Bicep Module for an Anomaly Alert

Fri, 05 May 2023 17:00:37 +0200

In our CAF Landing Zone Starter Kit, the implementation of the Anomaly Alert on the subscription was missing until now. This is almost complete. Here is a possible implementation of the Anomaly Alert as a Bicep module.

Anomaly Alert Bicep

targetScope = 'subscription'

@description('Name of the Anomaly Alert')
param aaName string = 'myAnomalyAlert'

@description('Display Name of the Anomaly Alert')
param aaDisplayName string = 'Anomaly Alert'

@description('Subject of the Anomaly Alert email notification')
param aaNotificationSubject string = 'Anomaly Alert detected for your Subscription'

@description('Email address to send the Anomaly Alert notification to')
param aaNotificationTo string

@description('Message of the Anomaly Alert email notification')
param aaNotificationMessage string = 'The Anomaly Alert has been triggered for your Subscription ${subscription().subscriptionId}. Please check the Cost Management Dashboard for more details.'

@description('Start date of the Anomaly Alert (default: now)')
param aaStartDate string = utcNow('u')

@description('End date of the Anomaly Alert (default: 1 year from now)')
param aaEndDate string = dateTimeAdd(utcNow('u'), 'P1Y')

// The kind of the Anomaly Alert must be 'InsightAlert'
var aaKind = 'InsightAlert'

resource myAnomalyAlert 'Microsoft.CostManagement/scheduledActions@2022-10-01' = {
 name: aaName
 kind: aaKind
 properties: {
 displayName: aaDisplayName
 scope: '/subscriptions/${subscription().subscriptionId}'
 notification: {
 subject: aaNotificationSubject
 to: [
 aaNotificationTo
 ]
 message: aaNotificationMessage
 }
 status: 'Enabled'
 viewId: resourceId('Microsoft.CostManagement/views/','ms:DailyAnomalyByResourceGroup')
 schedule: {
 endDate: aaEndDate
 frequency: 'Daily'
 startDate: aaStartDate
 }
 }
}

Deploying the Module

The module can be applied using the Azure CLI. The important thing is to verify that you are in the correct subscription first. Then the deployment is straightforward:
