Azure ARM template creating duplicate resources

Question

Deploying incrementally an ARM template with a simple Application Insight resource, is automatically creating FailureAnomaliesDetector alert rule. Which is a problem in case such rule already exists.

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "resources": [
        {
            "type": "Microsoft.Insights/components",
            "apiVersion": "2020-02-02",
            "location": "[resourceGroup().location]",
            "name": "AiApp",
            "kind": "web",
            "properties": {
                "Application_Type": "web",
                "IngestionMode": "ApplicationInsights",
                "SamplingPercentage": 12.5,
                "publicNetworkAccessForIngestion": "Enabled",
                "publicNetworkAccessForQuery": "Enabled"
            }
        },
        {
            "type": "microsoft.insights/actionGroups",
            "apiVersion": "2019-06-01",
            "name": "ActionGroup",
            "location": "Global",
            "properties": {
                "groupShortName": "AiApp",
                "enabled": true,
                "emailReceivers": "[createObject('emailAddress','john@example.com','name','email','useCommonAlertSchema',true())]"
            },
            "dependsOn": [ "[resourceId('microsoft.insights/components', 'AiApp')]" ]
        },
        {
            "type": "microsoft.alertsmanagement/smartdetectoralertrules",
            "apiVersion": "2021-04-01",
            "name": "AlertAnomalies",
            "location": "global",
            "dependsOn": [ "[resourceId('microsoft.insights/actionGroups', 'ActionGroup')]" ],
            "properties": {
                "description": "Failure Anomalies notifies you of an unusual rise in the rate of failed HTTP requests or dependency calls.",
                "state": "Enabled",
                "severity": "Sev2",
                "frequency": "PT1M",
                "detector": {
                    "id": "FailureAnomaliesDetector"
                },
                "scope": [ "[resourceId('microsoft.insights/components', 'AiApp')]" ],
                "actionGroups": {
                    "groupIds": [ "[resourceId('microsoft.insights/actionGroups', 'ActionGroup')]" ]
                }
            }
        }        
    ]
    }

I was not able to find any hint in the documentation to stop it creating for my case unwanted rule. Any Idea?

We have tried with the below ARM template to create simple Application insight resource and can able to deploy successfully without creating FailureAnomaliesDetector .

TEMPLATE:-

{
"$schema": "http://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json#",
"contentVersion": "1.0.0.0",
"parameters": {
"name": {
"type": "string"
},
"type": {
"type": "string"
},
"regionId": {
"type": "string"
},
"tagsArray": {
"type": "object"
},
"requestSource": {
"type": "string"
},
"workspaceResourceId": {
"type": "string"
}
},
"resources": [
{
"name": "[parameters('name')]",
"type": "microsoft.insights/components",
"location": "[parameters('regionId')]",
"tags": "[parameters('tagsArray')]",
"apiVersion": "2020-02-02-preview",
"dependsOn": [],
"properties": {
"ApplicationId": "[parameters('name')]",
"Application_Type": "[parameters('type')]",
"Flow_Type": "Redfield",
"Request_Source": "[parameters('requestSource')]",
"WorkspaceResourceId": "[parameters('workspaceResourceId')]"
}
}

Well that is the case, it works fine without it, but if you define it, than you have a problem. I must deploy it because the alert group with email addresses is attached to the rule. — Jan, Mar 29 '22 at 20:51
Hello @Jan, As per my understanding , If we want to create an alert with email address then we can add into our script as well. If we don't want then we can use the above template. — AjayKumarGhose, Mar 30 '22 at 03:38
