Azure Application Insights Alert Rule in ARM Template - azure

I'm trying to setup Application Insights to be attached against Function App, and few Web API's (Azure App Service).
Ideally we want the whole deployment process to be fully automated from VSTS Build and Release so we don't have to setup the resource from Azure Portal.
I've created the ARM template for it and managed to get it to create a new Azure resource of Application Insight, however it's not showing the other settings that I want (i.e. Alert Rules, Billing Type, and Daily Data Cap).
Is setting up Alert Rules currently available via ARM template? if so can someone please help and verify if the ARM template I've got :)?

I've finally found out that the issue was due to me having same Alert Rule names (wasn't aware that alert rules are treated as resource and need to have unique names..).
So I ended up renaming the alert to something different, redeployed the solution and it finally creates the alert rules :).

ARM template storage account not found while creating Azure Function App

I have an ARM template which creates a Storage Account, App Service Plan, Application Insights and a Function App. In the dependsOn section of the Function App, I configured it to be depending on the other three resources. But when I deploy the template, it fails with the following error:
Status Message: The Resource 'Microsoft.Storage/storageAccounts/dummystorage' under resource group 'dummy-rg' was not found.
I see that the Storage Account, ASP and App Insights are being created first, followed by the Function App. So it seems the dependency is being honored. It's almost like the Storage Account provisioning is not completely finished when the Function App is being created. As you can see in the template below, the Function App resource uses the listKeys to get the Storage Account keys as part of the provisioning.
Does anybody have any idea how I can prevent this from happening? I've read everything in the docs regarding dependencies, and I believe this should just work.
One remark is that the storage account is being deployed based on a condition. I can't imagine it has something to do with my issue, but I just wanted to mention it.

I think you're running into this: https://bmoore-msft.blog/2020/07/26/resource-not-found-dependson-is-not-working/
TLDR;
listKeys is called in a separate job in the deployment engine and gets called early if that resource (i.e. your storage) is not in the same deployment.
you don't need to nest your storageAccount deployment, doesn't hurt but doesn't help. If your storageAccount deployment is unconditional, then it will help because ARM will wait before running listKeys.
if you need the condition, the only fix is to nest the function app deployment and set a dependency on the conditional storageAccount (the dependency need not be conditional ARM will handle that). You need to set the evaluation scope to "inner" on that nested deployment.
That help?
I noticed your dependsOn for Storage looks like this:
"dependsOn": [
"[parameters('appInsightsName')]",
"[parameters('appServicePlanName')]",
"[resourceId('Microsoft.Resources/deployments', variables('storageAccountDeploymentName'))]"
Whereas my despendsOn for Storage Account and Blob Container looks like this... could that be the reason it's not working? I have never used Microsoft.Resources/deployments (FYI my ARM Template deployment is working)
"dependsOn": [
"[resourceId('Microsoft.Storage/storageAccounts/blobServices/containers', variables('StorageAccountName'), 'default', variables('BlobContainerName2'))]",
"[resourceId('Microsoft.Storage/storageAccounts', variables('StorageAccountName'))]"
Alternatively:
You could drop the conditional and deploy the Storage Account each time. If it exists no change, if it doesn't exist then it's created.
The only caveat to this is if you change something on the storage account post-deployment or if the Storage account has a dynamically set name based on Timestamp or GUID etc.
I realize this is a work around, but it should solve your problem barring the caveat above.

