FWIW: Here is the start of our workaround module:

    }
 }

resource "random_uuid" "request" {
    keepers = {
        request_guid = "${format("%v-request", var.name)}"
    }
}

data "template_file" "webtest" {
  template = <<EOF

The caveat is the required reference to the Application Insights resource via the hinden-link in tags

[jamie3]

Does anyone know if this has been implemented?

[wellingk]

After this now for my company as @jamie3 says above, anyone know if its been implemented?

[tombuildsstuff]

@jamie3 @wellingk this functionality isn't natively supported at this time - however you can use the azurerm_template_deployment resource as shown above in the interim as a workaround.

Taking a quick look into this it appears support is available in the Azure SDK for Go such that it'd be possible to implement this - but unfortunately we don't have a timeline for when we'd support this at this time (although, we'd be happy to assist with a community PR in the interim if someone's interested in seeing this natively supported 😄)

Thanks!

[AndyMoore]

i've had a go at this, and other than a few minor odds and ends i still need to sort the code looks ok (but i'm no Go expert by any stretch)

Problem I'm hitting is this:

* azurerm_application_insights_webtest.url-ping: Error creating Application Insights WebTest "testtf-weu-dev" (Resource Group "appinsights-testtf-weu-dev"): insights.WebTestsClient#CreateOrUpdate: Failure preparing request: StatusCode=0 -- Original Error: autorest: No scheme detected in URL 

On the off chance has anyone seen this before? (possibly @tombuildsstuff)

[AndyMoore]

have this working. adding tests/docs and then will raise a PR

I've left the actual test config as xml. the original request above from @cdhunt went for parameters instead - thoughts?

data "template_file" "test" {
  template = "${file("${path.module}/test.xml")}"

  vars = {
    url = "http://www.microsoft.com"
    method = "GET"
    expected_http_status_code = "200"
  }
}

resource "azurerm_application_insights_webtest" "test1" {
  #count = 0
  name                    = "test1"
  location                = "${azurerm_resource_group.appinsights.location}"
  resource_group_name     = "${azurerm_resource_group.appinsights.name}"
  application_insights_id = "${azurerm_application_insights.appinsights.id}"
  kind                    = "Ping"
  frequency               = 300
  timeout                 = 120
  enabled                 = true
  geo_locations           = ["us-tx-sn1-azr", "us-il-ch1-azr", "us-ca-sjc-azr"]
  test_configuration      = "${data.template_file.test.rendered}"
}

@AndyMoore This looks awesome, but have two questions:

1. Where would one define the contact email addresses for a failed test?
2. I've personally never used a template - do you have an example that you should share that would explain the correct formatting?

I'm super excited for this resource to be merged, so if there's any way I can help please let me know.

[AndyMoore]

i'll definitely put an example into the documentation - i've used one for testing (iirc) straight off the Microsoft site, but there's some things in there I'm not a fan of (each test will need a unique guid for example, and i'm not sure that can be bodged)

If we were to go back to the design from the original post, there'd be less flexibility, but it'd be easier to use. It'd also be reasonably trivial to extend

Or we could have both maybe.. (i think)

I've never done one of these before, so looking to someone else to give pointers

In terms of alerts @nexxai I think this i a different API - https://docs.microsoft.com/en-gb/azure/templates/microsoft.insights/2016-03-01/alertrules - so might well be a separate resource for this

[cdhunt]

@AndyMoore That makes sense given the variability it test definitions.

[AndyMoore]

fwiw @nexxai I think what you're after is https://www.terraform.io/docs/providers/azurerm/r/monitor_metric_alert.html and https://www.terraform.io/docs/providers/azurerm/r/monitor_metric_alertrule.html

will be looking to test these myself over the next few days..

This has been released in version 1.29.0 of the provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading. As an example:

provider "azurerm" {
	version = "~> 1.29.0"
}
# ... other configuration ...

[praneetloke]

@AndyMoore thanks for implementing the web test resource!

For the alerts, it looks like alertRules maps to the "Alerts" configuration of a web test. I believe what you were suggesting in your comment would actually create an alert under the "Metrics" feature of App Insights and would also show up under the "Alerts" section of Azure Monitor.

Below is a snippet from this quickstart example showing how to setup alertRules for a web test using an ARM template. From what I can tell, this closely matches with the configuration done in the portal from my screenshot below. Also, I think this is what @nexxai was referring to?

https://github.com/Azure/azure-quickstart-templates/blob/76c4e50d9520c12e333f3f597280fca960af8a6c/201-dynamic-web-tests/azuredeploy.json#L76-L111

[nexxai]

Yes, that is exactly what I was referring to, thanks @praneetloke !

Hi Guys,
I have updated my azurerm provider to 1.29.0 but still I can't find azurerm_application_insights_web_tests.
I get an error when I try to reference it.My Terraform version is 0.11.14

[ccarrido]

Error
The provider provider.azurerm does not support resource type
"azurerm_application_insights_webtest".

To recreate, copy/paste the example in the Terraform documentation: https://www.terraform.io/docs/providers/azurerm/r/application_insights_webtests.html

Also fails on my own test definition with the same error.

Versions
Terraform v0.12.0

• provider.azurerm v1.29.0

[iangore]

it would appear that the module name is actually azurerm_application_insights_web_test so either the documentation needs to be changed or the module needs to be changed.

There is also an issue with the section of the documentation "output "webtest_provisioning_state" {
value = "${azurerm_application_insights_webtest.test.provisioning_state}"
}"

This does not appear to be a valid output for the module.
