Syntax

public class ComparisonOperator : ConstantClass

The ComparisonOperator type exposes the following members

Constructors

	Name	Description
	ComparisonOperator(string)	This constant constructor does not need to be called if the constant you are attempting to use is already defined as a static instance of this class. This constructor should be used to construct constants that are not defined as statics, for instance if attempting to use a feature that is newer than the current version of the SDK.

Properties

	Name	Type	Description
	Value	System.String	Inherited from Amazon.Runtime.ConstantClass.

Methods

Note:

Asynchronous operations (methods ending with Async) in the table below are for .NET 4.5 or higher. For .NET 3.5 the SDK follows the standard naming convention of BeginMethodName and EndMethodName to indicate asynchronous operations - these method pairs are not shown in the table below.

	Name	Description
	FindValue(string)	Finds the constant for the unique value.

Fields

Name	Type	Description
GreaterThanOrEqualToThreshold	Amazon.CloudWatch.ComparisonOperator	Constant GreaterThanOrEqualToThreshold for ComparisonOperator
GreaterThanThreshold	Amazon.CloudWatch.ComparisonOperator	Constant GreaterThanThreshold for ComparisonOperator
GreaterThanUpperThreshold	Amazon.CloudWatch.ComparisonOperator	Constant GreaterThanUpperThreshold for ComparisonOperator
LessThanLowerOrGreaterThanUpperThreshold	Amazon.CloudWatch.ComparisonOperator	Constant LessThanLowerOrGreaterThanUpperThreshold for ComparisonOperator
LessThanLowerThreshold	Amazon.CloudWatch.ComparisonOperator	Constant LessThanLowerThreshold for ComparisonOperator

Examples

This example shows how to create an alarm for a metric.

Create metric alarm example

var client = new AmazonCloudWatchClient();

var dimension = new Dimension
{
  Name = "Desktop Machine Metrics",
  Value = "Virtual Desktop Machine Usage"
};

var request = new PutMetricAlarmRequest
{
  ActionsEnabled = true,
  AlarmActions = new List<string>() 
    { "arn:aws:sns:us-east-1:80398EXAMPLE:CodingTestResults" },
  AlarmDescription = "Too many instances offline",
  AlarmName = "Offline Instances",
  ComparisonOperator = ComparisonOperator.GreaterThanOrEqualToThreshold,
  Dimensions = new List<Dimension>() { dimension },
  EvaluationPeriods = 1,
  MetricName = "Desktop Machines Offline",
  Namespace = "Example.com Custom Metrics",
  Period = (int)TimeSpan.FromMinutes(5).TotalSeconds,
  Statistic = new Statistic("Maximum"),
  Threshold = 5,
  Unit = StandardUnit.Count
};

client.PutMetricAlarm(request);
