Documentation
data CustomizedMetricSpecification Source #
Represents a CloudWatch metric of your choosing for a target tracking scaling policy to use with Amazon EC2 Auto Scaling.
To create your customized metric specification:
- Add values for each required property from CloudWatch. You can use an existing metric, or a new metric that you create. To use your own metric, you must first publish the metric to CloudWatch. For more information, see Publish custom metrics in the Amazon CloudWatch User Guide.
- Choose a metric that changes proportionally with capacity. The value of the metric should increase or decrease in inverse proportion to the number of capacity units. That is, the value of the metric should decrease when capacity increases.
For more information about the CloudWatch terminology below, see Amazon CloudWatch concepts.
Each individual service provides information about the metrics, namespace, and dimensions they use. For more information, see Amazon Web Services services that publish CloudWatch metrics in the Amazon CloudWatch User Guide.

Instances
newCustomizedMetricSpecification :: CustomizedMetricSpecification Source #
Create a value of CustomizedMetricSpecification
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:dimensions:CustomizedMetricSpecification'
, customizedMetricSpecification_dimensions
- The dimensions of the metric.
Conditional: If you published your metric with dimensions, you must specify the same dimensions in your scaling policy.
$sel:metricName:CustomizedMetricSpecification'
, customizedMetricSpecification_metricName
- The name of the metric. To get the exact metric name, namespace, and
dimensions, inspect the
Metric
object that is returned by a call to
ListMetrics.
$sel:metrics:CustomizedMetricSpecification'
, customizedMetricSpecification_metrics
- The metrics to include in the target tracking scaling policy, as a
metric data query. This can include both raw metric and metric math
expressions.
$sel:namespace:CustomizedMetricSpecification'
, customizedMetricSpecification_namespace
- The namespace of the metric.
$sel:statistic:CustomizedMetricSpecification'
, customizedMetricSpecification_statistic
- The statistic of the metric.
$sel:unit:CustomizedMetricSpecification'
, customizedMetricSpecification_unit
- The unit of the metric. For a complete list of the units that CloudWatch
supports, see the
MetricDatum
data type in the Amazon CloudWatch API Reference.
customizedMetricSpecification_dimensions :: Lens' CustomizedMetricSpecification (Maybe [MetricDimension]) Source #
The dimensions of the metric.
Conditional: If you published your metric with dimensions, you must specify the same dimensions in your scaling policy.
customizedMetricSpecification_metricName :: Lens' CustomizedMetricSpecification (Maybe Text) Source #
The name of the metric. To get the exact metric name, namespace, and dimensions, inspect the Metric object that is returned by a call to ListMetrics.
customizedMetricSpecification_metrics :: Lens' CustomizedMetricSpecification (Maybe [TargetTrackingMetricDataQuery]) Source #
The metrics to include in the target tracking scaling policy, as a metric data query. This can include both raw metric and metric math expressions.
customizedMetricSpecification_namespace :: Lens' CustomizedMetricSpecification (Maybe Text) Source #
The namespace of the metric.
customizedMetricSpecification_statistic :: Lens' CustomizedMetricSpecification (Maybe MetricStatistic) Source #
The statistic of the metric.
customizedMetricSpecification_unit :: Lens' CustomizedMetricSpecification (Maybe Text) Source #
The unit of the metric. For a complete list of the units that CloudWatch supports, see the MetricDatum data type in the Amazon CloudWatch API Reference.
