all other metrics and expressions in the sameCreateServiceLevelObjective
operation, specifyReturnData
asfalse
.Period (integer) –
The granularity, in seconds, of the returned data points for this metric. 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).
AccountId (string) –
The ID of the account where this metric is located. If you are performing this operation in a monitoring account, use this to specify which source account to retrieve this metric from.
MetricThreshold (float) –
This value is the threshold that the observed metric values of the SLI metric are compared to.
ComparisonOperator (string) –
The arithmetic operation used when comparing the specified metric to the threshold.
EvaluationType (string) –
Displays whether this is a period-based SLO or a request-based SLO.
Goal (dict) –
This structure contains the attributes that determine the goal of an SLO. This includes the time period for evaluation and the attainment threshold.
Interval (dict) –
The time period used to evaluate the SLO. It can be either a calendar interval or rolling interval.
If you omit this parameter, a rolling interval of 7 days is used.
Note
This is a Tagged Union structure. Only one of the following top level keys will be set:
RollingInterval
,CalendarInterval
. If a client receives an unknown member it will setSDK_UNKNOWN_MEMBER
as the top level key, which maps to the name or tag of the unknown member. The structure ofSDK_UNKNOWN_MEMBER
is as follows:'SDK_UNKNOWN_MEMBER': {'name': 'UnknownMemberName'}
RollingInterval (dict) –
If the interval is a rolling interval, this structure contains the interval specifications.
DurationUnit (string) –
Specifies the rolling interval unit.
Duration (integer) –
Specifies the duration of each rolling interval. For example, if
Duration
is7
andDurationUnit
isDAY
, each rolling interval is seven days.
CalendarInterval (dict) –
If the interval is a calendar interval, this structure contains the interval specifications.
StartTime (datetime) –
The date and time when you want the first interval to start. Be sure to choose a time that configures the intervals the way that you want. For example, if you want weekly intervals starting on Mondays at 6 a.m., be sure to specify a start time that is a Monday at 6 a.m.
When used in a raw HTTP Query API, it is formatted as be epoch time in seconds. For example:
1698778057
As soon as one calendar interval ends, another automatically begins.
DurationUnit (string) –
Specifies the calendar interval unit.
Duration (integer) –
Specifies the duration of each calendar interval. For example, if
Duration
is1
andDurationUnit
isMONTH
, each interval is one month, aligned with the calendar.
AttainmentGoal (float) –
The threshold that determines if the goal is being met.
If this is a period-based SLO, the attainment goal is the percentage of good periods that meet the threshold requirements to the total periods within the interval. For example, an attainment goal of 99.9% means that within your interval, you are targeting 99.9% of the periods to be in healthy state.
If this is a request-based SLO, the attainment goal is the percentage of requests that must be successful to meet the attainment goal.
If you omit this parameter, 99 is used to represent 99% as the attainment goal.
WarningThreshold (float) –
The percentage of remaining budget over total budget that you want to get warnings for. If you omit this parameter, the default of 50.0 is used.
