Ensure that an Activity Log Alert exists for Service Health

Description

Create an activity log alert for Service Health.

Rationale

Monitoring for Service Health events provides insight into service issues, planned maintenance, security advisories, and other changes that may affect the Azure services and regions in use.

Impact

There is no charge for creating activity log alert rules.

Audit Procedure

Using Azure Portal

1. Go to Monitor.
2. Click Alerts.
3. Click Alert rules.
4. Ensure an alert rule exists for a subscription with Condition set to Service names=All, Event types=All and Target resource type set to Subscription.
5. If an alert rule is found for step 4, click the name of the alert rule.
6. Ensure the Actions panel displays an action group configured to notify appropriate personnel.
7. Repeat steps 1-6 for each subscription.

Using Azure CLI

Run the following command to list activity log alerts:

az monitor activity-log alert list --subscription <subscription-id>

For each activity log alert, run the following command:

az monitor activity-log alert show --subscription <subscription-id> --resource-group <resource-group> --activity-log-alert-name <activity-log-alert>

Ensure an alert exists for ServiceHealth with scopes set to a subscription ID.

Repeat for each subscription.

Using PowerShell

Run the following command to locate ServiceHealth alert rules for a subscription:

Get-AzActivityLogAlert -SubscriptionId <subscription-id> | where-object {$_.ConditionAllOf.Equal -match "ServiceHealth"} | select-object Location,Name,Enabled,ResourceGroupName,ConditionAllOf

Ensure that at least one ServiceHealth alert rule is returned.

Repeat for each subscription.

Expected Result

An activity log alert rule should exist for Service Health with ServiceHealth category and an action group assigned to notify appropriate personnel.
