# AWS::ComputeOptimizer::AutomationRule Criteria
<a name="aws-properties-computeoptimizer-automationrule-criteria"></a>

 A set of conditions that specify which recommended action qualify for implementation. When a rule is active and a recommended action matches these criteria, Compute Optimizer implements the action at the scheduled run time. You can specify up to 20 conditions per filter criteria and 20 values per condition. 

## Syntax
<a name="aws-properties-computeoptimizer-automationrule-criteria-syntax"></a>

To declare this entity in your Amazon CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-computeoptimizer-automationrule-criteria-syntax.json"></a>

```
{
  "[EbsVolumeSizeInGib](#cfn-computeoptimizer-automationrule-criteria-ebsvolumesizeingib)" : {{[ IntegerCriteriaCondition, ... ]}},
  "[EbsVolumeType](#cfn-computeoptimizer-automationrule-criteria-ebsvolumetype)" : {{[ StringCriteriaCondition, ... ]}},
  "[EstimatedMonthlySavings](#cfn-computeoptimizer-automationrule-criteria-estimatedmonthlysavings)" : {{[ DoubleCriteriaCondition, ... ]}},
  "[LookBackPeriodInDays](#cfn-computeoptimizer-automationrule-criteria-lookbackperiodindays)" : {{[ IntegerCriteriaCondition, ... ]}},
  "[Region](#cfn-computeoptimizer-automationrule-criteria-region)" : {{[ StringCriteriaCondition, ... ]}},
  "[ResourceArn](#cfn-computeoptimizer-automationrule-criteria-resourcearn)" : {{[ StringCriteriaCondition, ... ]}},
