'Azure ARM template creating duplicate resources

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.

                    "id": "FailureAnomaliesDetector"

                "scope": [ "[resourceId('microsoft.insights/components', 'AiApp')]" ],

                }
            }
        }        
    ]
    }

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

Solution 1:^[1]

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')]"
}
}
