Terraform deployment for 'Work pace based Application Insight' on Azure - azure

Question

I have been trying to figure out a way to prepare a terraform template for my app service/az function where I can connect it to application Insight while creating them through Terraform. Well the it worked, BUT the application Insight shows
Migrate this resource to Workspace-based Application Insights to gain support for all of the capabilities of Log Analytics, including Customer-Managed Keys and Commitment Tiers. Click here to learn more and migrate in a few clicks.
How do I acheive it from terraform? As from the documentation page of terraform there is no mention of such setup. Appreciate you help on this.
Here is the terraform code for az-function
resource "azurerm_linux_function_app" "t_funcapp" {
name = "t-function-app"
location = local.resource_location
resource_group_name = local.resource_group_name
service_plan_id = azurerm_service_plan.t_app_service_plan.id
storage_account_name = azurerm_storage_account.t_funcstorage.name
storage_account_access_key = azurerm_storage_account.t_funcstorage.primary_access_key
site_config {
application_stack {
java_version = "11"
}
remote_debugging_enabled = false
ftps_state = "AllAllowed"
}
app_settings = {
APPINSIGHTS_INSTRUMENTATIONKEY = "${azurerm_application_insights.t_appinsights.instrumentation_key}"
}
depends_on = [
azurerm_resource_group.t_rg,
azurerm_service_plan.t_app_service_plan,
azurerm_storage_account.t_funcstorage,
azurerm_application_insights.t_appinsights
]
}
Here is the terraform code for app insight
resource "azurerm_application_insights" "t_appinsights" {
name = "t-appinsights"
location = local.resource_location
resource_group_name = local.resource_group_name
application_type = "web"
depends_on = [
azurerm_log_analytics_workspace.t_workspace
]
}
output "instrumentation_key" {
value = azurerm_application_insights.t_appinsights.instrumentation_key
}
output "app_id" {
value = azurerm_application_insights.t_appinsights.app_id
}

Answer 1

You must create a Log Analytics Workspace and add it to your Application Insights.
For example
resource "azurerm_log_analytics_workspace" "example" {
name = "workspace-test"
location = local.resource_location
resource_group_name = local.resource_group_name
sku = "PerGB2018"
retention_in_days = 30
}
resource "azurerm_application_insights" "t_appinsights" {
name = "t-appinsights"
location = local.resource_location
resource_group_name = local.resource_group_name
workspace_id = azurerm_log_analytics_workspace.example.id
application_type = "web"
}
output "instrumentation_key" {
value = azurerm_application_insights.t_appinsights.instrumentation_key
}
output "app_id" {
value = azurerm_application_insights.t_appinsights.app_id
}
Hope this helps!
