az monitor activity-log alert create --subscription <subscription-id> --resource-group <resource-group> --name <alert-rule> --condition category=ServiceHealth and properties.incidentType=Incident --scope /subscriptions/<subscription-id> --action-group <action-group>

Remediate from PowerShell

Create the Conditions object:

$conditions = @()
$conditions += New-AzActivityLogAlertAlertRuleAnyOfOrLeafConditionObject -Field category -Equal ServiceHealth
$conditions += New-AzActivityLogAlertAlertRuleAnyOfOrLeafConditionObject -Field properties.incidentType -Equal Incident

Retrieve the Action Group information and store in a variable:

$actionGroup = Get-AzActionGroup -ResourceGroupName <resource-group> -Name <action-group>

Create the Actions object:

$actionObject = New-AzActivityLogAlertActionGroupObject -Id $actionGroup.Id

Create the Scope object:

$scope = "/subscriptions/<subscription-id>"

Create the activity log alert rule:

New-AzActivityLogAlert -Name <alert-rule> -ResourceGroupName <resource-group> -Condition $conditions -Scope $scope -Location global -Action $actionObject -Subscription <subscription-id> -Enabled $true

Repeat for each subscription requiring remediation.
