# aws\_cloudwatch\_alarm
|
|
|
|
Use the `aws_cloudwatch_alarm` InSpec audit resource to test properties of a single Cloudwatch Alarm.
|
|
|
|
Cloudwatch Alarms are currently identified using the metric name and metric namespace. Future work may allow other approaches to identifying alarms.

|
## Availability
|
|
|
|
### Installation
|
|
|
|
This resource is distributed along with InSpec itself. You can use it automatically.
|
|
|
|
### Version
|
|
|
|
This resource first became available in v2.0.16 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
An `aws_cloudwatch_alarm` resource block searches for a Cloudwatch Alarm, specified by several search options. If more than one Alarm matches, an error occurs.
|
|
|
|
# Look for a specific alarm
|
|
aws_cloudwatch_alarm(
|
|
metric_name: 'my-metric-name',
|
|
metric_namespace: 'my-metric-namespace',
|
|
) do
|
|
it { should exist }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Examples
|
|
|
|
The following examples show how to use this InSpec audit resource.
|
|
|
|
### Ensure an Alarm has at least one alarm action
|
|
|
|
describe aws_cloudwatch_alarm(
|
|
metric: 'my-metric-name',
|
|
metric_namespace: 'my-metric-namespace',
|
|
) do
|
|
its('alarm_actions') { should_not be_empty }
|
|
end
|
|
|
|
<br>

## Properties
|
|
|
|
* `alarm_actions`
|
|
|
|
## Property Examples
|
|
|
|
### alarm\_actions
|
|
|
|
`alarm_actions` returns a list of strings. Each string is the ARN of an action that will be taken should the alarm be triggered.
|
|
|
|
# Ensure that the alarm has at least one action
|
|
describe aws_cloudwatch_alarm(
|
|
metric: 'bed-metric',
|
|
metric_namespace: 'my-metric-namespace',
|
|
) do
|
|
its('alarm_actions') { should_not be_empty }
|

|
|
metric: 'good-metric',
|
|
metric_namespace: 'my-metric-namespace',
|
|
) do
|
|
it { should exist }
|
|
end
|
|
|
|
# Disallow alarms based on bad-metric
|
|
describe aws_cloudwatch_alarm(
|
|
metric: 'bed-metric',
|
|
metric_namespace: 'my-metric-namespace',
|
|
) do
|
|
