aws_cloudwatch_anomaly_detector Resource

Use the aws_cloudwatch_anomaly_detector InSpec audit resource to test properties of a single specific AWS CloudWatch anomaly detector.

The AWS::CloudWatch::AnomalyDetector type specifies an anomaly detection band for a certain metric and statistic. The band represents the expected “normal” range for the metric values. Anomaly detection bands can be used for visualization of a metric’s expected values, and for alarms.

For additional information, including details on parameters and properties, see the AWS documentation on AWS CloudWatch AnomalyDetector..

Installation

This resource is available in the Chef InSpec AWS resource pack.

See the Chef InSpec documentation on cloud platforms for information on configuring your AWS environment for InSpec and creating an InSpec profile that uses the InSpec AWS resource pack.

Syntax

Ensure that the anomaly detector exists.

describe aws_cloudwatch_anomaly_detector(metric_name: 'METRIC_NAME') do
  it { should exist }
end

Parameters

metric_name (required)

The name of the metric associated with the anomaly detection model.

Properties

namespace

The namespace of the metric associated with the anomaly detection model.

metric_name

The name of the metric associated with the anomaly detection model.

dimensions

The metric dimensions associated with the anomaly detection model.

dimensions_names

The name of the dimension.

dimensions_values

The value of the dimension.

stat

The statistic associated with the anomaly detection model.

configuration_start_time

The start time of the range to exclude.

configuration_end_time

The end time of the range to exclude.

configuration.metric_timezone

The time zone to use for the metric.

state_value

he current status of the anomaly detector’s training. The possible values are TRAINED, PENDING_TRAINING and TRAINED_INSUFFICIENT_DATA.

Examples

Ensure a namespace is available.

describe aws_cloudwatch_anomaly_detector(metric_name: 'METRIC_NAME') do
  its('namespace') { should eq 'NAMESPACE' }
end

Ensure a config name is available.

describe aws_cloudwatch_anomaly_detector(metric_name: 'METRIC_NAME') do
    its('name') { should eq 'CONFIG_NAME' }
end

Ensure a dimension name is available.

describe aws_cloudwatch_anomaly_detector(metric_name: 'METRIC_NAME') do
    its('dimensions_names') { should include 'DIMENSION_NAME' }
end

Matchers

This InSpec audit resource has the following special matchers. For a full list of available matchers, please visit our Universal Matchers page.

The controls will pass if the describe method returns at least one result.

exist

Use should to test that the entity exists.

describe aws_cloudwatch_anomaly_detector(metric_name: 'METRIC_NAME') do
  it { should exist }
end

Use should_not to test the entity does not exist.

describe aws_cloudwatch_anomaly_detector(metric_name: 'METRIC_NAME') do
  it { should_not exist }
end

be_available

Use should to check if the entity is available.

describe aws_cloudwatch_anomaly_detector(metric_name: 'METRIC_NAME') do
  it { should be_available }
end

AWS Permissions

Your Principal will need the CloudWatch:Client:DescribeAnomalyDetectorsOutput action with Effect set to Allow.
