@Generated(value="com.amazonaws:awsjavasdkcodegenerator") public class MetricDataQuery extends Object implements Serializable, Cloneable
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 math expression on metric data. A single
GetMetricData
call can include up to 100 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.
