/AWS1/CL_ASCMETRICDATAQUERY

The metric data to return. Also defines whether this call is returning data for one metric only, or whether it is performing a math expression on the values of returned metric statistics to create a new time series. A time series is a series of data points, each of which is associated with a timestamp.

For more information and examples, see Advanced predictive scaling policy configurations using custom metrics in the Amazon EC2 Auto Scaling User Guide.

CONSTRUCTOR

IMPORTING

Required arguments:

iv_id TYPE /AWS1/ASCXMLSTRINGMAXLEN255 /AWS1/ASCXMLSTRINGMAXLEN255

A short name that identifies the object's results in the response. This name must be unique among all MetricDataQuery objects specified for a single scaling policy. 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 underscores. The first character must be a lowercase letter.

Optional arguments:

iv_expression TYPE /AWS1/ASCXMLSTRINGMAXLEN1023 /AWS1/ASCXMLSTRINGMAXLEN1023

The math expression to perform on the returned data, if this object is performing a math expression. This expression can use the Id of the other metrics to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions.

Conditional: Within each MetricDataQuery object, you must specify either Expression or MetricStat, but not both.

io_metricstat TYPE REF TO /AWS1/CL_ASCMETRICSTAT /AWS1/CL_ASCMETRICSTAT

Information about the metric data to return.

Conditional: Within each MetricDataQuery object, you must specify either Expression or MetricStat, but not both.

iv_label TYPE /AWS1/ASCXMLSTRINGMETRICLABEL /AWS1/ASCXMLSTRINGMETRICLABEL

A human-readable label for this metric or expression. This is especially useful if this is a math expression, so that you know what the value represents.

iv_returndata TYPE /AWS1/ASCRETURNDATA /AWS1/ASCRETURNDATA

Indicates whether to return the timestamps and raw data values of this metric.

If you use any math expressions, specify true for this value for only the final math expression that the metric specification is based on. You must specify false for ReturnData for all the other metrics and expressions used in the metric specification.

If you are only retrieving metrics and not performing any math expressions, do not specify anything for ReturnData. This sets it to its default (true).

Queryable Attributes

Id

A short name that identifies the object's results in the response. This name must be unique among all MetricDataQuery objects specified for a single scaling policy. 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 underscores. The first character must be a lowercase letter.

Accessible with the following methods

Method	Description
GET_ID()	Getter for ID, with configurable default
ASK_ID()	Getter for ID w/ exceptions if field has no value
HAS_ID()	Determine if ID has a value

Expression

The math expression to perform on the returned data, if this object is performing a math expression. This expression can use the Id of the other metrics to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions.

Conditional: Within each MetricDataQuery object, you must specify either Expression or MetricStat, but not both.

Accessible with the following methods

Method	Description
GET_EXPRESSION()	Getter for EXPRESSION, with configurable default
ASK_EXPRESSION()	Getter for EXPRESSION w/ exceptions if field has no value
HAS_EXPRESSION()	Determine if EXPRESSION has a value

MetricStat

Information about the metric data to return.

Conditional: Within each MetricDataQuery object, you must specify either Expression or MetricStat, but not both.

Accessible with the following methods

Method	Description
GET_METRICSTAT()	Getter for METRICSTAT

Label

A human-readable label for this metric or expression. This is especially useful if this is a math expression, so that you know what the value represents.

Accessible with the following methods

Method	Description
GET_LABEL()	Getter for LABEL, with configurable default
ASK_LABEL()	Getter for LABEL w/ exceptions if field has no value
HAS_LABEL()	Determine if LABEL has a value

ReturnData

Indicates whether to return the timestamps and raw data values of this metric.

If you use any math expressions, specify true for this value for only the final math expression that the metric specification is based on. You must specify false for ReturnData for all the other metrics and expressions used in the metric specification.

If you are only retrieving metrics and not performing any math expressions, do not specify anything for ReturnData. This sets it to its default (true).

Accessible with the following methods

Method	Description
GET_RETURNDATA()	Getter for RETURNDATA, with configurable default
ASK_RETURNDATA()	Getter for RETURNDATA w/ exceptions if field has no value
HAS_RETURNDATA()	Determine if RETURNDATA has a value