Nested ARM template and dependsOn in another Resource Group

I am trying to create a Function App with VNET Integration in ARM. I have made all that work just fine in one main template.
Now I have a new requirement where the VNET needs to be in another RG and thus seperate from the Func App RG, but the Func App still needs to have VNET integration to the VNET in the other RG.
I'm struggling how to define the ARM template, so that I deploy the Func App in one RG and VNET in another. The hard part is how to define this so that the Func App integrates into a VNET in another RG in the same ARM template using nested template.
Here is my ARM template:
"resources": [{
"type": "Microsoft.Resources/deployments",
"apiVersion": "2019-10-01",
"name": "nestedTemplate",
"resourceGroup": "[parameters('VNETPeered_RG_Name')]",

},
"subnets": [{

"properties": {

}
}

}

}
}
},

}
}]
]
}
On this I get the following error when I try to deploy it with az deployment group command from az cli:
Deployment failed. Correlation ID: 39b0173b-8a51-42c5-a796-1d3427556194. {

}
}
reference() will work but TLDR; it's a little heavyweight
https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/template-functions-resource#resourceid
is all you need in this case. To "reference" any resource in ARM you'll use the resourceId - there are a handful of functions to help but it really helps if you understand the basics of the resourceId, which is summarized here:
https://learn.microsoft.com/en-us/azure/azure-resource-manager/templates/template-functions-resource#return-value-6
When you want a resourceId to a resource in the same deployment (which is not the same as the same template) you can use the shorthand version
resourceId({namespace/resourceType}, {resourceName})
If it's in a different RG, you need to add the RG param, and if it's in a different sub you need to add that too. I can't tell for certain with your snippet, but it looks like all you need in your case is this (assuming the vnet and fn app are in the same subscription):
"subnetResourceId": "[resourceId(parameters('VNETPeered_RG_Name'), 'Microsoft.Network/virtualNetworks/subnets', variables('virtual_network_name'), variables('subnet_name'))]"
That help?
Your problem is in this part of code:
"properties": {
"subnetResourceId": "[reference(resourceId('RG-FunctionsGroup','Microsoft.Network/virtualNetworks/subnets', 'vn-MY-VNET', 'sn-MY-SUBNET'),'2020-05-01')]",
"isSwift": true
}
You are pointing the subnet with the wrong resource group. Change the resource group where the vnet and the subnet is deployed.
"properties": {
"subnetResourceId": "[reference(resourceId(parameters('VNETPeered_RG_Name'),'Microsoft.Network/virtualNetworks/subnets', variables('virtual_network_name'), variables('subnet_name')),'2020-05-01')]",
"isSwift": true
}

Azure - Set WebSocket On from ARM json template

I'm trying to turn WebSockets On for an Azure WebApp from an Azure ARM json template that deploys my whole infrastructure.
Here is an extract with regards to the Azure Web App. It doesn't work, i.e the WebSockets are still Off. I unsuccessfully tried different spelling: webSocketsEnabled or WebSockets.
"resources":[
{
"name": "[variables('MyApp')]",
"type": "Microsoft.Web/sites",
"location": "Brazil South",
"apiVersion": "2016-08-01",
"dependsOn": [
"[resourceId('Microsoft.Web/serverfarms', variables('MyAppPlanBrazil'))]"
],
"tags": {
"[concat('hidden-related:', resourceId('Microsoft.Web/serverfarms', variables('MyAppPlanBrazil')))]": "Resource",
"displayName": "MyAppAppBrazil"
},
"properties": {
"name": "[variables('MyAppPlanBrazil')]",
"serverFarmId": "[resourceId('Microsoft.Web/serverfarms', variables('MyAppPlanBrazil'))]",
"siteConfig": {
"AlwaysOn": true,
"webSocketsEnabled": true,
"connectionStrings": [
{
...
},
{
...
},
]
}
}
]
UPDATE
As suggested in answer below I updated the apiVersion to "2016-08-01" but this still doesn't work.
Also note that while my schema is the one described here, apiVersion is squiggled in VS and it says the authorized value is "2015-08-01" only.
UPDATE2
I tried the solutions below. They work for their authors but not for me. I guess the problem is elsewhere. My infrastructure is already deployed and I try to update it with webSocketsEnabled. Whereas in the solution below I imagine the authors directly create the web app with webSocketsEnabled.
Also, I coupled webSocketsEnabled with alwaysOn whereas the pricing tier of my webapp doesn't allow "AlwaysOn" (as it says in the portal I need to upgrade to use that feature) so I'll try without alwaysOn.
UPDATE3
At the end, the above template worked when I removed AlwaysOn.
Thank you to those who tried to help me.
Set your api version to this: "2016-08-01"
Use
"webSocketsEnabled": true
This is from the Microsoft.Web/sites template reference:
https://learn.microsoft.com/en-us/azure/templates/microsoft.web/sites
The api version you are using (2015-08-01) from:
https://github.com/Azure/azure-resource-manager-schemas/blob/master/schemas/2015-08-01/Microsoft.Web.json
Doesn't have web sockets in it, but the later one:
https://github.com/Azure/azure-resource-manager-schemas/blob/master/schemas/2016-08-01/Microsoft.Web.json
Does have webSocketsEnabled.
Please have a try to use the following code. It works correctly on my side.
Updated: add whole test arm template and you could have a try to use the following code with your service plan name and resource group name

