[−][src]Struct rusoto_emr::CloudWatchAlarmDefinition
The definition of a CloudWatch metric alarm, which determines when an automatic scaling activity is triggered. When the defined alarm conditions are satisfied, scaling activity begins.
Fields
comparison_operator: String
Determines how the metric specified by MetricName
is compared to the value specified by Threshold
.
dimensions: Option<Vec<MetricDimension>>
A CloudWatch metric dimension.
evaluation_periods: Option<i64>
The number of periods, expressed in seconds using Period
, during which the alarm condition must exist before the alarm triggers automatic scaling activity. The default value is 1
.
metric_name: String
The name of the CloudWatch metric that is watched to determine an alarm condition.
namespace: Option<String>
The namespace for the CloudWatch metric. The default is AWS/ElasticMapReduce
.
period: i64
The period, in seconds, over which the statistic is applied. EMR CloudWatch metrics are emitted every five minutes (300 seconds), so if an EMR CloudWatch metric is specified, specify 300
.
statistic: Option<String>
The statistic to apply to the metric associated with the alarm. The default is AVERAGE
.
threshold: f64
The value against which the specified statistic is compared.
unit: Option<String>
The unit of measure associated with the CloudWatch metric being watched. The value specified for Unit
must correspond to the units specified in the CloudWatch metric.
