Class MetricDataQuery
- All Implemented Interfaces:
Serializable
,SdkPojo
,ToCopyableBuilder<MetricDataQuery.Builder,
MetricDataQuery>
This structure is used in both GetMetricData
and PutMetricAlarm
. 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
single GetMetricData
call can include up to 500 MetricDataQuery
structures.
When used in PutMetricAlarm
, it enables you to create an alarm based on a metric math expression. Each
MetricDataQuery
in the array specifies either a metric to retrieve, or a math expression to be performed
on retrieved metrics. A single PutMetricAlarm
call can include up to 20 MetricDataQuery
structures in the array. The 20 structures can include as many as 10 structures that contain a
MetricStat
parameter to retrieve a metric, and as many as 10 structures that contain the
Expression
parameter to perform a math expression. Of those Expression
structures, one must
have true
as the value for ReturnData
. 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 a PutMetricAlarm
operation. These differences are explained in
the following parameter list.

Method Details
-
id
A short name used to tie this object to the results in the response. This name must be unique within a single call to
GetMetricData
. 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.- Returns:

-
metricStat
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.- Returns:
- 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.
-
expression
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.- Returns:
- 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
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
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.- Returns:

, specifytrue

operation, specifyReturnData
as False.
-
period
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
operation that includes aStorageResolution of 1 second
.- Returns:
- 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

operation that includes aStorageResolution of 1 second
.
-
accountId
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.- Returns:
- 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.

equalsBySdkFields
Description copied from interface:SdkPojo
Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields

- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
toString
Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value. -