},
"properties": {
"key1": "value1",
"key2": "value2"
}
}
]
}],
"outputs": {}
}
Test Result:
All the above solution should work.
My initial snippet worked as well ... as soon as I removed alwaysOn.
Indeed, I was using a free tiers App Service Plan for which alwaysOn is not available. While there was no errors or anything else indicating something wrong, I could not set webSocketEnabled and alwaysOn at the same time in that case.

Assign Web App to an existing service plan in ARM template

I'm trying to attach existing service plan to a new Web App in Azure Resource Manager template. The Service Plan is already up and running and not part of that arm template
You've probably figured this out by now, but incase someone else clicks into this thread as I did I'll post this.
You can use the resourceId function to reference the exisiting Service Plan.
Then simply use this in the properties for serverFarmId in the template.
"properties": {
"serverFarmId": "[resourceId('Microsoft.Web/serverfarms', parameters('hostingPlanName'))]"
}
So basicalliy exactly what Fei Han example shows, but you need to remove the dependsOn (and of course the Service Plan resource).
My service plan was in a different resource group so I also have to provide RG name
"serverFarmId": "[resourceId('plangroup',
'Microsoft.Web/serverfarms', parameters('hostingPlanName'))]"

You said the service plan is not created, is it not an existing service plan? If you’d like to deploy both app service plan and web app to Azure via Azure PowerShell with Resource Manager template, please refer to the following ARM template.

Azure Resource Manager alarm creation

I'm trying to use an Azure Resource Manager template to create an alert in Application Insights. The problem I'm having is what value I should put for resourceUri. I've tried a few different values, I'm not sure if it's supposed to be the resource I'm monitoring or something else. The documentation is most unhelpful. When I try with the value below it gives me a validation error.
It's also not clear how I actually associate the alert with the component. Is it supposed to be nested as a resource within the component? I have a dependsOn referencing the component but from what I understand that would just ensure the other resource gets created first.
{
"$schema": "https://schema.management.azure.com/schemas/2015-01-01/deploymentTemplate.json",
"contentVersion": "1.0.0.0",
"resources": [
{
"apiVersion": "2014-04-01",

},
{
"apiVersion": "2014-04-01",
"type": "Microsoft.Insights/alertrules",
"name": "testAlert1",
"dependsOn": [
"[concat('Microsoft.Insights/components/', 'testmetrics')]"
],
"location": "Central US",
"properties": {

"resourceUri": "/Microsoft.Web/sites/mytestsite"
},
"operator": "GreaterThan",

}
}
}
]
}
The resourceUrl should refer to the Application Insights service in following format:
"resourceUri": "[concat(resourceGroup().id, '/providers/Microsoft.Insights/components/', 'testmetrics')]"
A great way to figure out how to write these templates correctly (if you can't find a reference in the Github repository for ARM quickstart templates) is to create a resource group in the Azure portal, configure your system and then export to a JSON template (found in the "Setting" blade when you click your resource group).
I just created an example Application Insights resource with an alert and got the one below.
You can see how the dependency is nested and the correct syntax. Also note that location for Central US is provided as "centralus"
