Assembly: AWSSDK.CloudWatch.dll
Version: 3.x.y.z


public class ComparisonOperator : ConstantClass

The ComparisonOperator type exposes the following members


Public Method 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.


Public Property Value System.String Inherited from Amazon.Runtime.ConstantClass.



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.

Public Method Static Method FindValue(string)

Finds the constant for the unique value.

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